Frequent leaks have been addressed by the dealer. We replaced the gas tank as it had collapsed, and replaced the Titan front tires because of frequent leaks. There have been no problems with the Firestones.
It is a good spray tractor, with lots of amps for running the controls. It's too small for anything but limited big round baler use. Will not start when below -25 F, plugged in or not. Brakes have to be pumped two or three times to function well, but will catch on the first pump...a little. It has a good cab, and the air is as dependable as is the heat. The radio was replaced when it failed.
Awkward loader controls have gotten worse with time. I have to go over the tractor once per week with a wrench to tighten all the loose fittings.
Would not consider buying this tractor again.
