Introduction
Bolens G154 Sub-Compact Utility Tractor
The Bolens G154 is a sub-compact utility tractor produced by Iseki between 1978 and 1991. Part of the G152/G172 series, this model was designed for versatile agricultural and property maintenance tasks, offering a balance of compact dimensions and mechanical capability.
Engine and Performance
The tractor is powered by a liquid-cooled engine with a displacement of 0.7 liters (40.8 cubic inches). It delivers 15 horsepower (11.2 kW). The engine utilizes a dry element air cleaner and is equipped with a 12-volt electric starter and glow plugs for reliable cold-weather starting. Routine maintenance requires an oil change every 100 hours, with a total engine oil capacity of 2.6 liters.
Transmission and Drivetrain
The G154 features an unsynchronized gear transmission providing 6 forward speeds and 2 reverse speeds. Operation is facilitated by a dry disc clutch. The drivetrain includes a four-wheel drive system and a mechanical rear differential lock, which assists in maintaining traction on uneven or loose surfaces. Braking is managed by mechanical internal expanding brakes.
Power Take-Off and Hydraulics
The rear power take-off (PTO) is transmission-driven and offers three distinct operating speeds: 472, 752, and 1177 RPM, all achieved at an engine speed of 2700 RPM. This versatility allows the operator to match the PTO speed to the specific requirements of various implements.
Dimensions and Chassis
With a wheelbase of 128 cm (50.4 inches) and a ground clearance of 25 cm (10 inches), the G154 is configured for maneuverability in tight spaces. The tractor has a base weight of 509 kg (1124 lbs). It features an open operator station with manual steering, and it is standard-fitted with 5.00-12 front tires and 8-16 rear agricultural tires.
Conclusion
The Bolens G154 is a robust, sub-compact utility tractor well-suited for small-scale farming, landscaping, and private property maintenance. Its combination of four-wheel drive, multiple PTO speeds, and compact physical footprint makes it a capable machine for users requiring a reliable, entry-level utility tractor.
