Dymax 12" to 20" Excavator Tree Shears for Hydraulic Excavators

Dymax Excavator Tree Shear

A Dymax Excavator Tree Shear is the perfect tool for forest utility work, hazardous fuel removal from forest lands, plantation thinning of acacia and eucalyptus, biomass fuels production and trimming limbs and trees for roadside maintenance and site development or alongside railroad tracks.

In plantation thinning operations of Acacia and Eucalyptus a Dymax Excavator Tree Shear can average between 100 to 180 trees per hour cutting rates and produce more volume of wood than competing models.  Cutting rates are subject to tree spacing and operators.

The Dymax Tree Shear features two-shear arms with replaceable high strength, abrasion-resistant steel cutting knives.  The dual shear arm design delivers stronger performance in tough applications such as hardwood shearing compared to single shear arm models that are prone to twisting and bending.

All Dymax Tree Shears for Excavators feature dual grapple arms that secure the tree prior to shearing. 

Options include a bunching arm gatherer that cuts multiple stems in specific operations and a hydraulic tilt rotator that provides side to side tilt, allowing operators to adjust to the tree trunk or limb when working on uneven ground.
