ENGINE DETAIL

The McCormick Intl GM40 tractor is powered by a Yanmar 3TNV88 diesel engine, featuring a compact size with 1.6L displacement and efficient Tier III emissions compliance, making it suitable for smaller agricultural tasks. With a rated power of 35.5hp at 2800 RPM and a peak torque of 80 lb-ft at 1200 RPM, it offers adequate low-end torque for demanding applications like plowing or tillage. However, the relatively low displacement may limit its performance under heavier loads, necessitating careful management of operational expectations in rugged conditions.

TRANSMISSIONS OVERVIEW

The McCormick Intl GM40 tractor features either a 12-speed or an optional 16-speed creeper transmission, allowing for precise speed control and enhanced torque management in challenging terrains. The 16-speed creeper gear is particularly advantageous for applications requiring low-speed operations such as plowing or intricate fieldwork, improving maneuverability and reducing load stress on the engine. However, managing the additional speeds may require a learning curve for operators, impacting initial productivity.

TRANSMISSION 1

The McCormick Intl GM40 tractor features a 12-speed transmission, providing versatility in both forward and reverse operations, which enhances its adaptability for various tasks such as plowing, tilling, and handling materials. The extensive gear range can improve fuel efficiency and optimize power delivery depending on load conditions. However, the complexity of a 12-speed transmission may require more maintenance and operator training to ensure effective utilization in different scenarios.

Gears 12 forward and reverse

TRANSMISSION 2

The McCormick Intl GM40 tractor features a creeper transmission, allowing for enhanced low-speed operation, ideal for applications such as precision tillage or road maintenance. With 16 forward and reverse gears, operators benefit from versatile speed control, enabling efficient handling of diverse terrain and crop conditions. However, the complexity of multiple gears may require skilled operation to optimize performance and prevent gear mishandling.

MECHANICAL

The McCormick Intl GM40 tractor features a 4x4 MFWD (Mechanical Front-Wheel Drive) chassis, enhancing traction and stability across varied terrains. Its mechanical wet disc brakes provide reliable stopping power, though maintenance can be more complex than dry systems. The availability of a 12-speed or 16-speed creeper transmission offers versatility for precision work in tight spaces, making it ideal for tasks like tilling or planting in confined areas.

MCCORMICK INTL GM40 TIRES

The McCormick Intl GM40 tractor features a compact design with Ag front tires (200/70R16) and larger Ag rear tires (320/70R20), providing optimal traction and stability in diverse agricultural terrains. The front tire size enhances maneuverability, while the rear tire size delivers better weight distribution and increased pulling capacity, making it suitable for tasks such as tilling or hauling. However, the disparity in tire sizes may pose challenges in traction during steep inclines; optimal load balancing is essential for efficient operation.
