International 3500a Pto?

dodgeram945 · Jan 5, 2012

I have an International 3500a with hydro drive and 3 pt hitch. I was wondering if it would be possible to put in the 2 speed ptos. The tractor has covers over where the ptos should come outin the back. I'm curious if anybody has a 3500a with the 2 speed ptos or if there is an agriculture version of this tractor out there that you could put the parts into this tractor. I would like to get the ptos working so I have a multi purpose tractor because I have too much money into this one with rebuilt engine and new tires. If anybody has info it would be greatly appreciated.

The transmission/differential gears and housing is the same as a International 574 farm tractor. To install a PTO in a 3500A, you would need to find a 574 Hydro and switch over all the parts which would be a big job since it uses a live shaft from the flywheel through the hydro transmission, back through the transaxle to a hydraulically operated PTO clutch. You will need the linkage to ooperate the clutch along with the parts at the rear of the tractor The PTO will be a single speed 540RPM.
