The Walker MR21-42 (Model R21) is a dedicated residential zero-turn mower designed to bring the premium Walker mowing experience to home owners. Its belt-driven blades run smoothly and quietly while preserving the Walker advantages of out-front deck visibility, tight manoeuvrability and an excellent finish.

Built around a 21 HP Kohler KT620 V-twin engine, the Model R delivers reliable power for regular residential mowing, including complex lawns with garden beds, trees and uneven ground. The integrated 42 inch DS42R side discharge deck is carried on independent articulating deck arms, allowing it to flex up and down to follow ground contours. This helps minimise scalping and uncut patches, leaving a cleaner, more even result.

A torsion-flex carrier frame lets the deck move side to side as well, so the mower can track smoothly across undulating areas. Hydro-Gear EZT integrated transmissions with Walker’s precision steering levers provide controlled, responsive zero-turn handling. Standard features such as forward speed control, tilt-up deck, tilt-open seat panel and good access to service points make ownership and maintenance straightforward for residential users.

For homeowners who want fast, easy, high-quality mowing and a compact machine that is comfortable to operate and simple to look after, the Walker MR21-42 is a strong long-term choice.
