Tailor application rates with stainless-steel spreaders that provide individual variable speed control for both the conveyor and the spinner. Powered by the truck's 12V electrical system, the units also have blast control for quick, extra-dense applications and a reverse switch to clear jams quickly and easily. Two models: the 6.5-ft. 635 with 1.50 cu. yd. hopper capacity, and the 8-ft. 835 with 1.80 cu. yd. capacity.
