PTO on MH 44

I've used my 1953 MH 44 mostly for puttering around and some light pulling (when I get my MH 50 stuck in the mud and the like). I was looking to get a haybine to get some more work out of her, and thought I'd better check out the PTO. Imagine my surprise to find that it is a ground drive PTO, not a live takeoff. None of my literature describes it as such.

Do I have an unusual critter? Is there any way to change this out to live PTO?

Thanks for any help.
Steve

This is an engine driven PTO not a ground driven PTO. It's speed is in direction relation to the engine speed and not the ground speed. I realize it isn't an independent or continuis. Some of the later MF tractors have two positions on the PTO engagement lever so you can run in a ground driven or engine driven mode.

Thanks to everybody. Regarding the terminology, I understand that a ground-drive PTO turns at a speed proportional to your ground speed, not engine speed - so that when the tractor is still, the PTO doesn't turn. It would seem to me that this would be tough to mow with, since if you slow down when things get thick, the mower speed will slow down and it will not cut as well.

My MH 50 has a 2-way PTO - ground drive and engine drive. Haven't seen any time to use the ground drive position - the manual says it is used for hay rakes, but I've not seen a rake that would run off the PTO (and don't konw why that would be any better than the wheel driven or passive ones).

I do have a hand clutch, which I've not fiddled with - I'll see what that does this weekend.

Again, thanks to everybody.

I've got a 44 special,it does not have live PTO.I bought it sight unseen and was told it had a hand clutch,it didn't.. an over running pto adapter would help alot.I plan to try to run a mower conditioner this summer with mine if I can find a hydraulic pump for it.I've heard the term ground drive PTO used before,what is the correct term to use if thats not right? In my opinion without live PTo and live hydraulics it's just a relic that belongs in a museaum,because it just ain't very useful,but still I plan to try to use it as much as I can this summer.

Steve,
Not unusual, by 1950, a secondary over ride hand
clutch was an option through 1957, located on the right side, between the brake pedals and fender. Double disc brakes were part of the package, and
they were great. After a few decades, the live
clutch would need service/adjustment, but MF ignored MH. A slipping clutch under load or
chatter, drag, meant buy a new tractor to MF
dealers. Aged brake seals added #90 gear oil to
the disc brakes, this could all be corrected. But
to convert your Bendix shoe brake 44 to disc
brakes with a good live clutch, takes a good
guy about a full day, with knowledge of the springs and disc condition. 44 Specials seem to
be the most popular model to have live clutch,
though 33's,44's and 333/444's are still running
this option. The Specials and Triples interchange.
Some early updates, pedals conflict on earlier
33/44's. A challenge for a novice, major advice
required to assemble/adjust properly.

Steve I don,t agree with your definition of ground drive P T O You can run it without tractor moving and if you have a pulley you can saw wood or run a threshing machine. The 44 special and 444 have live pto Doon,t know about 44,s butt think not. You can run haybine and stop moving by kicking tractor out of gear. not easy but youcould get by in a pinch it,s the way we used to do it before live pto hope this doesn,t confuse you good luck bob
