Are there any out of the ordinary tools required to change out the shaft?

Any advice?

Thanks again. I'm a greenhorn on this one. Never needed more than 540 RPM until now.

This is a stupid question, but here goes anyway.

Are you sure your 1850 has the two speed PTO?
I don't think all of the tractors have the capability to go from 540 to 1000.

It is not as simple as the JD 4020s where you just change the shafts. On the Ollies you have to "shift" from 540 to 1000 like Don says.

No such thing as a stupid question...

I thought all 1850s came with a 2 speed PTO. I sure hope so. I just bought a 1,000 RPM mower!

No just a pair of plyers.Squwezze the snap ring and remove,then pull the shaft and bearing as one piece.If everything were perfect no oil would come out,but with an old tractor some will.Remember to shift while the shaft is out.

He did leave out one thing, a 3/8" bolt and a wrench to turn the lock screw on the shift rail underneath. There should be a bolt underneath w/ a jam nut on it, that holds the shifter in place. Loosen that, screw a 3/8" bolt into the end of the shifter, and push/pull depending on which speed you need. It is cast into the rear end, ussually covered in grease which way is what.

Also, you will probably have to lengthen the drawbar underneath, so don't put that 9/16" wrench away yet!!!

It takes me MAYBE 5 minutes to do the 1855, so yeah it is a really simple set-up.m Better than most, although IH definatley has it the easiest, NO change over, just put it on the other shaft!!

One more thing if the shaft has not been out lately it can be tight.I like to put on a pto extension that way i can grab it with both hands and if i need to tap it with a hammer to get started.

Good idea. I'll use that tip I bet. The shaft has not been out at least 4 years.
