The conveyor chain is driven by a hydraulic motor with a 20:1 worm gear box. The spinner is powered by a direct mount hydraulic motor. An 18 in. poly spinner casts material 2 ft to 30 ft. The spreader is available with a regular or extended chute. Two adjustable baffles allow you to cater the spread pattern to your use. The chute and spinner assembly flips up or detaches completely, tool-free, for convenient bulk unload, easy servicing, and access to towing. Hydraulic spreader controls are sold separately.
