I learned to use a dozer on a Euclid C6 with a rope lifted blade. Very noisy GM 6 cyl when you take your foot off and call up full power but a wonderful machine. I.was 19 then
A D 9 G is a good old tractor. It will run for ever. The RPMs are low, and the horse power is reasonable. The D9H is another story. They upped the RPMs and increased the horse power. The H engine will run for 7,000 hr (more or less) then it will need to be overhauled, and most likely need to have the block cut for a spacer under the liner. That is a 1 or 2 time deal, then you will need to cut the block into the water jacket and install a Z insert. After that, you throw the block away and start new. The D9G will just keep on chugging. They also have a magnetic oil strainer on the inlet side of the transmission oil cooler plus another one before the transmission pump. The H has only the one in front of the pump. If you loose a power train component, you will also have to change the cooler, every time.
Tommy Rottn Great observational skills, what makes you say we are in Boston? I take it you mean Boston USA? If you notice the traffic is on the wrong side of the road for the USA!! What is sad about the video if you don't mind me asking??
Tommy Rottn Thanks for your reply, the trailer was fine, admittedly it's not ideal coming off the side, but we didn't want to take it off the back into oncoming traffic and cause an accident. Also we didn't want to chew the road up or break any kerb stones and then have to pay to get them replaced. We were also on a tight time schedule so after weighing up our options this was the way we decided to go. Cheers 👍
I started working for caterpillar dealers when I got out of the army in ‘78. The old D8’s and D9’s all had the pony motors. Some even had a rope to start it. Had a compression release to get the engine turning and were all direct drive with a clutch lever. The good old days.
id like to have a beer or a coffee with the guy with the stick, i guarantee you a guy with a stick and tape measure suspenders would have some interesting stuff to say, i just know it.
Wish the video didn't end at the best part, it's really cool to see these big old dozers crawl around especially down trails like that. Awesome CAT though 👍
My Dad worked at Cat in Peoria on the assembly line. I remember him talking about the D-9. I was just a kid So I don’t remember much. He was there from 1952 to 1982 I believe.
@David Anderson ,Thankyou for commenting very interesting ,your farther would have been their when they were rolling out the very first D9 model ,the 18/19a in 1955. Cheers .
45 years runnin big iron........mostly Ohio, WVa. Pa. Area We called them pony motors but east coast coulda been different. I was taught with a hand crank pony motor. Starter shaft stuck vertical out the top of the hood crank its self was detachable and kept in a locked tool box to prevent un authorized use. Pony had a magneto lesson number one PULL the crank if you pushed it and it kicked back it would break your thumb.Once running pony heated the engine coolant an would spin the engine over to pre oil the diesel. Best cold weather starting required no either for the diesel you could crank the diesel indefinitely before tripping the compression release to run position........All this now useless information and 2 bucks will get ya a coffee ( That was a dime when pony motors were new )
+pinslayer 45 AARP, it’s always great to hear these old stories about the old Cats,love playing and restoring them.Yes had a couple close calls with an old D8 8r pony motor starting handle.cheers.
A friend of mine has a Cat dozer that was real old in the 90s when I lived near him, I don't remember the model but not nearly as large as this D9G, but I well remember having to use a pull rope to start the damnable 2 cyl? pony engine, oh man that thing was a pain to get started- lots of pulls and winding the rope back on it.
While I was in SCARWAF building runways in Korea during the war, we got in some new boots who were supposed to be dozer operators. They sent one to get a D8 about a mile away and later looked up to see it barely moving headed their way. He was creeping so slowly that the motor pool sergeant went to see what was the matter. When he got there, he found the guy hadn't started the engine and was using the donkey to move it. He explained that he was sick the day they taught how to start the engine and he'd never learned how. Said they were always running when he got to run them.
Not me. I remember pony motor starts. Had a huge Cat generator that was a pony motor start, huge smoke rings getting it going in the morning at the Hot Plant. That was a push Cat must had some major dirt work going on. They were there to push the scrapers.
Roy Grillo I take it you must be based in the USA? In the U.K. where we are based they are called donkey engines, but yes your right in other parts of the world they are called pony motors/engines. Cheers
Thanks for the feed back, operatored just about all cats from cable to D11. One of the greatest joys of my life. Yep, good ole U. S. of A. Thanks for the great video.
