Hi Jeff,
I think it is a 21 inch cut engine directly on the blades and belt drive to the drive system. So much better that the rubbish Honda boxes. I think it is similar to the Snapper drive very simple and can be adjusted whilst moving to whatever speed you want. My father bought one in the early nineties and my grandson is still using it. It has a blade bar and it looks as if it has done quite a bit of work with the Suzuki on it
