The Wheel Horse 612-Z is a zero-turn mower produced between 1990 and 1991, designed for residential lawn maintenance and property management. Manufactured by Wheel Horse, a division of Toro, this machine focuses on maneuverability and operational efficiency for grass cutting tasks.
Engine and Performance
The tractor is powered by an Onan E125V gasoline engine. This single-cylinder, air-cooled unit features a vertical shaft design with a displacement of 388 cc (23.7 ci) and generates 12 hp (8.9 kW).

Transmission and Drivetrain
The 612-Z utilizes an Eaton 780 hydrostatic transmission, which allows for infinite forward and reverse speed control without the need for manual gear shifting. Power is delivered to the rear wheels via a two-wheel drive system. Maneuverability is enhanced by integrated power steering, assisting the operator in navigating tight turns and obstacles.
Implement Operation and Dimensions
The mower is equipped with an independent mid-mounted PTO (Power Take-Off) controlled by an electric clutch, facilitating the use of a 38-inch or 42-inch mower deck. With a wheelbase of 42 inches (106 cm) and a total weight of 683 lbs (309 kg), the unit maintains a stable footprint. It features specialized lawn and turf tires, with 11x4.00-5 dimensions at the front and 18x9.50-8 at the rear, designed to minimize soil compaction.
