I have one myself, The FF24 is a work horse, you did really good on that buy. I took mine down to nothing and Soda blasted it and painted everything. I just got the motor back in the tractor That motor is one tuff-built motor, you can get parts with no problem, If you are looking to sell that P.T.O I would buy it, I have that shaft there that is broken, I have the rear backhoe and the front blade for mine. This tractor never fails me on my orange farm here in Northwest Fla, Buy Spring harvest mine will be going nonstop.
Man that is a great deal for $500. All the ones I have i paid $500 as well. This weekend I got two. A working 24 with a back grader blade $500. + a blown engine ff/18 with spare engine, front and rear PTO and the super rare, 3 Point finishing mower. I did have to pay a bit extra for that one. $600 LOl
