This leaf/grass blower was manufactured specifically as a tractor mounted, three point hitch unit and powered by tractor power take off which drives a blower fan for leaf/grass suction removal (suction uptake unit not part of this offer and not available). Leaves/grass then blow back from blower discharge into a towed trailer (no available) towed behind the blower unit. Blower unit has trailer hitch attached to frame of blower for trailing wagon hook-up. Blower and associated housings are in very good condition as is the power take off shafting and safety guard. Blower unit and frame were manufactured by DURST (producer of furnace blowers). Photo shows only name plate data available. No operator manual. No leaf/grass trailer. and No suction and exhaust piping from intake or discharge of the blower. Had intended to use the tractor mounted blower for accelerating composting of farm wastes and never had time to try to make it work.
