     The Model MB is an exciting addition to the proven Walker Mower line. This simple, clean design uses the same principles as the original Walker Mower. These features include: tilt-up body, zero-turn manoeuvrability, a low centre of gravity and operator comfort in an even more compact configuration. The tractor design has been simplified and is even more economical for non-catching applications through the elimination of provisions for the built-in Grass Handling System (GHS), which is used on other Walker Mowers.

    Two independent Hydro-Gear transaxles are matched to Walker's unique control system using a forward speed control and two steering levers to make an agile, easy-to-operate tractor with ground speed up to 12.8km. The 18-hp Briggs Vanguard engine, in conjunction with a manually-engaged mechanical clutch, provides an efficient delivery of power to the mowing deck. Commercial and residential operators alike will find this machine a strong and efficient performer in the Walker design tradition. 


    Walker’s engineering took a close look at how to provide proven Walker ideas in a reasonable price category while not compromising Walker quality--the result was the simple, beautiful and basic design of the Model MB. Proven components teamed with Walker detail and design discipline has set the bar at a new height in affordable zero-turn mower technology.