Roy Grillo no problems at all glad you enjoyed it 👍 we are just in the final stages of fitting a cable operated blade to a D8-8R so will hopefully have some footage of that soon doing some dozing hopefully. You still operating machines, what are you on now? Cheers
About 4 years ago I had to retire do to health issues from Vietnam. It is amazing how proficient one can be as time goes by. The most fun I had was chasing Cat627 double barrel scrapers with a D9 making the deep cuts in man made lakes in giant home subdivisions. When time was precious we would buddy blade in triples and move mountains of earth. I learn to operate when I worked on a farm at 10 years old. Those were the days. Cheers to you
Roy Grillo Thanks for the comment, sorry to hear about the health issues, I hope it's not too serious. Did you ever come across the Caterpillar 830m rubber tired tractor with box and blade while in Vietnam?
Johnny Allen yes the decompressor was connected, we edited some of the video and took a lot of the turning over an decompression out as it's not very exciting to watch. Also the donkey engine was running low on fuel so needed to get the main engine started as quick as possible as we didn't want to be running around to the garage getting petrol when your paying for the low loader by the hour!! Cheers 👍
Here is illegal to drive on paved roads with steal wheels. I have same issue with my traktor, up side, no flats or tyre changes ever even after +60 years on it. Strange/funny thing, old machines don't seems rust d so fails, superior metal choices back then.
Needs to spend fifty bucks and but an exhaust pipe. Dont know why they dropped the trailer when I was in the service we would load and unload the old D-8s with a Blade off the side of the old Load King 60T lowboys a couple time a day over seas but we did it backwards.
+Ozarks Farmer Hansen ,it’s actually strapped to the front grill ,as she literally just come off the boat from Caterpillar “Home Land”,and you need to reduce height as much as possible on those trips !.👍
There's a lot of replaceable wood on the trailer deck, and it's designed to be used that way... Driving on to dirt also provides better traction, and he avoided tearing up the asphalt by going off the side and directly down that gravel road.
+Bostonpowercat ,What is a donkey Start & how did it get it's name. Thanks. I thoughtI heard a 2Stroke engine blarring away helping the D9G turn over. Very interesting this video.
Had to take it off cross carriage due to it being unloaded on a busy public highway, didn't want to break all the curb stones and have trouble with the local authorities!! We couldn't pull the trailer off the road as it was to narrow and boggy, admittedly coming straight off the back would have been easier, but it wasn't possible. Cheers
Allan Lerfald generally hauling d9 loader or rock truck, i used apsp, pierced steel plank,air force surplus for outrigger base,thats the airfied plank, once in rough spot i walked 992 off trailer and threw a psp 30 feet in air.

Are you the owner of that dozer? I built engines for CAT in the 1980's now I walk with a walking stick like the gentleman in the video.heavy machinery is in my DNA.
I drove a D7G when I was 14. My folks were building their house and the guy was digging out for the pool, and I was riding around on my little dune buggy; he says, "I'll let you drive this if I can drive that"! I did three or four scoops with him on helping then he let me do a couple by myself!!
Afraid of nothing but a track rolling off to the inside on a steep grade but the tracks looked decent on that ole boy so he should be able to walk pretty proudly I would think
Never heard the term "donkey start" before. Now I understand. What happens when the starter motor won't start? lol Looks like a lumbering giant from yesteryear for sure. Cheers from Louisiana.
Man do I remember those days, as a kid sitting on the heavy equipment with my Dad starting the caterpillar road graders and bulldozers , thanks for the memories.
After reading through many, many post. Piecing it all together you guys got it pretty much right. But first big mistake was he didn't use the compression release at all. That's the lever on the dash support by his right foot. You can see the control rod going to the head. 1st You turn the lever with your hand to release the compression before you do anything else. Next I didn't see him look at the oil pressure gauge at all. Sometimes it takes 30sec to a min to get the pressure up. After engaging the pony motor clutch and the oil pressure comes up then you kick the compression release with your foot to engage it followed by adding fuel if it's not to cold. As far as the trailer goes I looked at the video over and over and can't see where any damage was done to the wood at all or the trailer. If you look you can see they put plywood down before they loaded the Cat. Even after the plywood got tore up during the 90 degree turn it looks like it survived well enough to keep the grousers clear of deck. Detaching the goose neck put the front of the trailer on the ground making it more stable reducing any twist on the frame. If you look at the video you can see it looks like he may have dumped the air on the rear axles as there was very little twist or movement as the Cat point loaded the side of the trailer. I think I would have blocked under the frame to the ground in a few places and a few more for the ramp but it looks like it fared very well. Now then for all you pretty boys that wax their trailers you need to look up some videos of cross country pipeline moves on the back roads of Pennsylvania. Most of the moves are side loaded for speed and efficiency. I've even seen two side booms loaded side by side with one boom down toward the front and one toward the back. Yes it wasn't legal but that's the way it was done. They make square turns on back roads at a T intersection that I could take all your money that it couldn't be done. Road drivers. Ha!
