Introduction

Hefty G Tool Carrier Tractor

The Hefty G is a tool carrier tractor produced between 1974 and 1978 in Juneau, Wisconsin, USA. Designed for versatility in agricultural and specialty applications, this two-wheel drive machine is characterized by its compact dimensions and functional design.

Engine and Performance

The tractor is powered by a liquid-cooled, 4-cylinder Continental R800-46 gasoline engine. With a displacement of 51.6 cubic inches (0.8 liters), it produces 27 horsepower (20.1 kW) at a rated engine speed of 3300 RPM. The engine utilizes an 8:1 compression ratio and a 1-3-4-2 firing order.

Transmission and Drivetrain

Power is delivered through a gear-type transmission providing 6 forward speeds and 1 reverse gear. The drivetrain features a mechanical dry disc clutch and a standard two-wheel drive configuration. Steering is manually operated, with optional power steering available for improved handling.

Hydraulics and PTO

The hydraulic system is an open-center design, delivering a pump flow of 3.2 gpm (12.1 lpm) at a pressure of 2000 psi (137.9 bar), supporting up to two valves. The tractor includes an independent rear PTO capable of 540 and 1000 RPM, along with an optional mid-mounted PTO, allowing for the operation of various implements.

Dimensions and Chassis

The chassis features a multi-position front axle, allowing for a wheelbase adjustment ranging from 75 to 89 inches (190 to 226 cm). The tractor has a shipping weight of 2100 lbs (952 kg). Adjustable front and rear treads—40 to 60 inches and 36 to 62 inches respectively—provide flexibility for different row crop spacing requirements.

Conclusion

The Hefty G serves as a specialized tool carrier suitable for operators requiring a compact, maneuverable tractor with adjustable tread widths for specific field tasks. Its straightforward mechanical design and independent PTO options make it a reliable choice for light agricultural duty.
