My new L3400 arrived yesterday afternoon. WOW what a tractor!!! I've had an old Bolens g152 for many years and was impressed with this new machine. Twice the size and power. I only had time to ride around in the yard and woods when I brought it home. Only has half hour so far. Any ideas as to breaking in period etc...? I will mainly use it for mowing and maintaining my 6 acres and ride down the road to in- laws for plowing gardens and such. Will post more on it when I've added more hours. Gunman
