[AT] 430V

[Spencer Yost]

Thanks Tom. The tractor is a very low hour tractor, and I am very amazed at how little play there is to develop any real acceleration with the roll back-and-forth method. I have tried chocking one wheel, raising the other and shock loading that way. With the set up I just put together yesterday I can  vertically rock , from the operator's platform, the tractor  and get some real good up and down shock loading(engine hoist arm flexes a bit).   

PS.  The hoist did not leak down over night.

I have some weights from the  John Deere B I used to own, and some weights  for my Pacer that are not installed currently.   As for gearing I am using fifth gear. I did only earn a B in or physics so I may be wrong about this; but I believe 5th gear(this tractor does have the 5 speed option) on the wheel is the same thing as first gear in normal engine powered circumstances and would generate the most torque.  I would love some discussion on this. I don't have a lot of confidence in my understanding.
