Good morning, I just purchase a 656 Hydro. In both high and low range the hydro jumps out of motion in the forward motion. I can basically touch the lever and it jumps back in, also if I hold the lever with pressure with my hand pushing to the inside it will not jump out. In the reverse motion no issues. Seems to be strong even in forward high just jumps out. What are your thoughts. Thanks in advance for your help.

Look down at the side of the hydro leaver. About halfway
down you can see the in and out valve,the bottom of the
leaver is the rail (for lack of a better word)that it pivots on
(front to back) mine will jump out of reverse and I just put
a block of wood on the dash to keep it from going wide
open in reverse.

There is a valve operated by the side-
side movement of the hydro lever when
it's in the neutral position that creates
a ''dead spot'' so the tractor doesn't
move/creep in the neutral position. The
mechanism that operates that valve is
worn and/or out of adjustment causing
that valve to be actuated when the hydro
lever is in the ''forward''position. It's
possible an adjustment will help, but too
much change will shift the problem from
the forward to the reverse side.
Likely, replacement or repair by welding
up the up the worn parts and grinding
them back to shape will be needed. Having
a factory service manual is essential if
you are going to repair it yourself.
As always, BE CAREFUL when working with
the hydro control mechanism that the
tractor doesn't move unexpectedly and
crush you or run over you or bystanders!
