The MT23, the company's most popular model at the time of publication, serves as Walker's base-model lawn mowing tractor. This tractor features a 23-horsepower Kohler OHV V-Twin engine, clam-shell chassis and ground speeds up to 5 miles per hour. The MT26 adds an electronic fuel injection system and bumps the horsepower rating up to 26.
Walker's model MTL tractor retains the electronic fuel injection system of the MT26, but adds liquid cooling to the mix. The MTL's Kohler Aegis V-Twin engine outputs 31 horsepower. This mower features an electric radiator fan with reversible self-cleaning action and ground speeds up to 7 miles per hour.
The Walker MBK simplifies the basic design of the MT. A streamlined drivetrain and an 18-horsepower Kohler Command engine power this mower, which features independent HydroGear transaxles. The MBV model retains these specifications, but features a Briggs & Stratton engine, remote air intake and a keyed drive shaft. Like the MBK, the MBV features a 2.8-gallon fuel tank, in contrast to the 4.7-gallon tanks of the MT and MTL models.
MBS model tractors cater to high-demand, commercial mowing jobs. The standard Walker MBS features a 26-horsepower, air-cooled Kohler Command engine with electronic fuel injection. It also sports a Cummins Filtration OptiAir remote air filter and dual 4.7-gallon fuel tanks. Walker also offers a 27-horsepower MBS mower without electronic fuel injection.
Walker's compact and maneuverable model MC employs a 20-horsepower Kohler V-Twin engine and features a tilt-up body with exposed drivetrain. Model MD, a diesel mower with a water-cooled 20.9-horsepower Kubota tractor engine, retains the company's characteristic clam-shell design but incorporates a self-cleaning electric radiator fan and splined drive shaft with a quick-disconnect coupler. Walker model MW serves as the company's only walk-behind mower, featuring a 15-horsepower Kawasaki OHV V-Twin engine with electric start, dual independent Hyrdrogear integrated transaxles, variable forward speeds and a tilt-up deck.