Back in 86, Grants Pass, old 38 stuck out in the woods. First job after diesel school. Pony would`t stay running. Spent two days in rain. No luck. Worked on pony carb whole day. Boss yelling. Wasting time. Finally got pony good. After many, many tries, finally got main running. Boss very, very quiet. Never yelled again.
still laughing hours later. Reminds me of the Dinosaurs tv comedy show that lasted a year or so back in the 90s where when the mother in law gets old you toss her off a cliff
Operated some highly modified D9’s in Greenland in 67. Stretched frames, 55 inch wide track pads, some had 600 gallon nose tank, 300 gallon belly tank, and a 150 in the rear. Others had 14 foot wide blades.. dragged some very, very heavy and long loads over the ice cap. YT search Camp Century to get a view of some of them at work.
Ok I've ran an old 1957 D7 with a Pony Motor never heard them called Donkey Start why not use tires and drive it off the front and keep from tearing up the trailer
what a treat to find this channel.I loved those monster yellow giants. My pop and an uncle bought an army surplus cat dozer in "46.Their idea was to dig cellers in WNY state, tiny town south of BFLO.Mty older bro, a cousin and I had the job to paint it yellow,sort of yellow.I was 10 they were 14, what a summer we had.They had figured how to start the monster altho we were were told ,on pain of decapitation,to never start if unless an older cousin was with us,Who follows directions????WE had turned my grandfathers acreage into our 40 acre playground, after watching pop and uncle digging a few cellars we figured nuthing to it so we dug a pond one day.WE were grounded for a few days but by time my bro and cousin were 16 they were digging cellars and ponds for 25$, and I dug my first cellar at 14.I both stammered and had dyslexia but by time I was 16 both had receeded 90% and my DR and parents were convinced that yellow dragon as I called it was responsible,everytime I pass a yello dozer I give it a smart,sharp military salute, and say Thanks good Buddy
The main diesel engine is so big it takes a 2 cylinder engine (pony motor) just to get it to fire up and run !! This videos audio doesn't even begin to tell just how loud that little pony motor is !!! First time I heard one fire up I was like WTF HOLY SHIT LOL
Long be for I became a commercial ,and later a task vessel captain, I operated D 6 dozers in spring valley,and,suffering,n y back in 1966 ultimately graduating to the then new D8 h hydroxide ,finish grading the st.Thomas,virgin islands airport to accommodate the new 727 pax aircraft . I started flying when I could not get in the operating engineers union . Those caterpillar days were a w/o fearfully time in my life .thank you caterpillar corp for such fine machines !
where I live there used to be a lot of those old machines around, the coal mine stripe pits being as they were tearing up the land. The mine companies made a bad name for themselves by leaving open pits and junk when they left. Now all we see are the ghosts of the machines gone past.
Yeah the older stuff is certainly getting less common, but there is quite a bit of enthusiasm for the old machines, so lucky quite a few are getting saved luckily 👍
Should've tookhis foot and pushed that decompression lever up and let that motor spin afew minutes and build up some heat she would've cranked alot faster lol
That is what's called a push cat it is set up for pushing scrappers and another cat will push on the back on the back it's called a push block the blade on the front is some home made p.o.s. cat makes a front blade for pushing that has cushions build in it just like the back I spent most of my career working with push cat's the D9L and the D10N made the best push cat's it was the way they steer made them very fast the 9L being a little lighter made it a bit faster..
he's not doing anything to the trailer extra wood is put down on the trailer before the machine is loaded so spinning on the trailer doesn't rip the wood up on the trailer itself
That dozer came with a cushion block instead of straight or U blade. For pushing scrapers. This machine was same as one I ran on Trans Alaska Pipeline on Gobblers Knob. This unit would have a strong final drives as there was no ripper on it.
@@AlaskaDanger-jf6ti you are spot on mate ,that’s why we got her no hydraulics no rippers !, they destroy tractors! in wrong hands.That old D9 is now the rear tractor on our Quad 9 👍
Where did you get the film extra "Old Man with Stick" Should have given him a credit for his performance! Pity people like this no longer exist in real life in England any more.
