Simplicity uses a belt inside out an hits the other side of pulley. ---that does work, or has been working on mine, a model 7016RT. ---I have a couple vertical b&s 3hp that have cam reverse pulley on Hahn front tine tillers.-- these don't run anymore. My parents bought it new in the early 60's for $ 149.95 from Miller Hatchery and Hardware store, paid for it with their egg sales money, and I did garden tilling for town people with it to repay the folks back plus whatever I could get to help the family.
Hauled the tiller around in an old trailer behind the Oliver 70 tractor. ( my wheels at the time since I wasn't old enough to drive legally! )

That was some interesting times back then!
On the jackshaft idea, I need to come up with something for a David-Bradley walk-behind garden tractor to slow the speed down.
