A skid steer loader has a rear mounted engine and a tailgate that pivots about a vertical axis, and the tailgate in turn carries an engine cover panel that is pivoted to the tailgate about a horizontal axis. When the tailgate is closed, the engine cover panel overlies the loader engine and other components for the skid steer loader, and provides protection and covers such components. The engine cover panel is made so that it will move upwardly for access to the components and swings away with the tailgate for access to the engine compartment.

A track driven machine has a pair of track frames on opposite sides thereof, and each of the track frames has a pair of laterally extending arms fixed thereto. The arms are joined to a machine frame only through vibration isolating elastomeric blocks that carry compression loads from the arms to the machine frame. The elastomeric blocks are held in place with bolts that pass through openings in the machine frame. There are second elastomeric blocks above each of the first blocks to support downward movement of the arms relative to the machine frame.

A track frame or undercarriage is made to support a rubber track on suitable guide rollers. A tensioning roller is provided as one of the guide rollers on the interior of the track and is mounted on a pivoting bracket. The pivoting bracket moves the tensioning roller to a working position for creating tension in the track. An actuator provides a known force on the pivoting bracket to move the tensioning roller to its working position, using a controlled pressure applied to the actuator. Drive sprockets for the track are mounted onto a drive case that is mounted to the frame through pivoting linkages such that the drive case and the drive sprocket can be held in a working position and retracted away from the track. The position of the tensioning roller is maintained within set limits of retractions during use, by providing a stop to limit the amount that the tensioning roller can retract.

A work machine includes a frame supported for movement over the ground, a prime mover for driving movement of the frame, an operator compartment supported on the frame and a cradle coupling the operator compartment to the frame. The cradle is pivotable between an operating position and a service position and includes a biasing mechanism for biasing cradle toward the service position and an isolation mount coupling the operator compartment to the cradle. The isolation mount permits deflection of the operator compartment relative to the cradle along a selected axis. A latch mechanism releasably couples the cradle to the frame and a handle is provided for actuating the latch mechanism. The isolation mount includes a deformable member having a void defining the selected axis. The axis can be aligned with a force exerted on the cradle by the operator compartment to reduce stress on the biasing member.

A combined liquid tank and fan air flow housing is molded as a unit to combine needed functions in a compact preassembled unit. Separate spaced side tank portions are formed that are joined together with a front end tank to form a central opening with upper and lower ends. The opening is closed with a top plate that defines a plenum chamber and a lower fan support plate that forms a fan chamber in the central opening. A fan in the fan chamber creates an airflow from the exterior through the plenum chamber and out lateral ducts formed in the side tank portions. The inlet air flows through an oil cooler, water radiator and if desired, an air conditioner condenser in the plenum chamber. The tank formed is used for storage of hydraulic fluid.

A speed reduction drive is used with a crawler track that is an endless member mounted on suitable supports including a ground engaging portion for moving a vehicle attached to a track frame. The speed reduction drive comprises a drive case having an input shaft and an output shaft. The output shaft has a pair of track drive wheel sections mounted on opposite ends thereof that protrude out from the drive case. The input shaft has a sprocket drivably mounted thereon and carrying a chain that drives a sprocket on the drive shaft. The input shaft is driven with a hydraulic motor and has a normally spring-applied pressure released brake on the input shaft. The track drive wheel sections have bars or drive elements that engage lugs on the track to effect the driving arrangement when the track drive wheel sections are rotated.
