Am trying to replace the upper drive belt on the MTD lawntractor. Does anyone have any opinions or comments on the easiest way to do this. Also replacing the pivot bar on it, there again any comments on either of these subjects????
That belt is relatively easy to replace. You need to disconnect the battery and remove it and lift out any battery holder.
With the battery and holder out of the way, you can easily access the belt and remove it from the pulley's.
On some models the clearance between the frame and transmission input pulley is too tight for the belt to slip off. On these, remove the (4) mounting bolts attaching the transmission to the frame and shift the frame a little to remove the belt.
