The device is a RoGator 418, a self-propelled, off-road agricultural working machine from model year 2005, featuring a Caterpillar 3056E engine and hydrostatic drive. This operator's manual provides instructions for its safe operation and maintenance.
Function Description
The RoGator 418 is designed for agricultural tasks, featuring a hydrostatic drive system that controls vehicle speed by regulating oil flow to the wheel motors. The machine can operate in "Field" or "Road" positions, with different control mechanisms for speed. In "Field" position, speed is controlled by the hand throttle, while in "Road" position, it's determined by the accelerator pedal. The machine also features 4-wheel steering, which can be engaged for enhanced maneuverability, particularly on headlands, and disengaged for driving in tramlines or on public roads.
