MECHANICAL
The McCormick Intl C90 features a robust 4x4 MFWD option, which enhances traction in uneven terrain, making it suitable for diverse agricultural applications. The 8-speed synchromesh transmission provides smooth gear shifts, whereas the 16-speed power shift offers versatility for varying load conditions but may require more operator skill. The two-post ROPS cab design minimizes visibility obstruction but may offer less protection compared to a full cab during adverse weather conditions.
