DIY Mechanical Self leveling loader

[TractorGuy]

Got to searching around and found this instruction for adding a Hydraulic leveling valve to a loader. It is on the Rhino site but I don't see where they make loaders.

My JD 245SL Loader has a relief valve that dumps to the sump (transmission case). One more line to disconnect when removing the loader.

I have heard that the hydraulic leveling valves are not so good? Just wondered if anyone has had any experience with them? This would be installed on a NH TN75 with Stoll HDPM8 FEL.

Never used one my self but I've heard several times that they lose position over time and are not that accurate.

The hydraulic self leveling using two small cylinders connected in parallels with the curl cylinders, like I've shown on the first posts, seems to work very well and haven't heard any complains.

I am not sure what the excitement is for a self leveling loader. I have one on my Kioti and I have been trying to determine how to get rid of it. I wonder if the loader arms are strong enough once you eliminate the linkage between the rear pivot and the bucket cylinders.

This topic caught my attention...

Since completing my forks, and finding them on the loader 95% of the time, using pallets and IBC totes for more and more things, I often think that a self leveling mechanism would be beneficial to me. I've gotten decent at simultaneous lift/un-curl stick modulation, but it's still awkward.

The potential for curl function over-travel when raised and full curl extended hadn't occurred to me until now, a valid concern. Not sure how to work around that mechanically, at this point. Don't most mechanically self levelers have double linkage at the bucket end? I've never studied them closely.

My old Kubota B-21 - three tractors ago - had mechanical self leveling and I really liked it. I never had a moment where I said "how do I get rid of this?" It saved my but a couple of times when I was tired after a long day and a moment of distraction would have spilled some of my load in my lap. Now I have a '90 Ford 545C with a Case Model 33 backhoe on it and it has a mechanical-hydraulic self leveler that seems to work well. It only works in when lifting though so if one lifts a load, say to get over an obstacle, then lowers the load one needs to manually level on the way down to prevent spillage.

I think you could also get a self-leveling hydraulic feature if a person mounted a short hydraulic cylinder between the oscillating front axle, and the tractor frame. That would force the pivot point on the front axle instead of pivoting the loader. A person would have to have a float position on the hydraulic valve though so that it could be free to float when not needed for self-leveling.

I've read this post several times but do not understand how a cylinder on the tractor axle would be used in conjunction with self leveling the loader. Can someone help me here?

My understanding from BrokenTrack's post is that he is thinking on side to side self leveling, like some telehandlers have that tilt/rotate the entire for attachment left and right.

Andrew Camarata's telehandler has this feature on the forks. Looks handy for uneven terrain or if you're lifting a steel beam for a roof, you give the proper angle right away.

The only reason this works on a telehandler is because both axles pivot. If you tried the same on a tractor with the rigid rear axle, all you would do is pick up one of the front tires. If you did this with a loaded bucket up high, you will tip over.
