Engine and Performance
The tractor is powered by a Yanmar 3TNV80F, a 1.3-liter, 3-cylinder liquid-cooled diesel engine. It produces a gross power output of 23.9 hp (17.8 kW) and a net power of 21.7 hp (16.2 kW) at a rated speed of 3200 RPM.

For implement operation, the tractor features independent rear and mid PTOs, with the rear PTO operating at 540 RPM. The rear three-point hitch is a Category I (Limited) type, offering a lift capacity of 1209 lbs (548 kg) at 24 inches behind the lift points.

With a wheelbase of 63 inches and a total length of 105.8 inches, the tractor maintains a compact footprint. It has a base weight of 1830 lbs (830 kg) and a ground clearance of 9.9 inches. The unit comes standard with a two-post folding ROPS for operator safety, with a four-post canopy option available on specific configurations.
