Tractor Orientation

Overall Description

The Models 435, 485 and 535 tractors are classified as 4–wheel drive articulating vehicles.. The tractors consist of front and rear frame assemblies which steer by pivoting at the center articulation joint..

The front frame, (1) incorporates the engine, fuel tanks, transmission, front drive axle, and cab.. The rear frame, (2) incorporates the rear drive axle and supports any implements that are operated by the tractor.. This type of design allows for greater flexibility of weight distribution, depending upon operating conditions and type of implement.. The operator can ballast the tractor to best suit the needs of the particular operation..

The construction of the tractor is a modular-type construction.. This means that the major components are individual units which are supported within the front and rear frames.. This makes for easier serviceability and longer life due to reduced structural stress on components..
