FAQ’S

The HPX14 is designed for 13–20 ton mid-sized excavators.

Up to 14 inches (36 cm).

Yes. Each HPX shear uses grapples to maintain control of the tree so the operator can place it safely. The HPX14 has a dual grapple configuration. (Twin shear arms with dual grapples.)

It depends on the model and whether you have rotation. Generally, the range for HPX14 is 15–25 GPM @ 3,500 PSI for standard; rotation models add a second circuit.

The HPX14 has optional 60° rotation to better align with trees on uneven ground.
