Introduction
Kubota GT-21 Compact Utility Tractor
The Kubota GT-21 is a compact utility tractor manufactured by Kubota between 2001 and 2002. Designed for versatility in agricultural and utility operations, this model provides a balance of power and maneuverability, featuring four-wheel drive and a liquid-cooled diesel engine.
Engine and Performance
The tractor is powered by the Kubota D1403 engine, a 3-cylinder diesel unit with a displacement of 1.4 liters (85 ci). This liquid-cooled engine delivers 20.7 hp (15.4 kW) at a rated speed of 2600 RPM. It utilizes an electric starter with a 12-volt system to ensure reliable operation.
Transmission and Drivetrain
Users can choose between two transmission configurations: a 12-speed manual gearbox (12 forward and 4 reverse gears) or a 3-range hydrostatic transmission providing infinite forward and reverse speeds. The tractor is equipped with a four-wheel-drive system to enhance traction across various soil conditions.
Hydraulics and PTO
The GT-21 is equipped with a Category 1 rear hitch for implement attachment. The rear power take-off (PTO) offers three selectable speeds—540, 750, and 1000 RPM—accommodating a wide array of agricultural implements and power-driven tools.
Dimensions and Operator Safety
The tractor has a wheelbase of 57.1 inches (145 cm) and a ground clearance of 12.6 inches (32 cm), contributing to its agility. Depending on the transmission, the weight ranges from 1940 lbs (879 kg) for the gear model to 2028 lbs (919 kg) for the hydrostatic version. For operator safety, it is fitted with a two-post folding Roll-Over Protective Structure (ROPS).
Conclusion
The Kubota GT-21 is a durable, compact machine suited for small-to-medium scale agricultural tasks, orchard maintenance, and general utility work. Its combination of multiple PTO speeds and flexible transmission options makes it a practical choice for operators requiring a reliable, maneuverable tractor.
