The engine has been moved to the rear of the hopper, replacing the counterbalance weight and providing easier access for maintenance and repairs.

Real time pressure gauges for all hydraulic functions. Charge pressure, forward and reverse drive pressure, work function hydraulic pressures. Many built-in system diagnostic functions, all available on the in-cab display. Warnings for low hydraulic pressure, high hydraulic pressure, hydraulic suction filter - time to change, hydraulic return filter - time to change. Engine diagnostics available as well.

The rear mounted Radar and Cameras greatly improve safety for the ground crew, as well as operator confidence when backing or even moving forward with left and right side mounted cameras.

The trough cover doors have been improved to actually seal. No more leakage from the top of the trough onto the machine. This is a major improvement.
