Title: 825 three point hitch operation
Post by: sd825 on December 13, 2018, 12:00:21 PM
Greetings, fellow Belarus enthusiasts. I recently bought a 1995 (I think) MFD 825 to feed cows. Lurking through this site has been incredibly helpful in figuring out this tractor, but now I have a question of my own. I am running into issues with the three point. I need to use it with a round bale carrier, but I can't get it to maintain position. If it raises all the way up the top of the bale carrier hits the battery compartment. When I get it set to an OK height, it will either raise all the way up, or drop down while I'm driving - I think the issue is with draft control, but I'm not sure. I don't need draft control, just need to be able to pick up and hold a bale at a set height. A couple of problems: 1) I don't know much about 3 pt operation to begin with, especially how draft control works, so I might be doing something stupid. 2) My tractor is missing the third hydraulic control lever that the manual indicates controls the 3 pt. It only has 2 levers that control the 2 rear remote hydraulics. The only 3 pt controls I've found are the depth control lever that sets the bottom end of the 3 pt travel, and a knob (at top of picture) that I pull up to allow the 3 pt to drop to the depth setting. To raise it I have to raise the depth control setting. On my old Allis Chalmers, I just leave the depth control all the way down and use a separate lever to move the hitch up and down. Is it possible that my tractor only came with one rear remote hydraulic, and somebody before me plumbed the second remote using the 3 pt lever? I hope there is a simple solution to this and I'm just doing something wrong, but I'd sure appreciate any suggestions, insights, or advice anybody can offer!! If there are any pictures that would be helpful let me know and I can add them.

 I have a 825 and I  use the remote lever to operated the hitch.  I have 3 levers so that's how mine is plumbed.  Never have used the draft controls down by the throttle on mine.  Do you have a manual? I'd have to look in mine and see exactly how its supposed to actually work.  Maybe post some more pictures of under your cab of the spool valves and lines too them.  Maybe I can see something that's different.

Thanks Haymaker. I have a manual - it says there are supposed to be three levers, but there are only two. One is straight, and the one on the right is bent outwards, and looks like the one that is supposed to control the 3 pt in the manual. I didn't get a chance to dig into it over the weekend, but I'll try monkeying around with it some more and get some pictures of the underside. In the manual it says something about changing between draft and position control mode through the access hole under the seat, so I will see if I can figure out what setting it is on and if that affects anything.

Not sure on the 825...but... what you have should be all there is..1control lever for the 3pt hitch lever(as shown), the 3 levers you mention would likely be the 3- SCV control levers for the hydraulics. On my 8345 the draft control lever is on the front left side of the seat platform(under the seat). The rod you mention at the rear by the throttle/hyd. control is the 3pt hitch lock - hitch can be locked in the 'up' position. If memory serves... there is an adjustable sliding stop in the 3pt control mount. B.
