Cab & Controls

All controls are located in a 30° arc forward and to the right of the operator. The enclosed cab has a fully adjustable, cloth-covered suspension seat as standard and comes with a 3" (76 mm) seat belt. Located forward of the operator are the engine oil pressure, coolant temperature, and fuel level gauges, along with the transmission gear indicator and a multi-function Contronic monitoring display. In the fully adjustable steering pedestal, you will find the following switches: differential lock/unlock, hazard lights, combination turn signal, horn, and high beam headlight. Heater and wiper/washer controls (if equipped), as well as lighting and accessory switches, are grouped in the operator’s right-hand console. This console contains the ignition key, accelerator/decelerator foot pedal, and slider-type hand throttle, which are standard equipment. Additionally, outside mounted rear view mirrors (left and right) and an exterior interior mirror are standard. Interior operator noise levels average 75 dB(A) per ISO 6394 (enclosed cab).
