Operators could select either a 20-speed gear transmission with 4 reverse ratios or a 12-speed full power shift transmission with 2 reverse ratios. The drivetrain features articulated power steering and hydraulic disc brakes to manage the machine's 17,900 kg weight effectively.
Hydraulics and Dimensions
The hydraulic system utilizes a closed-center design with a pump flow capacity of 113.6 liters per minute (30 gpm) at a pressure of 206.8 bar (3000 psi). It is equipped with three valves for implement control. The tractor measures 608 cm in length and 420 cm in width when fitted with standard dual tires, ensuring stability during operation.
