The original subject was "pto problems on a Case 2290".

we just sheered the second key in my friends 2290. we have no idea why it is breaking. his 2290 came with the #13 woodruf key in the lower idler gear which they switched to a #15 later in the production run. we are going to try to get it machined to the bigger key and try again. I would love to hear from anyone with the real fix to this problem. By the way we were using a newholland discbine both times in a smooth field in short hay with little load

It could be that the operator is pulling the pto knob up too quickly when starting the pto.

Idle the engine, ease the knob up slowly and watch the pto shaft slowly start to turn and gently pull it to the top position.

These tractors will snap the pto in too quickly if the engine is sped up or it you do it too fast.

We have run these good ole tractors forever but if the operator is in a hurry or careless they will break the key.

We never break a key but my Dad had an employee years ago that would break one about every day no matter what you told him or showed him. He did not last long!

By the way, my 2290 hit the dyno at 159 hp.

Thanks for the advice, but there are no bad operators involved with this tractor. We wish the answer was that easy. We looked into getting the woodruff key grove on the shaft and gear machined to the next size bigger and found out they are made of a very hard steel that would be very expensive to get done. New gear and shaft is around $660. New hardened keys $6 for 25 of them.
