mower wont drive wants to but wont , i can hold one wheel and spin the other in either direction " in nuetral ofcource " i can also spin one wheel forward and the other spins opposite just like any other differential , so this to me means the rear end gears and chain are ok , am i correct on this asessment ? also while it is upright i noticed the LH fender bearing is destroyed so the axle flops around . could this cause the mower to not drive when engaged :thumbdown:? thank you
