3-Point Issues (Won't raise load)

The 3-Point Hitch on my MF 135 will raise and lower normally with no load on the linkage. It will also behave normally with a 5' King Kutter brand rotary mower attached.

It would NOT raise (or at least very far...and even then it was the left linkage...that went the farthest up) with a King Kutter 3-Point Disk Harrow (the orange colored one) however, after one takes the disk off the linkage its fine again. Also I when I 'helped' it up (just a little bit to see if weight was the problem) , it would start to take and then sink back down again.

When the tractor was in the shop I had remotes installed...the levers that control the remotes and three point sit next to the seat and are the MF remotes acccessory that would have matched up with the tractor when it was new.

Would this be causing the problem? I am guessing without seeing my service manual, that a relief valve blew or something to that effect. I have a hunch whatever it is might be stupidly easy to fix and I'd like to try it myself.

Any guess at what the problem might be?

Weak master control spring. (Located under the seat, at tractor end of 3-point top link. (weak or out of adjustment)

Save that, possibly the draft control bump stop screw out of adjustment. (located on under-side of 3-point top cover)

Mine would lift "light stuff" but when I tried to lift anything heavy, it wouldn't raise but part way. It wouldn't lift over 100lbs with the draft control side. Now (after all the "Big Dean repairs") it raises enough weight to pull the front end of the tractor off the ground. (No parts bought. Less than 2 hours spent adjusting)

Spend the $25 and get Big Dean's CD. It covers all these issues and so much more.
