You could take the vari-drive out and turn it to run horazontal. All it needs is a spring loaded belt tensioner they have one on the unit. You would use it inplace of a jackshaft just two belts the same as a jackshaft useses. Don't need all the other stuff that is under the tractors. John Deer 112 had the best ones they were all machined out of heavy steel. They were also smaller ones used in industrial equipment. I will be trying to make a small one to use on a motor bike a little later this winter....just so you know...Curt
