Dymax HPX Tree Shears for Hydraulic Excavators:

A Dymax HPX Hi Performance Excavator Tree Shear is the perfect tool for forest utility work, hazardous fuel removal such as dead undergrowth or diseased trees 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 operator skill.

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

Available in 8, 10, 14, 16, 18 and 21 inch diameter cutting capacity.

All Dymax HPX Tree Shear features dual grapple arms that secure the tree prior to shearing.  An optional 60 or 180 degree hydraulic rotator provides efficient positioning for side trimming along roadways and improves operators ability to load chippers in congested worksites.

Available in 8, 10, 14, 16, 18 and 21 inch diameter cutting capacity.
