A decelerator control system includes a first control member, a machine control device, an engine, at least one brake, and a transmission. The first control member is manually moveable and is adapted to produce a first operator control signal. The machine control device is adapted to receive the first operator control signal and responsively produce an engine control signal, a brake control signal, and a transmission control signal. The engine is adapted to receive the engine control signal and responsively control the speed of the engine. The brake is adapted to receive the brake control signal and responsively control an engagement of the brake. The transmission is adapted to receive the transmission control signal and responsively control an engagement of the transmission.

Decelerator system for a work machine

An apparatus and method for cooling a work machine is disclosed. The apparatus has a fan element located inside an engine compartment of the work machine in a horizontal orientation. The fan element draws external air from above the work machine into the engine compartment. A deflector directs the air through a plurality of cooling cores which are radially spaced about the engine compartment and interspersed with a plurality of core spaces. The apparatus can be cleaned by spraying fluid from the outside through the plurality of cooling cores, causing any trapped debris to fall to the bottom of the engine compartment, where it can be removed through a cleanout.

Cooling system for a work machine

An apparatus and method of cooling a work machine is disclosed. A work machine includes a frame, a plurality of ground engaging devices, an operator compartment, a work implement, an engine, and a cooling system. The cooling system includes a radiator, a rotating fan assembly, a rotating deflector, and a means for rotating the fan and the deflector. The rotating fan assembly includes a fan and is for drawing air in a first direction across the radiator. The deflector has a concave surface with a plurality of projections extending therefrom and adapted to draw air in a second direction as the deflector is rotated.
