The Harper Straw Blower chops and applies straw for erosion control, bedding and mulching. The
depth of the cut is easily adjustable while in operation to handle a variety of materials* and conditions. The standard 30’ hose provides even layering and pinpoint placement. The hose is pliable
down to 20° F. Temperatures below 20° may cause polyurethane to crack when stretched. A 360°
directional spout is available for broadcast operations.
*NOTE: Do not shred cardboard with a Harper Straw Blower. The density of cardboard will cause
damage to the cutting knives and the rotor.
