Introduction
McCormick GX45 Compact Utility Tractor
The McCormick GX45 is a compact utility tractor produced between 2002 and 2007 by McCormick International, a division of Argo. Designed for versatility in agricultural and groundskeeping operations, this series offers a range of transmission and configuration options to meet various operational requirements.
Engine and Performance
The tractor is powered by a 2.0-liter, 4-cylinder Yanmar liquid-cooled diesel engine. It delivers a gross power output of 44 hp (32.8 kW) and a net power of 40 hp (29.8 kW). The engine utilizes direct injection and operates at a rated speed of 2800 RPM, producing 88.5 lb-ft (120.0 Nm) of torque at 1600 RPM.
Transmission and Drivetrain
The GX45 provides three transmission configurations: a hydrostatic transmission for infinite speed control, a 12-speed synchronized shuttle, or a 16-speed synchronized shuttle with a creeper gear. The mechanical dry disc clutch is standard for the shuttle models, while hydrostatic versions feature an electro-hydraulic wet disc clutch. It is available in both two-wheel and four-wheel drive variants.
Hydraulics and PTO
The hydraulic system utilizes an open-center design with a total flow of 10.3 gpm (39.0 lpm), supporting up to three remote valves. The rear lift capacity is 2646 lbs (1200 kg) with position and draft control. The PTO system includes a live rear PTO (540/750 rpm), with optional mid and front PTO configurations available for increased implement versatility.
Operator Environment and Dimensions
The operator station features a two-post foldable ROPS as standard, with an optional air-conditioned cab available. Steering is managed by a hydrostatic power system, and stopping power is provided by wet disc brakes. The tractor measures 134.7 inches in length with a ground clearance of 14.6 inches.
Conclusion
The McCormick GX45 serves as a highly adaptable utility tractor suitable for small-to-medium scale agricultural tasks, specialized maintenance, and property management. Its combination of multiple transmission choices, flexible PTO options, and optional front-end equipment makes it well-suited for varied operational environments.
