The RK55H is a compact utility tractor introduced in 2017. Manufactured by TYM and distributed by RK Tractors, this machine is engineered for versatile agricultural and property maintenance applications.
Engine and Performance
The tractor is powered by a Yanmar 4TNV86T-CR engine, a 2.1-liter, 4-cylinder turbocharged diesel unit featuring common rail direct injection. It produces a gross power output of 55.1 hp (41.1 kW) at a rated speed of 2800 RPM. The engine is liquid-cooled, ensuring thermal stability during prolonged operation.
Transmission and Drivetrain
The RK55H utilizes a hydrostatic transmission providing infinite forward and reverse speeds across three distinct ranges. This system is paired with a four-wheel-drive configuration, enabling effective power transfer to the ground. Maneuverability is facilitated by power steering, while stopping power is provided by wet disc brakes.
Hydraulics and Hitch
The hydraulic system provides a total flow of 14.5 gpm (54.9 lpm), with 9.5 gpm allocated to pump flow and 5 gpm dedicated to steering. It features two valves for implement control. The rear Category I hitch offers position and draft control, with a lift capacity of 2945 lbs (1335 kg) at 24 inches behind the lift point, and a maximum capacity of 3314 lbs (1503 kg) at the ends.
Power Take-Off
The tractor is equipped with an independent rear PTO operating at 540 RPM. The engagement is managed via an electro-hydraulic clutch. An optional mid-PTO is available to increase the machine's utility for mid-mount implements.
