Walker Mowers C23iSwing-Away Jackshaft

A unique swing away jackshaft design gives unobstructed access to the Grass Handling System blower and other drivetrain components for easy maintenance.

Walker Mowers C23iReliable Power

The 23 HP Command Pro ECH730 v-twin engine is a proven design with responsive power and adaptive Electronic Fuel Injection (EFI). Built around cast iron cylinder liners, a balanced rotating assembly, and high-quality components, the ECH730 is smooth, durable, and dependable. Coupled with industry leading EFI, the engine is efficient, consumes less fuel, lowers emissions, and is easy to start and operate. The 747cc displacement provides consistent power, even under heavy loads.

Walker Mowers C23i​​​​​​​Custom Drive System​​​​​​​

The C23i is equipped with dual, independent Hydro-Gear® ZT3100 integrated transaxles, providing rugged durability and an 8 MPH ground speed. Its agile, responsive design enhances maneuverability and efficiency, making it ideal for compact mowing areas.

Updated High-Output Blower​​​​​​​

Using an improved blower wheel design and a blower housing with an expanded scroll and larger diameter inlet, the internal blower has an increased material flow of 25% over the previous design—this helps make collecting grass at 8 MPH a reality. Additionally, the low-profile fixed chute optimizes the travel path of cut debris for improved performance.
