small PTO

Early Ford's and Ferguson's had a small PTO shaft. Most people used the adaptor to use a regular size PTO implement.

Some replaced the shaft.
Was there every any implements that had a small PTO?

I have not seen any implements like that

yes the early fords and ferguson's had matching pto powered impliments

Early Farmall H had a small pto, we had a 27 mower and an old IHC manure spreader that had the small pto. Did the M ever have a small pto or just the H? Never saw one. Farmall B was small....James

The old bolt on belt pulleys were 1-1/8".
I suppose there could have been other things from older days but I've never seen any myself...

The mower I have had one 1 1/8 " I changed to 1 3/8 so I could use on my tractor. Mower is a 14-2 Dearborn I think that was the first 3 pt hitch mower they made, was made for the 9-N. I use on a 1715 Ford/New Holland.

Yes all the early implements were for 1 1/8 " and J D had the small pto on the A & B tractors. That small pto on the fords was not intended for any implements to be attached to it tho when it was designed and they had a extension that converted it to standard 1 3/8" and also when used with the V drawbar converted things to the standard that is still used today. It was only to be used with the PTO extension or belt pully. David Bradley made the first rear mount mower for that tractor and it did not use the 3 point lift arms but a rigid mounting modified from the mountings for a F20 Farmall and used a pully mounted on the pto, not a shaft (pully may have been same one used on the F20). Later Ferguson sold that David Bradley built and designed under the Ferguson name, then came the Dearborn and Ferguson mowers that mounted on the 3 point and was built by Detroit Harvester that modified a Detroit Harveter built Case mower built fot the VA series and converted it for the 3 point hitch and shaft drive and with the mower raising and lowering with the hitch they could not use the belt drive like previous mowers did that were rigid mount. The PTO on the orignal Fords was never intended to be used with any mounted implements, only pull type implements that the PTO extension that Ford sold extende the PTO shaft about 12" (would have to go out and measure mine to be exact) and that with the V extension-brace that set the hitch pin about 5" behind the cross drawbar gave the standard 14" between thr rear end of the PTO shaft and the hitch pin hole that is still the standard for all 540 RPM implements.

The old Model 12 BushHog had small pto to fit 8n.

The early M did have a different style of PTO, but I believe the shaft was still the 1 3/8"

I just purchased an Over Running Clutch for my Fergie, that also adapts from 1-1/8" to 1-38" diameter. That way, I can run a bush hog and not worry about the implement propelling the tractor forward when I step on the clutch. Same goes for any of the high inertia pto machinery, like saws, snow blowers etc.

The only reason I kept the small pto was for the belt pulley which was used to run the buzz saw.

Be careful.
