[AT] 430V

[charlie hill]

Spencer, have you tried loading pressure against it in the other
(opposite) rotation?

I am still of the personal opinion, if it was mine and stuck that tight,
I'd want to see what's going on inside it.  Even if you get it to break
loose aren't you going to be worried about the damage that might
be done if you start and run it without knowing exactly where and why
it is stuck?

Charlie

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.
