Introduction
Yanmar SA221 Sub-Compact Utility Tractor
The Yanmar SA221 is a sub-compact utility tractor produced between 2014 and 2022. Designed for versatility in landscaping, property maintenance, and light agricultural tasks, this machine combines a compact footprint with the durability of a dedicated utility tractor.
Engine and Performance
The tractor is powered by a liquid-cooled 1.0-liter, 3-cylinder Yanmar 3TNM74F diesel engine. It generates a net power output of 19.4 hp (14.5 kW) and a gross power of 21.5 hp (16.0 kW). The engine is tuned for consistent torque delivery, peaking at 39.4 lb-ft (53.4 Nm), and meets Tier 4 emission standards.
Transmission and Drivetrain
Equipped with a hydrostatic transmission, the SA221 offers infinite gear ratios for both forward and reverse, allowing for precise speed control without shifting gears. The drivetrain features a standard four-wheel drive system to ensure traction across varying terrain, supported by wet disc brakes for reliable stopping performance.
Hydraulics and PTO
The hydraulic system utilizes an open-center design with a total pump flow of 4.3 gpm (16.3 lpm) and a steering flow of 3.7 gpm (14.0 lpm), operating at a pressure of 1891 psi. The tractor features independent rear (540 rpm) and mid (2000 rpm) power take-off (PTO) shafts, providing the flexibility to operate both rear-mounted implements and mid-mount mowing decks.
Dimensions and Capacity
With a wheelbase of 57.9 inches and a total weight of 1537 lbs, the SA221 maintains a compact profile suitable for tight maneuvering. The rear three-point hitch is a limited category 1 type, capable of lifting up to 660 lbs at 24 inches behind the lift points.
Conclusion
The Yanmar SA221 is engineered for operators who require a reliable, maneuverable machine for property maintenance. Its combination of hydrostatic drive, independent PTOs, and 4WD capability makes it well-suited for diverse tasks ranging from mowing to light material handling.
