I messed with it a bit today, basically tried to mount the 3pt to the tractor directly and I think it"ll work.
Need to find the right spot to mount the rock shaft mounting brackets so it works right and clears the rear fender seat pan.
Also need to get a cylinder and a diverter valve or a 2 spool control valve.

I'm with tudor, as I think it's about the same stroke as the belly lift cylinder, around 4 to 4 1/2". My memory escapes me on exact figures. I never had a factory MF14 3pt lift, but I did have one of the cylinders at one time for one.

I just checked the AGCO parts books and for the MF16 tractor the hyd cylinders have the same body, piston, seals rod are the same, they have the same part #s.
That means that the diam and stroke will be the same for both mower and 3pt lift.

For the MF14 tractors made serial # 6559 and up (1/2 way through 75) use the same cylinders as the 16. Before that different ones were used.

I read in another thread that the ends of the arms should have 16" of travel, and be.

4" off the ground in the lowest position
20" off the ground in the highest position

Does this sound about right?

Doug, you could do it like I did on my MF16. That's a 1450 3pt. The lower arms are attached to the axle, but
in order to maintain the geometry, I made up a standoff bracket.

Maybe a bit smal to read. Bigger files are in the manuals somewhere. In MF I think.

That's the set up I'm going to try to make it is a close match to the original.

Well, you've got the dimensions on that pretty grey tool box.
Notice how I had to mod the cylinder mount on the rockshaft.

Yes I did and that's the key to modify the rockshaft so the fender pan fits without cutting it up.

Compared to DH1's cylinder, slow and not very strong.

Speed: 8 mm (5/16")/sec ======= 1.75"/sec @ 2 gpm (Charge Pump)
Max Thrust: 1350 lb ======= 2200 lb @ 700 psi (Charge Pump)
Rated Load Thrust: 375 lb ======= 9420 lb @3000psi.

The reasoning for the screwy numbers for the 2 thrust ratings for the cylinder; 2200 lb is the thrust that can be generated by the pump and 9420 lb is what it can handle as an impact load going over a big bump at speed. The electric unit can develop 1350 lb, but it can only hold 375 lb..

Doug, on that setup I did, the bottom of the cylinder is 8 1/2" off the ground. The cylinder
is 10" pin center to center when retracted. That Princess cylinder isn't going to leave you
much ground clearance, unless you can figure out some fancy bracketry for the rod end
mount.

Possible solutions; lay the cylinder down under the seat a la 1450-1855 tractors, or, along the outside of the frame and behind the tire as I did with my 12H (if clearance allows). I used a 1.5 X 8 cylinder on the 12, with a longer bellcrank for the rockshaft.
