Manufacturer of industrial brushcutters

DAV-450 brushcutters for mini-excavators

Description

Features of the DAV-450 vertical-shaft brushcutter: An industrial land clearing attachment with a hydraulic drive;; A vertical-shaft disc with two freely rotating knives;; Designed for use on 4- to 10-ton excavators, backhoes or other boom carriers with similar stability and hydraulic systems;; Designed for brushcutting applications where chipping is not required (precommercial thinning, land clearing in uninhabited areas, and recreational trail maintenance).

Like other models in the DAV product group, the DAV-450 uses vertical-shaft brushcutting disc technology with two freely rotating knives:: Low acquisition and operating costs, since the DAV cutting technology is simpler than that used in DAH […];; Low weight unit for installation on smaller carriers […];; Easy maintenance owing to smaller number of parts […];

The DAV-450 is also structurally reinforced for intensive use, and includes a patented disc protector, a fixed device consisting of parallel plates, which:: Prevents the knives from touching the ground, thereby reducing risk of damage to cutting tools […];; Directs debris sideways away from the operator’s cab […];; May be used as a support in moving obstacles or pushing the carrier […];
