Howard Parker · Oct 31, 2015

well good news fixed the hydraulics on the R it was the pin came out half way on PTO clutch fork and was only engaging it sometimes plow lifts great now but I have another problem the hand clutch for the transmission snaps in and stays in good while driving it but when I snap it out to stop I really have to pull back hard then it will let loose and disingage what would cause that to happen? if I don't snap it in all the way it disingages ok thanks for any advise Howard

Check the adjusting bolts for the clutch for ware as they do get groves cut in where they slide through the other parts and if it gets to the point there is a sharp grove in them you cannot under any circunstances get the clutch out to stop and may wreck before you can shut down tractor. That getting hard is just a indicater of worn bolts. Same on any and all 2 cylinder Deeres with pully in clutch and common problem. It can be a deadly problem if not repaired.

Those clutches were often a problem. Brother was scooping snow with our Lemon G; he reversed and when he pulled the clutch it wouldn't release. Fortunately the drawbar hit a power pole dead center that caused the clutch to release. The drawbar made a hole in that pole about 5 inches deep; that pole is still in the farmyard. If the tractor had hit the pole off center, it probably would have pinned him in the seat and crushed him to death.

We learned early on to never stand behind that tractor to hook up an implement; the risk of being crushed if that clutch didn't release was too great. We tried everything to solve that problem but it never was trust worthy.

I will second Leroy in that the pins and internal linkage on the hand clutches need to be checked for wear when you have a clutch "stick" engaged. It kind of scares me to see these old hand clutch JD in parades. As I have had several over the years "stick" engaged when the pull pins and linkages gets worn.

I saw a fellow wipe out his pickup loading a JD "A" with a bumper trailer. His stuck on while loading the tractor. He got it killed as the front end hit the back of his cab and the rear tires fell off the front of the trailer. There he set with the tractor down in the rear between the truck and the front of the trailer. His front wheels had caved in the back window/cab of his short bed truck. The scary thing is he had followed the local girl scout troop through the parade. What would have happened if it had stuck during the parade??????

Lot of different possibilities on the clutch, as have been mentioned. Just to point out another....there are many people out there that were not raised on these old hand clutches. One thing that seems like has not been passed on is....always adjust the clutch with it engaged. If it has been incorrectly adjusted it can cause a problem.

Another thing....most people adjust their JD 2-Cylinder Clutch entirely TOO Tight..

These tractors had way more "Clutch" than necessary and need NOT be adjusted "Tight"..

The clutch handle should snap in with hardly more than 5# of pressure and is ok with less, as long as it barely "Snaps"..

I think it always requires more force to Dis-engage them, so as they are set tighter, it takes more pressure to pull the handle back..

Agreed, he needs to tear the clutch completely down and inspect all parts, clutch discs and grease/Lube it..

Once completely checked, it should be good for many years without service..(It may have been 30 years since it was last serviced)...

It is not hard to do and actually is quite an interesting mechanism..!!

I'm sounding repetitious, but here goes. Idle her down when you are doing close work. High idle on the old two lungers isn't much faster than low idle on some newer engines so folks who aren't used to running a two banger tend to keep that throttle open too far. When we are accustomed to a tractor that falls on it's face at very low RPM's we tend to want to keep it revved up. The clutch pulley does tend to not want to stop when the engine is running fast due to centrifugal force keeping it engaged.

Brother gave it to my nephew who had an interest in 2-cylinder JD's. Since that time he has become disillusioned with JD so it is parked somewhere doing nothing. It was a 1948 G with narrow front. The cushion seat was the best thing about the whole tractor.
