Match this spline please

welding anything on the end will have to be small enough to slide a new bearing over. Sods law it will go once you weld to the end of the shaft.

That would be my opinion on the 250 but that doesn't help you much.

Was a farmer had a combine with no reverse unblocking on it, he put a engine ring gear on it then used the starter motor from the same engine when he wanted to unblock it.

Its a good baler, does all i need to do.
Its the unblocking lever thats a piece of sh!t
I am going to weld a 540 spline on and use a small hydraulic motor or connect it to a tractor pto to unblock it.
Putting in a drop floor is possible too

As long as its under 50mm

The nut is rounded
I think i will cut the nut off and weld on a 540 spline as the big splines seem far from common
Do you have an unblocking lever for jd?

Just get a bit of threaded bar the same thread as the nut and screw in then attach a new nut thats not rounded and lock both nuts together. You should then be able to get a long socket over both nuts and use a standard bar.

Its too big, 50mm across

20spline is a bigger Pot shaft than normal pto shaft

As mentioned; just weld on the biggest 3/4 drive or even inch drive socket you can find under 50mm od and then use a breaker bar or even ratchet, then it will always be in the best place for doing a ‘full pull’. Spline route will be awkward, heavy and expensive imo.

These are sometimes handy for making farmer fix machinery improvements..
