FAQ’S

What size excavator is this tree shear designed for?

The HPX10 is designed for 8–14 ton hydraulic excavators.

What is the maximum cutting diameter?

Up to 10 inches (30 cm).

Does it hold the tree after the cut?

Yes. Each HPX shear uses grapples to maintain control of the tree so the operator can place it safely. The HPX10 has a dual grapple configuration. (Twin shear arms with dual grapples.)

What hydraulic flow and pressure are required?

It depends on the model and whether you have rotation. The HPX10 is typically 15–25 GPM with max 3,000–3,500 PSI depending on configuration; rotation adds a second circuit and may require a drain line.
