Overview
The S18 continues to build on the Model S platform with an 18 HP engine and Walker’s patented Grass Handling System with Thru-Shaft PTO. It is faster and more powerful, and with reduced weight, the S18 is designed to be productive and efficient. Able to run 36 to 56 inch decks, the S18 is the perfect choice for residential properties, gated yards, and demanding customers.

R22x Model Overview
The Model R22x offers commercial landscapers an on-ramp to the full Walker line up. It delivers the same smooth, quiet, and reliable performance operators expect, with great versatility and ease of use.

This is achieved through a combination of upgrades: commercial-grade transaxles enable use by contractors for high-demand properties; a well-cushioned comfort seat enhances operator comfort; 20-inch drive tires provide superior traction on diverse terrains, coupled with spread axle tail wheels add exceptional stability and a smooth ride; and integrated headlights ensure safe operation during low-light conditions.
