I have my Father's Self Propelled Model # 21351PD. The transmission has been leaking for years out the axle shaft onto the drive pulley. I have researched around a few places and have found replacement transmissions (original part # 7059070 changed to 7053943yp) for $ 195.00. Is the best I can do. I have the original receipt of $449.95 this mower has more than paid for itself decades ago, but iam always looking for the best price and long life from my equipment.
