Increase the diameter of the motor pulley to get more speed in the >transaxle so that LL speed falls between the old LL and L. I have done this with my IC tractor. Like split the gear. The only thing to over come with the GE's is the heat build up. You can have 1000cca batterys (tried this. Need 00 wire. ) 6 of these WILL heat things up. A LOT!! My $.05 worth. Matthew P. Magda Jr.
