M7060 hicups

[Raul5452]

Kubota owners please help. With any implement hooked up when I raise the implement to any working height the hydraulics keep resetting. As if it lowers a bit and then it raises back up to it's proper height. I spoke with dealer mechanic and he said I need to fix a lift assist cylinder leak. I fixed the lift assist cylinder, the top link hydraulic cylinder, and a hydraulic hose going to the hydraulic pump. Not all were leaking at the same time . It was one of those things that you fix one then the other acts up. Anyway no more leaks anywhere. But the hiccups are still there. Very annoying and I'm afraid it might damage something. Anyone out there experiencing this problem ?

No, I don't own one BUT I think I know what your problem is. Very few dealers these days seem to know anything about the Draft Control aspects of 3pt hitches. I assume (bet actually) that you have a Draft Control system on that M7060. Go to your owners manual and see how you disable the Draft Control. Probably just a lever positioning. Your problem will very likely go away. I've seen the exact same symptoms on other tractors. Minus all the leaks ! What on earth caused all those leaks ?

I have an M7060 and it does have draft control. Perhaps the OP can check the positioning of his and, hopefully, that will solve the problem.

If either or both lift assist cylinder piston seals was leaking oil should exit top hose on 1 or both cylinders when 3 pt is in raised position. If no oil exits either hose I'll guess leaking rockshaft relief valve or control valve mounting seals.

Thank you jwr but I have tried moving the draft control lever to different positions and the hiccups continue. As for the leaks, the lift assist cylinder seals just went bad around 1500 hours. Ordered a seal kit and put them on . Problem solved. The top link , the end cap loosened on me. Tighten it up good and tight, problem solved but I've already replaced seals on it a couple of years ago. The hydraulic hose , I hit a stump about two months ago in the tall weeds and grass . It tore of the select control valve guard . I think the hose got scrapped and just took a while to start leaking. I do alot of work for customers in my area. Mowing vacant lots, pastures, some brush clearing and dirt work. I purchased the tractor in 2017 and I'm fixing to hit 4000 hours this year. It is definitely earning it's keep.

Any other ideas out there ?
I'm going to try readjusting the draft control linkage in the back .

Unless you need Draft Control for plowing, etc. I would disconnect/disable it totally.

In my limited experience with this problem, it has been either leaking cylinder(s), or the the 3-point valve itself is leaking. My experience is with JI Case tractors and there were ball check valves built into the 3-point control valve that would leak or get crap stuck in them. No experience with Kubota valves.

Well Gentlemen, I readjusted the draft control linkage. First I lengthened the linkage and the hiccups got worse then I shortened the linkage shorter than it was set at by 3 threads and the hiccups quit. Went to work the next day and it started again. Not sure if I want to remove parts to get into the rockshaft control right now. Super busy season. I'll have to tackle this in November or December when work is slow. Thank you all for your input and help. But if anyone thinks of anything please let me know.

Understand -- you got work to do. I still think it is draft control related. Let us know when you get back into it. Good luck.
