The very first Hustler 880 came with a single cylinder K-309 2 stroke Kohler. They also had an Apex gearbox with a jackshaft/clutchpack configuration for the drivetrain. Then they switched to a CCW 340cc two stroke, two cylinder and a T-20 transmission. I believe these were the only 2 engines available in the 880 fiberglass body Hustlers. Then they went to the the HDPE plastic bodies and 2 cylinder 2 stroke Kohler engines.
