Lift capacity of the MF-135 3pt?

[flusher]

Anyone out there know the answer?

When new the lift capacity was rated at 2290 lbs. This was with front weights fitted of course !! I have a nieghbor who lifts 1500 lb bales with his no problem. Hope this helps, JJ.

The 2290 lbs figure is quoted in several manuals, so that must be about right. The same hydraulic system/3-point hitch components are used on the 150, and essentially the same thing on the 165 with higher weight capacity on both of those models. There is an internal adjustment that can increase lift capacity somewhat. It's done with a simple adjustment to the "draft bump-stop screw". (clearance between head of screw and contact point on lift cover) I've worked on a couple "100 series" Masseys where the position control portion of the lift wouldn't quite raise what it was supposed to. Remove lift cover, flip it over, set clearance slightly closer than O.E.M. specs, and they'll perform like new. Takes about an hour with access to an engine hoist. (Or a couple strong backs. Lift cover is heavy and awkward)

I lifted a 4 x 6 round bale with my 2135 (industrial version) and it knocked like crazy. It picked it up the bale without any problems and the knock went away when I put it down. I asked about the knocking on another forum and they said it doesn't hurt anything, but it sure sounded bad.

Thanks for the input.

The only info I could find on the Web is a Swedish (?) website

MF traktoreiden teknisiä tietoja

The lift capacity there is given as 1300kg (2860lb). Wanted other input to verify this number, which looks to be too large.

That "knock" is the relief valve functioning PROPERLY. When you lift a heavy load and it DOESN'T knock, start worrying. My 150 has done that since new when the lift is raised all the way, load or no load. So does every 100 series Massey ever built if the relief is working.

European 135 (100series) tractors were still essentially the same as those sold in U.S. market, but were not EXACTLY the same. I'm digging through a pile of Massey sales literature as we speak, looking for specs on U.S. built/sold units.

GOT IT! My "GURU" tells me 2850 lbs on all models of 135's ,U.S. as well as European models.

I also just checked my MF 135 UK manual. That gives the lift capacity as 2850 lbs. Is there a difference in the lifts ?

So, 2850 lb is the agreed number?

Any idea whether this is a conservative number with built-in margin to handle overloading the 3pt by the user?

Or should this number be derated by say 10-15% to be sure nothing breaks in the 3pt system?

I assume from what's been said before in this thread that the relief valve in the 135 3pt hydro system is the built-in protection against cockpit error.
