TRANSMISSIONS OVERVIEW

The McCormick Intl C70 features an advanced 8-speed synchromesh transmission, which allows for smooth gear transitions, enhancing operator comfort during operation. The inclusion of an 8-speed shuttle provides efficient directional changes, ideal for tasks requiring frequent forward and reverse motion, such as loader work. The 16-speed two-speed power shift option further optimizes performance for varying field conditions, but it may require additional operator training to maximize shift timings effectively.

TRANSMISSION 1

The McCormick Intl C70 tractor features a synchromesh transmission that provides smooth gear shifting across 8 forward and 4 reverse gears, enhancing operational efficiency and control. The dry disc clutch offers durability and straightforward maintenance but may require careful handling to prevent slippage under heavy loads. Ideal for various agricultural tasks, this tractor balances ease of use with robust performance, making it suitable for both small and medium-sized farms.

MCCORMICK INTL C70 TIRES

The McCormick Intl C70 tractor offers a 2WD option with standard agricultural tires, providing optimal traction for lighter tasks, but may struggle in soft or uneven terrain. The 4WD variant, with larger front tires (11.2-24), enhances stability and grip, making it ideal for heavier loads and challenging landscapes. Consider your operational needs: 2WD is suitable for flat, firm fields, while 4WD is advantageous in hilly or muddy conditions.
