TRANSMISSION

The Kubota M5640SU tractor features a partially synchronized transmission with 8 forward and 4 reverse gears, enhancing operational versatility for various tasks. Its 275mm dry disc clutch facilitates smooth engagements and a synchronized forward-reverse shuttle in low range improves maneuverability, making it suitable for intensive agricultural operations. However, the oil capacity of 42.4 quarts may require regular monitoring to ensure optimal performance, particularly in high-load scenarios.

Gears	8 forward and 4 reverse
Clutch	275mm dry disc
Oil capacity	42.4qts / 40.1L
Description	Four gears in high, low, and reverse ranges. Synchronized forward-reverse shuttle shifting in low range, and synchronized shifting between gears 3 and 4.

MECHANICAL

The Kubota M5640SU's 4x2 configuration provides simplicity, but the optional 4WD enhances traction for challenging terrains, making it versatile during varied agricultural tasks. Differential lock standard at the rear improves stability and control in slippery conditions, while the hydrostatic power steering facilitates maneuverability, crucial for precision operation. However, the 8-speed partially synchronized transmission may present challenges in seamless gear transitions during rapid changes in speed or load, necessitating operator skill.