+Worcester Exchange Thanks for the comment, glad you liked our film "extra" !! We are based in Wales so there are a few of us "real" men left, but originally he was from your neck of the woods if your from Worcester?? Cheers
I used to volunteer at the Antique Gas and Steam Engine Museum in Vista, CA, and we had one of these. I never worked on it--I was a steam guy--but I remember seeing on show days they'd always find a tiny girl and have her drive it in the parade (with an operator next to her at all times, of course). I just loved the way the pippy pony engine would make way for the ka-chunk of the big diesel. Starting up a steam tractor is a comparatively quiet process, at least until we get to testing the safeties, or somebody starts an argument about which beer is the best.
Actually common on older machines. I had a 50 hp International D8 that had the same set up. A very cool machine. (until I ran over a nasty wasp hive one day)
In the cold country, you could use the pony motor to warm the engine some, it uses the same motor oil and coolant systems, at least the old D7 I worked with at a mine in Alaska did. But I was a lot younger then and I don't have a pony motor to get me warmed up and started so I left the cold country.
Thats awesome, you don't see so many these days doing a days work now unfortunately , still a great machine, but technology moves on I guess!! Cheers 👍
I ran them in Southern California. There one strong dozer and easy to operate. Mine had a hydraulic tilt blade and good ripper on back. Loved it, but of course a new D10 with AC cab is also nice. I did a lot of rock jobs with it. It pulled out boulders and pushed them larger than the dozer, took some work but the dozer never broke.
Happy days, i was a mechanic/fitter back in the 70s for a cat dealer.
Man those D9's are HUGE!
I dont know why i came back to see this video for the 3rd time. Its really fascinating
Always welcome to watch a forth 👍👍
I learned to use a dozer on a Euclid C6 with a rope lifted blade. Very noisy GM 6 cyl when you take your foot off and call up full power but a wonderful machine. I.was 19 then
A D 9 G is a good old tractor. It will run for ever. The RPMs are low, and the horse power is reasonable. The D9H is another story. They upped the RPMs and increased the horse power. The H engine will run for 7,000 hr (more or less) then it will need to be overhauled, and most likely need to have the block cut for a spacer under the liner. That is a 1 or 2 time deal, then you will need to cut the block into the water jacket and install a Z insert. After that, you throw the block away and start new. The D9G will just keep on chugging. They also have a magnetic oil strainer on the inlet side of the transmission oil cooler plus another one before the transmission pump. The H has only the one in front of the pump. If you loose a power train component, you will also have to change the cooler, every time.
I've never seen that kind of trailer unhooked before. They always have a load or empty, learned something new, thanks.
As they say you are never to old to learn!! Glad the video was of interest.
Thanks

Didn't hurt the decking on bit...
ive seen a wood fire under the oil pan in video . Fire under the machine with the pony motor!! This girl started happily
Re-Ring it and ur donkey or pony would last a lil longer!!!! I bet that dozer has better than 40,000 hrs. Hard hours!!!!!! Great video!!!

why unhook the lowboy trailer and not drive off the front... turning the thing sideways wrecking all the wood for why?

I drove a D7G when I was 14. My folks were building their house and the guy was digging out for the pool, and I was riding around on my little dune buggy; he says, "I'll let you drive this if I can drive that"! I did three or four scoops with him on helping then he let me do a couple by myself!!
It was like watching a prehistoric dinosaur walk back into the woods!
Slow and steady, knowing he owns the woods and not afraid of anything!
EXACTLY !
Afraid of nothing but a track rolling off to the inside on a steep grade but the tracks looked decent on that ole boy so he should be able to walk pretty proudly I would think
10/10 placement on that caution light behind the fairing on the semi.
So it's visible from the rear as it should be.
Never heard the term "donkey start" before. Now I understand. What happens when the starter motor won't start? lol Looks like a lumbering giant from yesteryear for sure.
Cheers from Louisiana.
I always knew them as pony motors
Donkey engines here in the UK
Man do I remember those days, as a kid sitting on the heavy equipment with my Dad starting the caterpillar road graders and bulldozers , thanks for the memories.
I grew up around big equipment...we had a D9 Cat...I remember watching my Grandad burn the mud off the tracks when I was little.

