Self Leveling Loader on L & M series tractors

[Fallon]

You bet!

Yes only when on. I can see the difference. It isn't much, but I guess if you are a professional operator it would be nice to be able to turn it on and off as needed for a type of work.

I can bang it with the self leveling on.

I also think Bigpuddie may be correct...I just havent tried self leveling something as I move the FEL down. I never really noticed...mostly grapple and dirt work thus far...which means I am manipulating the curl and not letting it self level anyway. I "feel" like it doesn't self level on the way down, but maybe others can go test their machines and tell us. Mine is an hour away

I dont think it has KSR, I havent noticed it adjusting the FEL on bumps. I also never noticed it in the specs or in my research. I thought that was only on Skid Steers?

KRS is an option on the M series. Pretty darn sure I didnt see it as an option when I got my L4060 a couple years ago. At any rate it's a separate system from the self leveling systems.

It's just a pneumatic shock absorber. There is a T in the loader lift circuit with a solenoid on it. There is a tank ontop of that with air in it. Probably in a bladder or something.

When the valve is closed it acts normally. When opened the air compresses & absorbs motion somewhat as the loader bounces. Generally makes for a smoother ride when cruising around with a load on the loader.

It would likely cause erratic behavior when not traveling & using the loader for digging or what not. Things generally being squishy when hydraulics should be solid.

Most hydraulic accumulators use nitrogen as the compressible gas for cushioning. The amount of cushioning can be varied by the pressure of the nitrogen. Having a solenoid valve to isolate the cushion would be handy for when cushioning is not needed or desired. I would think cushioning would be very handy to reduce tractor and loader stress when gathering bales out of a rough field for example.

The M59 has the hydraulic self levelling and it works ok. I generally only turn it on when running the forks. I don't like it for loader work it does seem to slow down digging a bit.

I prefer the mechanical systems - the hydraulic ones seem to lose the level position and have to be adjusted regularly between cycles
