I've had more troubles than I expected with this tractor(transmission, motor rebuild). It's in the shop now for the second time for front axle troubles. I hear this grinding noise and then lose four wheel drive and the front wheels lock up even with the 4 lever out. I noticed they use the exact same axle on the L2900. seems they should have beefed this one up. I'd like to upgrade to a L5040GST i keep thinking there's nothing left to fix on this tractor, and then there is.