After reading through many, many post. Piecing it all together you guys got it pretty much right. But first big mistake was he didn't use the compression release at all. That's the lever on the dash support by his right foot. You can see the control rod going to the head. 1st You turn the lever with your hand to release the compression before you do anything else. Next I didn't see him look at the oil pressure gauge at all. Sometimes it takes 30sec to a min to get the pressure up. After engaging the pony motor clutch and the oil pressure comes up then you kick the compression release with your foot to engage it followed by adding fuel if it's not to cold.
As far as the trailer goes I looked at the video over and over and can't see where any damage was done to the wood at all or the trailer. If you look you can see they put plywood down before they loaded the Cat. Even after the plywood got tore up during the 90 degree turn it looks like it survived well enough to keep the grousers clear of deck.
Detaching the goose neck put the front of the trailer on the ground making it more stable reducing any twist on the frame. If you look at the video you can see it looks like he may have dumped the air on the rear axles as there was very little twist or movement as the Cat point loaded the side of the trailer. I think I would have blocked under the frame to the ground in a few places and a few more for the ramp but it looks like it fared very well.
Now then for all you pretty boys that wax their trailers you need to look up some videos of cross country pipeline moves on the back roads of Pennsylvania. Most of the moves are side loaded for speed and efficiency. I've even seen two side booms loaded side by side with one boom down toward the front and one toward the back. Yes it wasn't legal but that's the way it was done. They make square turns on back roads at a T intersection that I could take all your money that it couldn't be done. Road drivers. Ha!

The old man is prime example of what u look like after u operate one for 50 years.try a td 20 .that is a machine..
I do and it was. UD start.
Where is he headed? Anyplace he wants.
Back in 86, Grants Pass, old 38 stuck out in the woods. First job after diesel school. Pony would`t stay running. Spent two days in rain. No luck. Worked on pony carb whole day. Boss yelling. Wasting time. Finally got pony good. After many, many tries, finally got main running. Boss very, very quiet. Never yelled again.
Great story!! Yes the pony's can be a pain when they want to be that's for sure, the magnetos don't like the wet!!

They did a great job destroying that trailer.
Operated some highly modified D9’s in Greenland in 67. Stretched frames, 55 inch wide track pads, some had 600 gallon nose tank, 300 gallon belly tank, and a 150 in the rear. Others had 14 foot wide blades.. dragged some very, very heavy and long loads over the ice cap. YT search Camp Century to get a view of some of them at work.
Will do. Thanks.
Geo Thomas we didn’t have any roads
Ok I've ran an old 1957 D7 with a Pony Motor never heard them called Donkey Start why not use tires and drive it off the front and keep from tearing up the trailer
Hghfuh
What a sound!!Australia 🇦🇺
I can pretty much guarantee you ain’t sneaking up on nobody ridding on that monster. :)
what a treat to find this channel.I loved those monster yellow giants. My pop and an uncle bought an army surplus cat dozer in "46.Their idea was to dig cellers in WNY state, tiny town south of BFLO.Mty older bro, a cousin and I had the job to paint it yellow,sort of yellow.I was 10 they were 14, what a summer we had.They had figured how to start the monster altho we were were told ,on pain of decapitation,to never start if unless an older cousin was with us,Who follows directions????WE had turned my grandfathers acreage into our 40 acre playground, after watching pop and uncle digging a few cellars we figured nuthing to it so we dug a pond one day.WE were grounded for a few days but by time my bro and cousin were 16 they were digging cellars and ponds for 25$, and I dug my first cellar at 14.I both stammered and had dyslexia but by time I was 16 both had receeded 90% and my DR and parents were convinced that yellow dragon as I called it was responsible,everytime I pass a yello dozer I give it a smart,sharp military salute, and say Thanks good Buddy
Great good news story ... thanks.
The main diesel engine is so big it takes a 2 cylinder engine (pony motor) just to get it to fire up and run !! This videos audio doesn't even begin to tell just how loud that little pony motor is !!! First time I heard one fire up I was like WTF HOLY SHIT LOL
you should be wearing a hard hat, just in case it rolls over on you
thatallredheadude
If it rolls over the hard hat wont do shit
Your still dead
Brings back memories with my dad putting .me in the seat in the coal fields of pa. We called the starters piney morters
You sure they wasn't called poney motors
Loved the old boy in the hat. I bet he has some stories.
Long be for I became a commercial ,and later a task vessel captain, I operated D 6 dozers in spring valley,and,suffering,n y back in 1966 ultimately graduating to the then new D8 h hydroxide ,finish grading the st.Thomas,virgin islands airport to accommodate the new 727 pax aircraft . I started flying when I could not get in the operating engineers union . Those caterpillar days were a w/o fearfully time in my life .thank you caterpillar corp for such fine machines !
