Walker Manufacturing continues to build on its Model S platform with the introduction of the S18. The S18 features an 18-hp. engine and Walker’s patented Grass Handling System blower with Thru-Shaft PTO. The S18 is faster and more powerful, and with reduced weight, it is designed to be productive and efficient. Able to run 36- to 56-inch decks, the S18 is ideal for residential properties, gated yards, and demanding customers.
