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.
Articulation - The ability to steer by pivoting
