TRANSMISSION
The Allis Chalmers 6140 is equipped with a synchromesh transmission, offering 10 forward and 2 reverse gears for enhanced control during operation, making it suitable for varying field conditions and tasks. The 279.4mm dry disc clutch facilitates smooth engagement and disengagement, providing reliable power transfer, although it may require more maintenance compared to hydraulic systems. Its gear range is advantageous for both precision fieldwork and heavier towing applications, though operators should be aware of potential shifts during load changes.

MECHANICAL
The Allis Chalmers 6140 tractor features a versatile 4WD MFWD option, enhancing traction and maneuverability in various terrains, though the 2WD may limit its capabilities in challenging conditions. Its inboard planetary final drives provide efficient power transfer, while the mechanical rear differential lock offers improved traction under heavy load situations. The open operator station, complemented by an optional ROPS and canopy, ensures operator safety but may expose the user to environmental elements, making it less desirable for all-day operations in adverse weather.
