The RETRO SPIDER mounted mulcher for excavator is specially designed to shred pruned branches, small trees and debris from tree-felling and scrub clearing. Its design enables it to be mounted onto any model of excavator or backhoe. It is equipped with a rotor with 360º swinging hammers (3 rows). The special positioning of the hammers on the rotor produces very fine shredding and the shredded material is evenly spread over the terrain. Skid runners for height adjustment. Manually controlled hinged hood. Very solid and sturdily built.
