The Yanmar SA425 combines impressive power, stability and versatility in a compact, easy-to-operate tractor. Powered by a reliable 23.9 HP Yanmar 3-cylinder diesel engine, the SA425 is an excellent choice for homeowners, property owners and small farms looking for one machine that can handle mowing, loader work, landscaping, snow removal and general property maintenance.

A dual-range hydrostatic transmission makes operation simple and intuitive, while selectable 4WD and a standard differential lock provide added traction when working on hills, loose material, mud or snow. The SA425 also features true position control for the 3-point hitch, allowing you to return an implement to a consistent working height when grading, mowing or performing other 3-point work.

Designed for more demanding terrain, the SA425 features larger, more aggressive tires, increased ground clearance and heavy-duty cast iron rear axle housings for improved stability and traction. Unlike tractors assembled from drivetrain components sourced from multiple manufacturers, Yanmar designs and manufactures its major drivetrain components—including the engine, transmission and axles—to work together as a complete system.
