After all these years (1993) Time for a new engine. The 20 HP Kohler was rebuilt once and with the prices of the machine shops and parts to go 0.030 over, it looks like the better way to go is another engine. Harbor Freight 22Hp Predator looks about right. Aligning the new engine and hooking up the electric and drive belts for the mower is easy. My question is the drive for the pumps comes off the front of the flywheel. Has anyone done this swap? And if so what do I need to adapt the Predator flywheel to the shaft that drives the pumps? As Always, THANKS for all the help in advance!
