The Maxx Attachments Timberwolf skid steer tree shear, on a universal quick attach mount, cuts trees up to 16" in diameter and holds them with dual grapple arms before the cut, 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.

This listing covers four shear models, each available with five attachment control device options:
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. If you are unsure which connector your loader uses, call us at (866) 757-8337 before ordering.
Compatible with skid steer loaders and compact track loaders equipped with 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.
The 14" models shear trees up to 14" in diameter and need a machine with at least 3,000 lbs of operating capacity. The 16" models handle up to 16" and require 3,400 lbs. If your loader is near the 3,000 lb line, the 14" is the safe choice — the 16" adds 300 lbs of attachment weight on top of the higher capacity requirement.
The accumulator arm holds a sheared tree while you cut the next one, letting you build a bunch of several stems before carrying them out. If you are production-thinning or harvesting and making many trips, it pays for itself in reduced travel. For occasional clearing where you handle one stem at a time, the standard grapple model is enough.
All four models run on 15-30 GPM at a maximum of 3,000 PSI — standard flow on most skid steers and compact track loaders. No high-flow package is required. The shear ships with hoses to machine lines and flat-face quick disconnects.
Match it to your machine's auxiliary electrical connector: 7-Pin for Bobcat, 8-Pin for Caterpillar and ASV/TEREX, 14-Pin for Bobcat, John Deere, Kubota and others, and a separate 14-Pin option for Caterpillar High Flow machines. Standard Switch Controls are available if your machine has no compatible harness. Check your operator manual or call us if you are unsure.
The Timberwolf mounts to any skid steer or compact track loader with a Universal Quick Attach plate. Compatibility is determined by mount type rather than brand, so confirm your machine has a universal quick attach configuration and meets the operating capacity requirement — 3,000 lbs for 14" models, 3,400 lbs for 16".
The 3/4" AR400 high-tensile blades can reach up to 2,500 hours of use when maintained properly. They are designed for straightforward replacement — the improved blade adjustment and stop mechanism means adjustment and swap-out are done in the field rather than at a shop.
The hydraulic system uses larger lines and a larger rod diameter in the shear cylinder, which reduces pressure loss through the circuit. Combined with the 5" barrel and 3" rod cylinder, that produces a 33% increase in shear speed over the previous design.
Maxx Attachments is the current name for the former Dymax attachment line, now manufactured and supported by Maize Corporation. If you have run a Dymax shear before, this is the same product family under the Maxx brand — which is why the part numbers still carry a DX prefix.
Yes. The Timberwolf is a forestry shear built for production harvesting across species. If your work is specifically pasture cleanup in cedar and juniper, the 20" Ranch Axe is purpose-built for that; for mixed forest work including hardwood, the Timberwolf is the right tool.
