I don't think it's the tires because it feel like a roughness in the drivetrain to me. I have felt the bumpy ride of driving the tractor when it sat in cold weather and the tires had flat spots but this isn't that. I like the idea of getting it up on jack stands and running it because maybe I'll see something. I just can't imagine what could be wrong with the
4wd system with only 100 hours on the tractor and probably on a a few of those hours were in
4wd. I try to plow in 2wd whenever possible and only 2
4wd as necessary.
I did have to top off the front axle fluid at the 50 hr. service because it was low but it should still be up there because there is no sign of a leak on my garage floor.
Between this and the
pto solenoid that appears to be broken I'm starting to lose my enthusiasm for this green toy.
