About this product
Overview
This Bradco heavy duty skid steer brush cutter — the Ground Shark Heavy Duty (HD) — clears brush and hardwoods up to 7" in diameter on a skid steer quick attach, running on 20–34 GPM of auxiliary hydraulic flow. Available in 66" and 72" cutting widths, weighing 1,605 lbs. Minimum cutting height is 2.5". Bradco builds the Ground Shark in four duty grades and cutting capacity is what separates them — match the grade to the largest material you actually cut.
Key Features of the Bradco Heavy Duty Skid Steer Brush Cutter
- Patented retractable blade carrier — when the blade meets a tree it moves up and back, exposing the whole cutting edge.
- Blades machined from AR400 high strength steel for maximum life in hardwood.
- Sold as the GS66HD and GS72HD — a heavy duty brush cutter attachment rated a full 3" above the standard grade.
- A 7 inch brush cutter on standard flow, where the 10" grades need a high flow brush cutter circuit.
- Cuts material up to 7" in diameter — Bradco's published capacity for this grade.
- Requires 20–34 GPM of auxiliary flow, so it is matched to the machine rather than to a size class.
- Bolt-on replaceable skid shoes, so the wear part is a consumable rather than a repair.
- The motor and valve assembly are fully shielded, preventing contact with debris.
- A brush cutter for skid steer work, not a mower. The blades are built to sever standing material, not to trim grass.
Why Choose This Heavy Duty Skid Steer Brush Cutter
- The middle grade exists for a reason. At 7" capacity on 20-34 GPM it covers hardwood a standard-duty cutter would stall in, without demanding the 30-45 GPM the 10" grades need.
- Capacity is the whole decision. A cutter run past its rated diameter stalls, bogs the machine and shortens blade life — the grade exists to prevent that.
- Flow must match, not merely exceed. Too little flow and the cutter never reaches speed; the recommended range is the operating window, not a minimum.
- One attachment, many jobs. Buyers comparing a skid steer brush cutter for sale against a rental usually find the attachment pays for itself within a season of regular clearing.

Which Machines Fit This Heavy Duty Skid Steer Brush Cutter?
The Ground Shark Heavy Duty (HD) mounts on a standard skid steer quick attach, so fitment is decided by hydraulic flow rather than by machine brand. Your loader must supply 20–34 GPM at the auxiliary circuit.

Ground Shark Heavy Duty (HD) Questions, Answered
When is Heavy Duty the right choice over Standard Duty?
When you regularly cut material between 4 and 7 inches. The Standard Duty is rated to 4 inches; running it past that stalls the cutter and shortens blade life.
Do I need high flow for the Heavy Duty?
It runs on 20-34 GPM, which most standard-flow skid steers supply. The 10 inch grades need 30-45 GPM, which usually means a high flow machine.
What size material will the Heavy Duty (HD) cut?
Bradco rates this grade for brush and hardwoods up to 7" in diameter.
How much hydraulic flow does it need?
It requires 20–34 GPM at the auxiliary circuit. Flow below that range means the cutter never reaches working speed.
How do the four Ground Shark grades differ?
By cutting capacity and flow. Standard Duty cuts to 4" on 15-40 GPM, Heavy Duty to 7" on 20-34 GPM, and both High Performance and Extreme Duty to 10" on 30-45 GPM.
Will it fit my skid steer?
It mounts on a standard skid steer quick attach, so the mount is brand-agnostic. What matters is whether your auxiliary circuit supplies the required flow.
Is there a mini skid steer brush cutter in this range?
The Ground Shark grades are built for full-size skid steer loaders and compact track loaders on a standard quick attach. Mini skid steers have lower flow than these cutters need.
Is a used skid steer brush cutter for sale worth considering?
Blades, skid shoes and the motor are the wear items. On a used unit, check blade condition and whether the motor and valve shielding is intact — those are what a new brush cutter skid steer buyers choose is protecting.
What is the difference between a brush cutter attachment and a mower?
A skid steer brush cutter attachment severs standing woody material to a rated diameter. A mower trims grass. The blade design, deck thickness and flow requirement are all different.
