Is this it, Matt?

That's the one!

The starting M has a V8 and a second transmission that he puts in reverse to get the PTO turning in the correct direction.

As you can see at the end all he does is disengage the PTO on each side in turn.

I can't see the video, but I assume it is starting using the PTO just as I do to start Harley.
It is common sense to take a method and try it. If it fails, admit it frankly and try another. But above all, try something.

Using a flat belt pulley to pulley is a lot safer and your speeds are close.Hand clutch on the crawer would help too. Engage the crawer pulley and desengage the clutch.get the cub hooked up and running then use the crawer clutch and let it slip as needed.When it starts[IF] desengage the crawler clutch first .And you can pull start any direct drive crawler. But if you don't know what you are doing DON'T DO IT

Notice that the PTO is barely turning. He notes that the PTO is only turning about 100RPM, but from the looks of things it's even less than that.

If you could figure a practical way to gear a Cub PTO down to about 100RPM with the engine running wide open.

The reality is that it would be much more practical and less expensive to adapt an automotive type starter to the T20. Tractors of that era are often converted using an automotive flex plate bolted to the back side of the belt pulley, and the matching automotive starter.

Bonus points if you convert it to be a Coffman shotgun cartridge starter.

Did someone say something about butter in a previous post? I'll bring the popcorn, I want to watch this. Tractor to tractor with pto sounds really bad. I did see a YouTube video with someone starting a tractor wrapping a strap around a pto shaft and using a truck to pull the strap. This keeps every one away from the pto shaft. And nothing connected to the tractor after pulling the strap. Still all this is scary stuff. There is a reason farming is one of the most dangerous professions and the pto is one of the biggest reasons in my opinion. Be careful!

I worked on the farm for over 20 years.in 07 I got my arm in a grain auger when it was running. I was very lucky, 5 surgeries and 3 1/2 years later I was patched up pretty good. So much for "lock out, tag out "if you know what that means.

I do and it also means ONE key for the lock and that key must be controled by the person who has the use of the lock.

The first time I saw something like this, I wondered what the heck the point of it was. Then one day I saw one with two locks on it.

The cub PTO turns clock wise at engine RPM. The T-20 pto turns at 540 RPM counter clockwise. The cub can be started by the T-20 PTO :{_}: :{_}: because setting back to back the T-20 PTO will turn the cub engine proper direction. The cub PTO being turned at engine speed would not have enough torque to turn the T-20 engine because of the gear reduction in the T-20 transmission to give the T-20 a 540 PTO. The process of using the T-20 PTO will act like a super overdrive and thus the cub engine hasnt near enough torque to do it. In fact if you coupled the cub and T-20 with a shaft as mentioned the cub would not budge the T-20 at all. A properly tuned T-20 or any hand crank engine will fire right up with the hand crank. BUT!!! good hot mag with constant spark at proper time and properly working carburetor along with the impulse and timing set properly will aide in starting. I have a 1929 McCormick 10-20. 2 clicks of the mag choke on, third click of the mag (choke off ) its running. Very easy to start. :{_}:
