The Bolens HT-20D is a garden tractor produced between 1980 and 1981 in Port Washington, Wisconsin, USA. Designed for landscape maintenance and residential property management, this model is recognized for its robust construction and hydrostatic transmission system.
Engine and Performance
The tractor is powered by a Wisconsin WD2-860 diesel engine, a two-cylinder, air-cooled unit with a displacement of 863 cc (52.7 ci). This engine, which is a rebranded Ducati 2IS22, delivers 19.9 hp (14.8 kW) at a rated speed of 3000 RPM. The engine features a bore and stroke of 84 mm by 78 mm and an oil capacity of 2.6 liters.
Transmission and Drivetrain
The HT-20D utilizes an Eaton 11 shaft-driven hydrostatic transmission. This system provides infinite forward and reverse speed control across two operational ranges, allowing for precise maneuverability. The machine is configured as a two-wheel-drive unit and is equipped with manual steering and disc brakes.
Power Take-Off and Hydraulics
For implement operation, the tractor is equipped with an independent mid-mounted Power Take-Off (PTO) system. The engagement of the PTO is managed via a manual idler clutch mechanism, providing the operator with direct control over attached equipment such as the 54-inch mower deck.
Dimensions and Electrical
The tractor features a wheelbase of 132 cm (52 inches) and weighs approximately 503 kg (1110 lbs). The electrical system operates on 12 volts, supported by an alternator with a 9-amp charging capacity. It is fitted with lawn and turf tires, measuring 18x8.50-8 on the front and 26x12-12 on the rear.
Conclusion
