(quoted from post at 22:40:15 04/30/20) If you need to get it down manually until the service manual comes, just unhook the hose on each lift cylinder, fluid will come out as it lowers so you may want to catch
it in something


After investigation research and some planning, I did decide to let the arms down by opening the lines.

Opened them up...nothing, not even a weep of fluid. Then pushed down on them with the lines loosened. They don't go down by themselves...so I used a small tractor with forks...took a lot of force to get them to go down. Raised them up under 1135 power and then forced them down again with the lines tight. They went down, but do not drop down by themselves.

I've been researching all the ins outs and tests for the hydraulic system. Very complex and comprehensive.

This little test might suggest something? Could the cylinders be that stiff? Not likely there's a relief in the line...as the hydraulics can be pushed down with about 500-1000#

The hint that it''s the oscillating valve is a good guess, but I'm not tearing the top off the box to see if that's correct.
This push down test of mine should suggest something.

Farmer Ben is disc harrowing now, but will need the 3 point at some tasks...

Rock shaft sticking.

I had lift cylinders on an 1130 stick
this bad before. Had to use loader to
"pop" them but seemed to work ok after
that. Would be real stiff first time
moving them in the spring if not used
often. Not sure whether it was in
cylinders or in the rockshaft. Alot could
be learned with plumbing a gauge in the
line on one of the cylinders, and seeing
if it makes pressure when pushing down on
them. If it does- valve problem. If not-
cylinders stuck, or rockshaft bushings
seized up maybe.

Push it down, pull pins from cylinders. Lift on the links with small tractor. If it goes up easy, it’s the cylinders, if hard then rock shaft.

Managed to jerk up and down on the arms and the left cylinder seems a bit sticky, but after a few cycles, it will go down by standing on the arms...

I expect after even more cycles, will work better.

glad I didn't start tearing the lift cover off...

Thanks!

Yep, one cylinder sticky.

thanks!
