Engine and Performance
The tractor is powered by a Shibaura N843 3-cylinder liquid-cooled diesel engine. With a displacement of 1.5 liters and a rated speed of 2600 RPM, the unit delivers a gross power output of 31 horsepower (23.1 kW). This powerplant is designed for consistent operation in various load conditions.

This capacity supports efficient implement operation, with 7.2 gpm allocated to the main pump and 5.1 gpm to steering. The tractor is equipped with a Category I rear hitch featuring position control, offering a lift capacity of 1,635 lbs (741 kg).
Power Take-Off (PTO)
Versatility is supported by a live rear PTO operating at 540 RPM. Additionally, an optional mid-mounted PTO, running at 2000 RPM, is available to drive implements such as mid-mount mowers, expanding the tractor's utility in maintenance and ground care tasks.
