Introduction
Bolens QT-16 Garden Tractor
The Bolens QT-16 is a garden tractor produced between 1973 and 1978, designed for residential lawn care and light landscaping applications. It features a compact design, a hydrostatic transmission, and a horizontal-shaft engine configuration common to that era of garden equipment.
Engine and Performance
The tractor is powered by an air-cooled, horizontal-shaft, opposed-twin engine with a displacement of 659 cc (40.25 ci). It produces 16 horsepower (11.9 kW) at a rated speed of 3600 RPM. Maintenance requirements include a 2-quart (1.9 L) oil capacity with a recommended change interval of 50 operating hours. The fuel ignition system utilizes a Champion H8 spark plug with a gap of 0.025 inches (0.635 mm).
Transmission and Drivetrain
Equipped with a Sundstrand 15 hydrostatic transmission, the QT-16 provides infinite forward and reverse speed control. This shaft-driven system allows for smooth acceleration and deceleration, which is advantageous for maneuvering around obstacles. The transmission housing has an oil capacity of 10 quarts (9.5 L).
Power Take-Off and Hydraulics
The machine features an independent mid-mounted PTO as standard, with an optional independent rear PTO available. The attachment engagement is managed via an electric clutch system, providing the operator with convenient control over powered implements such as the 48-inch mower deck.
Dimensions and Chassis
The tractor is built on a 48.5-inch (123 cm) wheelbase with an overall length of 70.5 inches (179 cm) and a width of 30.25 inches (76 cm). With a shipping weight of 850 lbs (385 kg) and a ground clearance of 7.5 inches (19 cm), the unit is designed for stability on varied terrain. The operator station is open, though a soft-side cab was available as an optional accessory for weather protection.
Conclusion
The Bolens QT-16 is a durable, utility-focused garden tractor suited for landowners requiring a versatile machine for mowing and light implement work. Its hydrostatic transmission and independent PTO systems make it a functional choice for vintage equipment enthusiasts and hobbyist users.
