Excavator tree shear

Product Overview
A stump shear designed for excavators uses a fixed jaw combined with a hydraulic cutting blade to slice through hardwood roots and separate stumps with minimal pull force. Compared with ripping or pulling methods, a dedicated hydraulic stump shear reduces stress on the boom and lowers fuel consumption while increasing clearing speed.

Field Tips

• Begin by slicing the outer roots with the side teeth before attacking the stump center to preserve blade edges.
• When roots are embedded in rocky soil, use the side teeth to rake away loose stones ahead of the main cut.
• In hard clay, moisten the ground around large stumps the night before to ease cutting.

How to Match an Excavator Stump Shear to Your Machine Size

• Mini & Compact Excavators (1.5–6 t): suited for light landscaping and residential clearing.
• Medium Excavators (7–20 t): recommended for farm clearing and medium construction sites.
• Heavy-Duty Excavators (21–35+ t): intended for commercial forestry and large land development.

Applications / Where the Attachment Delivers Maximum ROI

• Commercial forestry: split thick stumps quickly for replanting or processing.
• Farm land clearing: cut deep taproots cleanly while preserving topsoil.
• Road and utility construction: remove roots along right-of-ways while protecting buried services.
• Wood recycling and chipping preparation: reduce large stumps to manageable pieces prior to chipping.

Field Case — Reported Performance Results

• In one field report, stump clearing increased from 4 to 11 stumps per hour on a 20 t excavator after switching from a ripper tooth to a heavy-duty hydraulic stump shear.
• Total fuel consumption in the reported case decreased by about 25%.
• The project finished 8 days ahead of schedule, reducing labor costs by approximately 35%.

Frequently Asked Questions (Q&A)

• What is the difference between a stump shear and a stump grinder? A stump shear slices and pulls roots during land clearing; a stump grinder reduces stumps to chips or sawdust and is better for finish-grade urban work.
• What root diameter can an excavator stump shear handle? Capacity depends on cylinder force and machine size; medium and heavy units commonly handle hardwood roots around 30–50 cm in diameter depending on model.
• Is blade maintenance difficult? Shears are built with high-strength wear plates; worn cutting edges can be welded or replaced on site to minimize downtime.
