The Model S is the quintessential Walker Mower. Inspired by the original 1977 prototype, the Model S is simple and easy to operate, and very efficient at mowing residential properties. With Walker’s Grass Handling System™, a patented Thru-Shaft™ PTO blower design, and reduced weight and cost, the Model S is the perfect entry-level mower for experiencing Walker’s signature beautiful cut and zero-turn productivity.
The Model S is perfect for residential lawns. The Model S features Walker’s Grass Handling System™ (GHS) with a patented 12.75 inch Thru-Shaft™ PTO GHS blower and a 7.0 bushel grass catcher. The compact design, coupled with Walker’s precision steering levers and Forward Speed Control, makes getting in and out of tight landscape features and obstacles possible, minimizing hand-held trimming and walk-behind mower time.
The lightweight, balanced design improves steering agility, shortening overall job time. Integrated Hydro-Gear ZT3100 transmissions are durable and provide precise maneuverability and industry-wide service and support. The Model S is engineered for affordability and efficiency. With commercial-grade components and multiple configurable add-ons, the Model S is a serious tool for commercial operators maintaining compact, complex properties.
