im sorry to say, but you´ve got reverse ackerman steering. toe in on turns instead of toe out on turns... it´ll drag the front tires and be real jittery with that setup. the centerline of the rosejoints of the draglink and the spindle has to form a line that meets at the center of the rear axle. then it will toe out on turns and the front tires will track right and not drag... that said, the machine looks f-ing cool man! i love the piston shifter and the diamond plate and the real wide front tires. subbed and liked :-)
I think the bare steel look will be cool on that tractor. My cousin did something similar with a mini bike gas tank, after he ground the paint off he sanded the metal with 120 on a DA to make all the grind marks more even. It came out nice
Your project looks great. My only tip is that you should not be concerned with maintaining back pressure or exhaust tube lengths because it appears that you are not going to run them into a collector. So the least amount of bends in the exhaust will increase flow efficiency, thus improving your engines performance, provided you can adjust you carb to compensate for the increased air flow.
I think the whole back pressure myth is a confusion of flow vs velocity. it's more about pipe diameter...if the header is larger than the port, exhaust gasses slow down and linger causing turbulence and heat... in high school for a project I made 3 identical headers for my mildly modded go cart engine of different diameters... I found that a header slightly smaller than port dia (1" port with 15/16" inside dia header) seemed to be most consistent and ran a bit cooler than port matched and significantly cooler than a slightly larger header... I got the same results tuning the carb for each pipe as I did leaving the carb tuning constant
Instantly subbed. Top speed estimates? I'm sure the torque will get you there pretty quickly. I'm doing a diy mini car project with a 724 vtwin and subbed to see how your mower turns out.
I am building a race mower would 9 1/2 wide x 12 tall in the rear and 7 wide by 11 tall be a good tire set up? And what camber,caster,tow setting do you do?
you have a really odd ackerman angel on the steering, never seen anyone run reverse ackerman on a mower before. You might want to do some testing, or research it if its a term you've never heard of as it is vital to a proper setup!
i do releaise this this is nothing new to me i do not have a problem with this or running it like this its always worked just because a book or online says is perfect this way does not need to be that way try experimenting & find out what works

Love that front end set up nice job.
That thing is coming along nicely Mike. Thanks for the videos. Really enjoy watching them...
very nice build. I love the look of the front tires streched.

Looking sick man, Loving the build!
looking good keep those videos coming

there will be a collector later just wants to wait for final assembly to see how i would like it fitted

That steering is really fast. It will be scary at high speed with any bumps.

on our small track pos 30 on the larger tracks i have no idea i will do a top speed video
I hope to do something like this with my a100 wheelhorse
Where did you get your stearing and front tires from
Where did you get all of your staring components from including the square tubing to mount the the hubs to
I make them
I got a mower.....I'm gonna RACE.
GOING TO BUILD 2...ONE FOR WORK AROUND RANCH And
One to race. ...way cool.
Did you just mount the transmission upside down then ran a chain and sprocket from it?
transmission is correct
looks sweet what hp will you be aiming for?? why not a double pully clutch
stock 25hp engine & it is a double pulley clutch refer to older build video
Cheers ill have to check. I must of missed one of your vids.
Dope
I am building a race mower would 9 1/2 wide x 12 tall in the rear and 7 wide by 11 tall be a good tire set up? And what camber,caster,tow setting do you do?
yes those tire sizes are fine start our with neutral chamber then adjust after trying it as far as caster try 2 deg positive first then adjust out
Thanks so much and will that tire size combo give me to much over steer or understeer
Also what angles do.you use when you cut your front axle including the ends

Well I apologize if I came across in a demeaning tone, I was simply trying to help a fellow builder out.
no you good i understand
where did you find the internals? the cam? the billet?
everything in this motor is stock nothing has been altered
MikesBigBlock what size front tire
for racing don't you want a foot throttle or put it on the steering wheel
What size are rear tires and wheels
Luis Gaza 16x750x8 @ 8x8 rim
Where did you get the wheels and tires
bandit racing chassis
What's a good stock mower for racing?
the free ones
MikesBigBlock what size front tire
What size front tire
What is the size of front tire ???????
13x7.50-6
