Manually Adjustable Discharge Doors

Manually adjustable discharge doors on both sides regulate the volume of discharged material. Thick plating reinforces the doors for long lasting performance.

Dual Direction Rubber Conveyor Belt

Dual direction rubber conveyor belt is heavy-duty with a raised chevron tread and adjustable tension belt. Dual direction drive boosts productivity by eliminating the need for awkward maneuvering commonly encountered in tight areas.

High Torque Agitator

High torque agitator assembly is directly powered by an independent hydraulic motor. Motor and conveyor systems rotate in conjunction on bi-axis planes for consistent flow and to prevent material from bridging inside the bucket.

Dual Direct Drive Hydraulic Motors

Dual direct drive hydraulic motors drive the belt and a third motor drives the agitator providing consistent hydraulic flow. Motors are externally mounted for convenient access.

Welded-On Serrated Safety Step

Welded-on serrated safety step allows for easy entry and exit from the cab.

Tool Mounted Operation and Maintenance Manual

Tool mounted operation and maintenance manual required for proper operation of the work tool attachment is sealed from the elements.
