Electric Tractor Coupler Construction Part 01
HTML-код
- Опубликовано: 1 авг 2023
- Progress continues on the electric tractor project! I strip out parts from the original tractor components to build a coupler.
Please click SHOW MORE!
On the International 300 Utility tractor, there is an input in the transmission for both the wheels AND the PTO (Power Take Off.) That's accomplished by one shaft inside the other, with the outer one (PTO) connecting directly to the clutch cover plate on the flywheel, and the inner one (wheels) connecting to the flywheel through the clutch.
To be able to power BOTH with a single electric motor and keep it fairly simple, I plan cut the splined parts out and then weld them together and to a LoveJoy spider coupler and then to the motor.
In the next video, I'll measure the spacing needed, create those spacers on a lathe, and cut the components so that they will be concentric and ready to weld.

Great to see this project back again. Very best of luck with it.
looking forward to see how it goes forward!
Hey Ben long time no see! Good to hear you're working on it again.
That looks like it going to work great .
Excited to see this project coming along
Good work. Making progress.
Brilliant stuff!! can't wait to see the end product!😃
As usual, good stuff Ben. I've been wondering what became of the tractor conversion project. (But full disclosure: I found myself yelling at my screen, "Don't hit the thing directly with the sledge. Put a block of wood on top. 😉) Keep up the good and interesting work.
I did an electric tractor conversion and had to install a flywheel to get it to run nice and smooth. W/o a flywheel I would get huge spikes in amperage when you jerk any kind of movement. Hope this helps
I was wondering what was happening with the tractor
No, I may just be a lazy city boy here and I have no idea what I’m talking about but I think the concept of tolerance is a thing and it seems like you’re throwing it out the window great Contento tho
I may have missed something, but didn't you want to have the ability to drive the PTO without moving the wheels? Or will those decouple elsewhere?
With this type of setup, the PTO can spin without moving the wheels by simply not having the tractor in gear.
The PTO has it's own dedicated control, so the PTO can be turned on and off while the tractor is in motor.
What it would NOT be able to do is have the PTO spinning, and then smoothly pull away from a dead stop.
Part of this too is just that I really want to try it out. A solid coupler is much easier to design than an entire flywheel/clutch/clutch-cover/bearing/weight-support. After testing this out, I can see if it works the way I want, or if it really DOES need the entire flywheel assembly setup.
Will the PTO be useful if the wheel-speed is directly correlated to PTO shaft speed?
Could the PTO have been driven by a separate motor or using the clutch to keep the tractor still while using the PTO?
I guess you could also just mount a motor anywhere as a PTO…

I think you messed up.. You should have kept that clutch in tact so that you can disengage the PTO or driving independently. I understand that all the extra rotating mass is an issue for "Acceleration" -- but in a tractor, you don't need acceleration at all. And all that spinning weight actually works in your favor when running a brush hog, because if you hit a stump or rock, the inertia of that rotating mass will protect you motor. Where as now-- any kind of sudden SHOCK from hitting something with your implements is going to directly transfer into the motor. So you lost two good benefits by doing away with the clutch... I tried my best to explain this in one of your past videos.. So I suppose you're just trying to get this thing built for the videos and not actually planning on using it much; which is fine
Hi Calholi,
More than anything, I really just want to get the tractor going.
I have a brand new clutch and cover and still have the flywheel. So, it's not like I'm at any loss of parts here.
I really don't want 80 pounds of flywheel hanging off this Etek type motor.
I'd like to try the tractor in this configuration and see how it works.
PTO on this tractor is independent. It can be engaged or disengaged at any time regardless of what the wheels are doing.
I also have a 13" series-wound forklift motor. That should be able to hold the flywheel just fine, but it's also a lot more complicated machining to make that happen. Frankly, even making this simple coupler is good practice for some basic machining skills.
That 13" motor SHOULD just exactly squeeze in to the tractor, but there's other complications as well.
Constructive criticism is always welcome.
@@BenjaminNelsonX I have a ford 8n converted to electric. You really need a form of a clutch as you don't have enough hands to drive the tractor, run the front loader and control forward/backward motion. My conversion was clutchless and i had a problem when running a back blade. I ended up adding another pot box attached to the clutch peddle so that my foot could control the forward/backward motion. It is a bummer to loose the live power aspect for the pto but livable
@@timothychapin8879 Keep in mind that power ALWAYS goes to the PTO on this tractor. It is engaged or disengaged with a handle to the right of the operator. The PTO is UNMODIFIED compared to the stock tractor.
@@timothychapin8879 You might be right about needing a foot-operator throttle. I really want to try the tractor and just see how it goes.
