Re: Best Dual Speed Shifters?

This year we modified a Super Shifter to make a PTO. WHen we were done, it was nothing like the Super Shifter. We changed a lot of the ratios, worked in an extra CIM, changed the final stage ratio, and added a brake. Basically it was an easy package from which to get a lot of gears. Our final PTO product was absolutely nothing like the original Super Shifter, going through three iterations in CAD and two in real production. Also, we made some shafts coaxial using idler gears and bearings.
