TRANSMISSIONS OVERVIEW

The McCormick Intl MB85 tractor features a versatile 12-speed or 24-speed transmission system, providing enhanced flexibility for various agronomic tasks. The option for a higher gear range allows for greater efficiency in transport operations, while lower gears improve torque for plowing or heavy-duty fieldwork. A potential challenge may arise in optimizing gear selection for diverse activities, requiring operator experience to maximize productivity.

Description 12-speed/24-speed

TRANSMISSION 1

The McCormick Intl MB85 features a 12-speed gear transmission, offering flexibility in various field conditions and optimal power delivery for tasks ranging from tilling to hauling. The wide gear range allows for efficient speed modulation, enhancing both fuel efficiency and operational versatility. However, the complexity of managing more gears may require additional operator training to maximize performance.

Gears 12 forward and reverse

TRANSMISSION 2

The McCormick Intl MB85 features a versatile transmission with 24 forward and 12 reverse gears, allowing for precise speed control in varying field conditions which is advantageous for tasks requiring different operational speeds. However, the complexity of the gear system may present a learning curve for some operators. This extensive gearing setup is particularly beneficial for heavy-duty applications such as plowing or transport over varied terrain.

Gears 24 forward and 12 reverse

MECHANICAL

The McCormick Intl MB85 tractor features optional 4WD for enhanced traction on uneven terrain, making it ideal for various agricultural applications. Its hydrostatic power steering provides superior maneuverability, while the mechanical wet disc brakes ensure reliable stopping power under load. The choice between 12-speed and 24-speed transmissions allows operators to optimize performance based on task requirements, though the complexity of a more extensive transmission system may require additional maintenance considerations.
