Mikey, a great tractor to own. If it is a 4wd, make sure you keep the front axle rear pivot greased and the axle topped with gear or hyd/trans. oil. Both pivots need greasing, but the rear also has an oring that can get dirt in it which can cause oil to leak from here. If there is no leak you're fine, but if it leaking you stand a good chance if loosing the reversing box gears or the front differential. Also, make sure the tierod hasn't been bent and rubbed under the reversing box.
Maintain the tractor and it will be a great purchase.
