135 position control lever not working.

I'm new to tractors. I recently bought a 135. I didn't realize it had 2 levers to control the 3 point hitch. The regular position control and the draft control.

The draft control works. It raises and lowers the hitch. But I can't get it to stay in one position easily. I guess it's working as it's supposed to.

The position control lever itself was broken. So I welded it back together but it doesn't do anything. It feels like it's not even connected to anything. It's quite easy to move.

What might be the issue and how can I go about fixing it. There doesn't seem to be a lot of picture online of what's under that top cover or what may be the problem.

Any info would be great thanks.im guessing my best bets to take off that top cover and see how the mechanism works exactly.
 
Sounds like top cover internal linkage trouble. DON'T remove the lift cover until you read a service manual, there's a linkage roller to be removed first. Used to see that mistake made a lot when I worked at the MF dealer, mostly happened on the state highway mowing tractors..
 
Dieseltech is absolutely correct about the roller and the workshop manual....preferably the genuine MF one. To
start any removal process you will need to remove the RH side cover. Before you do this drain the oil to the
level of the bottom bolt. With the cover removed you will see the 'vertical lever' coming down from above and the
pump lever above the oil level. Operate the DRAFT lever and you will see that the pump lever is allowed to move
rearwards when the DRAFT lever is raised. When the DRAFT lever is lowered the pump lever is pushed forwards.
Place the DRAFT lever in the raised position and operate the POSITION Control lever. If everything is working the
pump lever should respond in the same way as above. A further check is to set the POS lever at about half way and
have an assistant lift the 3-point linkage by hand. As the linkage passes through the corresponding halfway point
the pump lever should return to the approximate central position which is 'NEUTRAL'. Lowering the POS lever
should move the pump lever forwards into DISCHARGE. If none of this happens then there is a problem within the
cover linkage. There is a very fine spring in the linkage which can either break or rust away and this can cause
problems. Familiarise yourself with the system from a manual first. We are here to help you further.

Ok thanks a lot.
I'm waiting on some brake parts so I can get the brakes working. Also waiting on the weather to warm up here in Canada before I wanna get out there and spent some hours working on it. I'll update in a few weeks. Thanks again.
 

I am having a somewhat related issue. I am trying to rebuild the ORIGINAL quadrant assembly of my 1967 MF-135 Diesel after finding out that the total [New] replacement assembly was not matching the one removed. I am attaching a photo of the two assembly side-by-side hoping that some experience person can advise whether the configuration of the roller /shafts (on the one on the left) are correct. I attempted to annotate the Photo for clarity.

PS. the hydraulic pump is a MK-11 with pressure control.

(quoted from post at 19:35:39 03/09/17) It look's like your replacement assembly is for a unit without pressure control.

Yes, I share your observation but the vendor didn't infer that major detail when advertising. I would NOT be using the new assembly. My problem is resolving the correct position for the rollers on the "rebuilt project" [left photo]. While the inner shaft/roller (Position) is keyed and foolproof, the outer shaft/roller (Draft) is pinned and can be rotated 180 degrees from the position shown in the photo. Therein lies my problem.............Need to be sure before I install.

Details... details.. lol.
Actually i think you have it 180 off but not sure. I don't have one handy to verify but maybe one of the other guys do or know off hand. Sorry i can't be of more help.

Thanks anyway ! Hoping someone versed with the configuration can render some assistance. I want to avoid making the same error as a previous post where in was probably installed incorrectly causing a catastrophic splitting-crack of the center housing on a similar tractor.
 

Howdy! I hope I'm far enough here in Finland if you crack your central housing. Anyway in 9. picture of my page there is a lift cover upside down and some numbers on it:

http://haapasalontila.fi/MF565linkage.html

I know that looks different from 135 cover, 135 has more parts attached to it and part 1 is different. Anyway you should find corresponding parts in 135 cover. After you've installed the levers and position lever is in transport position: When draft control lever is all back position, part 1 should be on the right in the picture. When draft lever is moved on quadrant, part 1 should move to left.

I think in your picture the rolls that draft lever moves should be in the same direction in both assemblies.

To simplify my issue [still to be resolved], I have captured an overview Pic of the respective positions of the Quadrant levers as it relate to rollers. The inset to the lower left displays the location of the Draft Roller [Option-1]. The inset photo to the lower right display the location of the same Draft roller [Option-2] when I rotate the shaft 180 deg in the lever and re-insert the fixing split pin. the question is - which is the correct way ? left or right ? .
The Position lever is keyed and can go on one way only.

Left is correct.

Thank you very much for your advice.
Unless someone challenges your experienced opinion in the next few days, I am going forward with the re-assembly with much more confidence.

So, did this work for you? I'm in the same pickle.
