Model R22
The perfect residential mower
R22 Model Overview
The R22 is the perfect machine for residential properties. With a belt-driven deck, operation is smooth and quiet without compromising on any of the Walker Mower's distinct advantages.
A variety of improvements have been made to the Model R for better operation, more reliability, and an overall increase in performance. The highlight of these improvements includes using the Kohler KT722 engine. This 22 HP engine has a higher displacement, increased horsepower, and greater torque and is an excellent complement to the earlier updated, larger displacement engine muffler that gives quieter operation.
This machine is a premium Walker Mower priced for residential owners.
