Henderson Products under tailgate spreaders are a magnificent piece of equipment to have in those hard winter months. 6″ augers have bi-directional flighting to feed materials from both sides of the trough and are direct drive and powered by a high toque, low speed 18.7 CIR hydraulic motor. 9″ augers have continuous flighting and direct driven by a high torque, low speed 45.6 CIR hydraulic motor. Under tailgate spreaders have built in safety measures to prevent injury. The safety interrupt is built in and automatically shuts down the flow of hydraulic fluid when the trough door is open. Easily remove and mount an under tailgate spreader with the use of the Henderson quick detach pins. The Henderson FSH is a heavy duty slide in, large capacity spreader system. This system can be run on hydraulics with the use of an electric motor or stand alone diesel engine. Each model has a 24″ conveyor with cross bars dependent on the model purchased. Each conveyor is protected by a bolt in shield. The spinner chute assembly is 100% enclosed and manufactured of 10 gauge steel. The hydraulic motor is enclosed inside the chute to maximize material flow.