What a sight..I operated a 9g over 40 years ago it brought back many memories. Thanks for the memory.
That old timer with the cane is re living some memories for sure i bet he could run it better than anyone involved with this video
oh yeah
Blade sold separately ,
where I live there used to be a lot of those old machines around, the coal mine stripe pits being as they were tearing up the land. The mine companies made a bad name for themselves by leaving open pits and junk when they left. Now all we see are the ghosts of the machines gone past.
Yeah the older stuff is certainly getting less common, but there is quite a bit of enthusiasm for the old machines, so lucky quite a few are getting saved luckily 👍
Should've tookhis foot and pushed that decompression lever up and let that motor spin afew minutes and build up some heat she would've cranked alot faster lol
Where is that going? are you releasing it back into the wild?
fastst1
Lol yes!!, this being a big Cat we thought it unfair to keep it caged up so we have unleashed it into the wild!! :-)
Reply ·
fastst1 ok dude you killed me with that one 😂
made me laugh...............wb
fastst1 i was wondering that too.
maybe the donky blade went in the woods allready....lol
fastst1 ** and after ruining the trailer ...perhaps its going to push dirt without a blade. lol.
I wish I had one like that with a blade and ripper sitting out side my house.
Bottom line , a great piece of macinery!! This old iron lasted for a long time!!
Surely,the flashing light on the tractor should be IN FRONT of the aerofoil?
Some have them fitted like to warn drivers approaching from rear, there are probably warning lights to the front.
Yeah there's other flashing lights...
That is what's called a push cat it is set up for pushing scrappers and another cat will push on the back on the back it's called a push block the blade on the front is some home made p.o.s. cat makes a front blade for pushing that has cushions build in it just like the back I spent most of my career working with push cat's the D9L and the D10N made the best push cat's it was the way they steer made them very fast the 9L being a little lighter made it a bit faster..
he's not doing anything to the trailer extra wood is put down on the trailer before the machine is loaded so spinning on the trailer doesn't rip the wood up on the trailer itself
Great to hear from somebody who speaks some sense!! Thank you and yes you are completely right 👍👍👍
Why the fuck not just drive it off the front the way the Machines facing 😭😭😭
That dozer came with a cushion block instead of straight or U blade. For pushing scrapers. This machine was same as one I ran on Trans Alaska Pipeline on Gobblers Knob. This unit would have a strong final drives as there was no ripper on it.
@@AlaskaDanger-jf6ti you are spot on mate ,that’s why we got her no hydraulics no rippers !, they destroy tractors! in wrong hands.That old D9 is now the rear tractor on our Quad 9 👍
Where did you get the film extra "Old Man with Stick"
Should have given him a credit for his performance!
Pity people like this no longer exist in real life in England any more.

I used to volunteer at the Antique Gas and Steam Engine Museum in Vista, CA, and we had one of these. I never worked on it--I was a steam guy--but I remember seeing on show days they'd always find a tiny girl and have her drive it in the parade (with an operator next to her at all times, of course).
I just loved the way the pippy pony engine would make way for the ka-chunk of the big diesel.
Starting up a steam tractor is a comparatively quiet process, at least until we get to testing the safeties, or somebody starts an argument about which beer is the best.
When your engine is such a beast that it takes a starter to start the engine that starts your engine.
Actually common on older machines. I had a 50 hp International D8 that had the same set up. A very cool machine. (until I ran over a nasty wasp hive one day)
Jet aircraft still use this method for large engines. Electric starter/generators are typically found on small ones though
In the cold country, you could use the pony motor to warm the engine some, it uses the same motor oil and coolant systems, at least the old D7 I worked with at a mine in Alaska did. But I was a lot younger then and I don't have a pony motor to get me warmed up and started so I left the cold country.
I remember in 1984 there were still D9G Pushcats in operation in Southern California
Thats awesome, you don't see so many these days doing a days work now unfortunately , still a great machine, but technology moves on I guess!!
Cheers 👍
I ran them in Southern California. There one strong dozer and easy to operate. Mine had a hydraulic tilt blade and good ripper on back. Loved it, but of course a new D10 with AC cab is also nice. I did a lot of rock jobs with it. It pulled out boulders and pushed them larger than the dozer, took some work but the dozer never broke.
In Georgia a company I worked for still uses D9 push tractors. Old girl runs like a top
