m5660 three point hitch will not go up

[TangTimeMe]

I can lift them manually they will not stay up
The knob under the seat does slow down the rate a little

First thing to do is disconnect, clean, and reconnect the loader quick connects. One may not be seated properly.

To my knowledge all tractor 3 pt arms can be raised by hand with no load attached if the 3 pt doesn't have rare option of "down pressure". How long since hyd filters were changed? Does frt end loader operate correctly?

If you have remotes or a diverter valve on the tractor and one of them is activated it can stop the 3PH from lifting. Check that something isn't partially activated.

It should stop them from lowering altogether of it's closed (right turn fully).

Not if he's manually lifting the three point arms, the only reason they are falling slowly is ????? maybe resistance of the seals on the rock shaft??? As the piston didn't move, so no fluid to stop the piston, that wasn't moved anyways.

I'm lost, the title says the 3pt won't go up, but everyone is talking about the hitch going down.

First thing that comes to my mind is be sure that your draft control lever is all the way forward-down. Then use the position control to operate the 3pt hitch.

Good luck.

Had one somewhat recently same issue. Won't go up. Found draft control pivot link broken, caused position control valve to "think" that the draft control was all the way, forcing 3ph to bypass fluid so that it wouldn't build pressure. Replaced broken link, problem solved. That particular one happened due to a user backing a large (8') single spindle shredder into a ditch with a lot more force than it's designed for.

Interesting stuff. I wasn't aware that the M5660 has both the position and draft control for the 3 PH. The specifications on Kubota's website shows position only.

Is this an older tractor or is there simply a typo on the Kubota specifications?
