L6060 Power Steering Issue

[Fallon]

And the rear remotes being garbage is normal. I have 3 rear remotes on mine. They have put a total of 7 on mine trying to find decent ones. I have 1 for my toplink that takes half a day or so to leak down & that's the best one of the 7. Some have let my sidelink leak down all the way in under an hour. I've heard from many others that my experiences are not unique or unusual. Front loader valves are fine & it stays put for weeks at a time. Their rear valves for their premium tractors are just trash.

I've kind of given up at this point. I might get a piloted check valve for my sidelink but that kills float. There is also the option of a solenoid valve to keep float, but is a bit more complex.

Things must have deteriorated since I bought my M6040 in 2009. All my hydraulics - FEL & 3-point - will hold their raised position for months.

I no longer leave anything in the raised position. I came around the carport and walked right into the raised grapple. I screamed so loud and used such language - the lawn curled in stark fear. Large bruises but no blood.

Mine leak down in about an hour too, less if I have something heavy in use. I still say this is not right! It may be normal on a new Kubota but it is not right. It is the norm because they purchase poor quality remote valves and install them on their Premium tractor. If all their tractors do it then it is the norm for them. BS for a Premium tractor.

I very much concur on being normal but not right.

I stuck a clock for timeframe on the flail & grabbed some sad sagging photos last year.

Mine does seem to turn left earlier than right at the stops, but it's not that pronounced. I have to lean on it pretty hard either way. L4060 steering - YouTube

Mine seems a fair bit tighter than yours though. Yours does seem pretty loose to the left. Not sure what to make of that. I wouldn't think anything of it if that were the only symptom. Tractor & HST steering is always sloppy. It doesn't need high speed handling. But it sounds like yours new one may be a fair bit sloppier than mine e with 500 hours on the clock.

Mine doesn't do that. Left or right it stops and I can hear the pump groan if I try to go farther. It's a solid stop.

Hydrostatic steering will always have some creep. Parts in the hand metering unit need to have clearance or they will not move. Vehicles have power assist with a direct mechanical link. Parts are built with a tolerance so some HMUs will creep more than others. The WSM does not give a limit on steering drift but your dealer should be able to verify if yours is within limits. I have 4 Kubotas with hydrostatic steering and creep on my L6060 is worst.

Thanks for that video. I can see yours basically does the same thing. The only difference may be in how much pressure is applied to make the wheel continue to turn. On mine it is quite easy to the left and very hard to the right. From your video it looks like yours is also easier to the left but it appears to take a fair bit of pressure to do it. I guess the only way to compare would be to put some sort of pressure gauge on the wheel.

It's odd that johnnyvol reports his does not do the same thing and MHarryE reports that all of HST tractors do it, with the L6060 being the worst.

MHarryE also reports that the WSM does not provide limits on steering drift. So how are acceptable limits determined?

Is a very interesting subject. Don't take this wrong....

Why would you continue to turn the wheel if you were turning in what was to be the heading you wanted to turn into?

Was it just because you noticed you could? Or because you thought you needed the tractor to turn more?

I am not getting the discovery aspect of this discrepancy.

In my first post I describe what happened to prompt this thread. Essentially I was traveling down a straight road that had a typical crown and found that I needed to keep adjusting the steering wheel to the left in order to keep the tractor in a straight line. If I did not keep turning to the left the tractor would have run off the right side of the road. I've never experienced anything like this before and thought it was a flaw. But I am hearing this thread that it may be normal.
