The little foot pedal next to the transmission shift quadrant is the decompression pedal, you step on it with your left foot, hit the starter button and release the pedal.

Some pretty cool stuff there. Thanks for the video. If you check out the pony motor on your R, you will a lot of similarities to the one on the D4 Cat.

Yes, they look very similar. I've heard that Deere got done pointers from caterpillar as they were designing the R.

I read somewhere that the JD 70 series had a problem with the splines on the flywheel getting worn from the great forces from the engine stopping and rocking forward and backword as it was stopping...
@jonelsonster28 күн бұрын
I've heard that too... Not necessarily just the 70, 720, or 730, but all the two cylinder Deere diesels. I've never experienced it though. The simple solution is to pull the decompression lever when you're sitting the engine down. Then the engine can just spin freely to a stop.
@richardskarie802Ай бұрын
We had a 730 diesel with electric start. There were four 6-volt batteries under the seat, wired for 24 volts. I wonder if the higher voltage was sufficient to eliminate need for the compression relief.
@brianrvdАй бұрын
No, they still had compression relief, but it is a tiny pedal instead of a long lever sticking up.

The 2 cycle Detroit does not have an intake or exhaust stroke so it uses the gear driven blow to blow the exhaust out and put fresh air in for the next compression stroke.
@jonelsonster28 күн бұрын
Yup. They can't run without the blower feeding them fresh air. I've heard some people say that since they've got the blower they're classified as forced induction.

I know the gas letter tractors have a petcock. I was referring to the compression release on the diesel tractors that opens the exhaust valves to release all the pressure in the cylinders. Some other comments informed me on the 730 it is a foot pedal instead of a have lever like the 720 had.

I've seen hundreds of antique tractors but I've never seen a 'Power Horse' before. Nice review of the line! For the record I'm NOT a fan of straight pipes for naturally aspirated tractors, especially the 2 Cyl JDs. The muffler delete on those does nothing for me.
@jonelsonster28 күн бұрын
There are a few guys out here that collect the power horses, so they show up at local events. But I've never seen one in operation. It'd be fun to see one in action.

I remember my grandpa and uncle had a David Brown they used as their loading tractor. They had a 55 gallon barrel on the back full of concrete as a counter weight to keep the tractor balanced when they were moving big round bales

That power horse looks an aweful lot like an Allis Chalmers B in the front, at least the tin. Any idea if that’s what same motor as a B?

I think they used a little 4 cylinder flat head Continental engine. But you're right, the sheet metal looks almost identical to a little Allis B or C.
