Timberwolf Forestry Grapple Tree Shear Attachment - Maxx Attachments

📘 Overview

The Maxx Timberwolf is a skid steer tree shear with grapple arms that hold the stem before and through the cut, on a universal quick attach mount. It cuts trees up to 16" in diameter, so felled stems land where you put them instead of where they fall. It is built for production forest harvesting — thinning, fire mitigation, and beetle-kill removal — where the operator is cutting all day and cannot stop to reposition every stem. Choose 14" or 16" cutting capacity, and choose between the standard grapple model and the bunching model, which adds an accumulator arm that holds a sheared tree while you cut the next one so you carry out full bunches instead of single stems. Sharp 3/4" AR400 milled knife edges cut cleanly and can reach roughly 2,500 hours of service when maintained, while the A-572 steel tower and internally routed, guarded hard lines keep the hydraulics out of the way of standing timber. The redesigned hydraulic system uses larger lines and a larger cylinder rod to cut pressure loss, yielding a 33% increase in shear speed over the previous design. Every model runs on standard 15-30 GPM flow at up to 3,000 PSI, needs 3,000 lbs of machine operating capacity for 14" models or 3,400 lbs for 16", and arrives with hoses and flat-face quick disconnects ready to plug into your machine.

⚙ Key Features of the Timberwolf Tree Shear

• 3/4" AR400 milled knife edges — high-tensile shear blades rated for up to 2,500 hours of use with proper maintenance.
• Dual grapple arms — secure the tree before the cut so you control which way it falls and where it lands.
• Bunching accumulator arm (bunching models) — shear one tree and hold it while shearing another, so you move full bunches instead of single stems.
• Solid cast shear arms on 14" models — 16" models step up to high-strength A572 fabricated arms for larger-diameter timber.
• Improved blade adjustment and stop mechanism — adjustment is quick and blade replacement is a bolt-out job, not a shop visit.
• Upgraded hydraulic system — larger lines, reduced pressure loss, and a larger cylinder rod deliver a 33% increase in shear speed.
• 5" barrel, 3" rod shear cylinder — paired with the engineered frame and arm structure for a high shearing power ratio.
• Internally routed, guarded hard lines — hoses are protected from the abrasion and impact inherent in tree shearing.
• A-572 steel tower — high-strength structural steel throughout the load path.

🔑 Why Buy This Tree Shear with Grapple?

• Directional felling without a second machine — the grapple holds the stem through the cut, so you drop timber where you want it instead of chasing it after it falls.
• Fewer trips per load — the accumulator arm lets you build a bunch of several stems before carrying, cutting travel time on every cycle.
• 33% faster cycle times — the redesigned hydraulic circuit means more cuts per hour on the same machine and the same flow.
• Blade life measured in seasons, not weeks — 3/4" AR400 knife edges reach up to 2,500 hours, and bolt-on replacement keeps the machine working.
• Runs on standard flow — 15-30 GPM covers the majority of skid steers and compact track loaders without a high-flow upgrade.

Control device options: Standard Switch Controls · 14-Pin (Bobcat, John Deere, Kubota, Other) · 8-Pin (Caterpillar, ASV/TEREX) · 7-Pin (Bobcat) · 14-Pin (Caterpillar High Flow)

Select the control device that matches your machine's auxiliary electrical connector. Your operator manual lists the connector type with the auxiliary electrical circuit; if you cannot find it, choose Standard Switch Controls, which work on any machine without a compatible harness.

🔗 What Is a Tree Shear Used For?

• Forest harvesting and timber thinning
• Land clearing and lot preparation
• Fire mitigation and fuel reduction
• Beetle-kill timber removal
• Pasture reclamation and cedar control
• Right-of-way and utility corridor clearing

🚜 Which Machines Fit the Tree Shear?

The Timberwolf needs 3,000 lbs of machine operating capacity on 14" models and 3,400 lbs on 16" — the heaviest machine requirement in the Maxx shear line, so size the loader before you check the coupler. It fits skid steer loaders and compact track loaders carrying a Universal Quick Attach system, including:

Compatibility is determined by mount type, not brand — confirm your machine's quick attach configuration before ordering. This attachment requires 15-30 GPM auxiliary hydraulic flow at up to 3,000 PSI. 14" models require a minimum machine operating capacity of 3,000 lbs; 16" models require 3,400 lbs. Hoses and flat-face quick disconnects to standard flow lines are included. Select your configuration above and add it to your cart to order.
