A true workhorse built tough for industrial and commercial applications. These bad boys clear brush quickly and efficiently to improve your ROI and increase your profit. You can rely on these cutters to consistently tackle heavy brush and trees up to 8” in diameter. The unique open front “v-notch” design allows for increased operator precision cutting of trees and saplings. Tip speed and torque are optimum for efficient cutting with a massive 1” blade carrier and three high-tempered steel drop blades. But don’t just take our word for it, watch a dealer’s review.

Number of Blades

(3) 0.5 x 4 in; non-updraft

Blade Type

High-tempered non-updraft steel blades to cut and discharge material quickly.

Blade Carrier

1” GRD-50 disc.
All Brush Wolf blade carriers are CNC balanced for ultra-smooth operation.

Drop blade

Long-Lasting Blades

The Brush Wolf industrial-strength drop-down blades are heat treated, have a milled edge, and are Supertuf coated to stand the test of time.


Direct-Drive Piston Motor

Experience the power of the direct-drive SAI® radial piston motor. With higher torque, you’ll get more cutting power, quicker recovery time, and less bogging down when accelerating through thick brush.


Massive Bearing Housing

We pair our direct-drive radial piston motor with a robust Eskridge® bearing housing that has a 2.625” shaft diameter and patented shaft retention system.


Motor Protection

Pressure Relief Valves: Added pressure relief valves safeguard your motor from pressure spikes and allow for a faster shutdown.


Gearbox Seal Protection

A welded seal guard collar prevents wire, twine, and vegetation from wrapping around and damaging the gearbox.


Ultra-Rugged Deck Frame

Here’s why our brush cutters last for life. We build each deck frame from a single piece of formed 1/4" thick heavy-duty steel, never pieced together. This means our frames are consistently better made and more durable, with the elimination of construction errors and frame failure. One-piece frames will always provide superior strength.

Clean deck design

Clean Deck Design

Our one-piece deck frame construction creates a “clean deck” design that allows material to glide off, preventing unwanted debris buildup. (Think less mess and easier to clean.)


Seam Welding

Unlike our competitors, Brush Wolf’s deck and frame construction is fully boxed and continuously welded across each seam for an indestructible, rust-proof support structure.

Boxed-in gusset

Reinforced Gussets

We went above and beyond to make sure our cutters are crazy strong by adding boxed-in gusset reinforcements, extra bracing, and supports.

Powder coating cutters

Powder-Coated Tough

Protected with the most durable finishing process, we powder coat every part to minimize rust, resist scratches, and prevent fading, so you get more life out of your brush cutter.

Brush cutters power coated tough

Push Bar

Let’s help “feed” the cutter with a welded push bar to knock down taller vegetation and trees and enhance the cutting capabilities.


Slotted Front Shield

Slotted front shield provides increased visibility while protecting the operator from debris.

Blade Access Cover

Blade Access Cover

Easy access to the blade bolts for quick blade replacement.

Couplers and dust caps

Plug + Play Ready

Everything is ready to go upon delivery with the included quick-connect couplers, 114" hydraulic hoses encased in protective wrap, and dust caps to prevent line contamination.

Hose routing system

Advanced Hose Routing System

We took the time to devise a well-thought-out hose routing system based on real-life situations. Using guides and STAUFF clamps, our hydraulic lines can be routed to either side. So, you choose which side works best for your machine.



The vented hood fully encloses the motor and drive components to shield them from damaging impacts and debris.

Safety Steps

Enhancing safety is our thing, so we added two non-slip, serrated metal steps for easy in and out.

Universal Quick Attach System

Time is money, so we made sure our cutters attach quickly to your machine by using the industry-standard Quick Attach system. It will only take seconds to attach/detach your machine with our universal pick-up plate.
