SA221

21.5 Engine Horsepower* Diesel Tractor

SA221

The SA221 is a fully outfitted, multipurpose compact tractor, powered by fuel-efficient three-cylinder, liquid-cooled Yanmar diesel engine. We designed this tractor to generate more usable horsepower and deliver a smoother, more comfortable ride. You’ll quickly appreciate the redesigned open platform, with its convenient and easy-to-use controls that simplify operation for users of all experience levels.

Innovative design and technology

Compact tractors, fueled by efficient but powerful diesel engines, provide the versatility to handle any job around your property. Here’s a quick look at SA221 tractor features to help you get the most work done:

  • Hydrostatic transmission with dual pedals for simplified operation
  • Power steering for less operator fatigue
  • Power takeoff (PTO) and three-point hitch for attachments
  • 21.5 horsepower

Built together to work together

The SA221 packs the power you’d expect from a much larger tractor. That means the SA221 can do serious work with a front-end loader, a hydraulic backhoe and three-point hitch attachments for mowing, tilling, planting, digging, plowing and so much more.

Yanmar designs and builds the major components – engine, front axle, transmission and final drive – to work together. We also smoothly integrate these features and optional attachments so you can get more work done quickly:

  • Yanmar-designed front-end loader, with class-leading lift capacity of 825 pounds and quick-attach for buckets, forks and other attachments
  • 60-inch, mid-mount, drive-over mower
  • Dual hydraulic pumps
  • Smooth hydraulic power steering
  • One-touch on/off, electro-hydraulic, independent rear PTO
