A skid steer brush cutter is one of the most job-winning attachments you can own. It handles work a bucket can't touch, gets into areas a tractor won't fit, and turns overgrown fields, fence lines, and brushy lots into cleared, usable ground in a fraction of the time it would take by hand.
But buying the wrong one costs you money twice: once when you buy it, and once when it doesn't perform on the job.
This guide covers everything you need to match the right skid steer brush cutter to your machine and your work.
Is a Brush Cutter the Right Tool?
Before anything else, know what a brush cutter is built for.
A brush cutter attachment excels at light to heavy brush, overgrown fields, tall grass, saplings, and most fence line work. It's the right call when you're clearing acreage, managing trail systems, cleaning up development lots, or maintaining right-of-way.
It is not a forestry mulcher. If you're working standing timber or stumps over 6 inches regularly, a mulcher is the right tool. Brush cutters have material limits, and running them past those limits destroys blades and motors.
Know your job type before you buy.
Flow Requirements: The Number That Makes or Breaks the Purchase
Hydraulic flow is the single most important spec when choosing a skid steer brush cutter. If your machine doesn't make the flow the attachment needs, you won't get the performance. Period.
There are three flow tiers:
Low flow: 10-15 GPM. Compact and mini skid steers fall into this range. Not all brush cutters come in a low-flow configuration, so this matters if you're running a smaller machine. Standard flow: 16-26 GPM. Most mid-size skid steers hit this range. This is the most common configuration for residential and light commercial clearing work. High flow: 27 GPM and up. Full-size high-flow machines. This is where you get maximum cutting capacity and speed through heavy material.
Look up your machine's rated hydraulic flow before you shop. It's in your operator's manual. Mismatching flow to attachment is the most expensive mistake contractors make when buying brush cutters.
Open Front vs. Closed Front: What the Difference Actually Means on the Job
This is the second question you need to answer, and it's driven by your job conditions.
Closed Front Brush Cutter
A closed front brush cutter uses chain links across the front and back of the cutting deck. Those chains contain flying debris and keep it from launching into the operator zone or onto surrounding property.
This design is the right call when you're working near structures, roads, livestock, or people. Residential lots, fence lines near buildings, work adjacent to traffic. When flying debris is a liability, the closed front protects you.
The tradeoff: the closed deck limits material entry size. It's optimized for brush and grass, not for driving into heavy saplings.
SSN carries the HD Closed Front Brush Cutter in 66", 72", and 78" widths, with low-flow (10-15 GPM) and standard-flow (16-26 GPM) options.

Open Front Brush Cutter
An open front design removes the front barrier, letting you drive directly into material. This gives you more aggressive entry into thick brush, saplings, and dense growth. The right open-front cutter can handle trees and brush up to 6 inches in diameter.
This is the tool for large-scale clearing where debris containment matters less than throughput. Field clearing, trail building, development site prep, right-of-way maintenance. When you're clearing acreage and not worried about what's behind you, the open front moves more material faster.
SSN carries open-front cutters in 72", 78", and 84" widths in standard-flow and high-flow configurations.
Sizing: Width vs. Machine Capacity
Wider is not always better.
A wider brush cutter covers more ground per pass, which means fewer passes per acre. But your machine has to be able to power and carry it. An oversized cutter on an underpowered machine will either underperform or create stability issues.
General rules:
- Mini skid steers: 60" or smaller - Mid-size skid steers (standard flow): 66" to 72" - Full-size skid steers (standard to high flow): 72" to 84"
Match the cutter width to the rated operating capacity and hydraulic flow of your specific machine, not a general category. Two machines in the same size class can have meaningfully different flow ratings.

What a Brush Cutter Can and Can't Handle
Setting realistic expectations saves equipment and keeps jobs on schedule.
A brush cutter handles: - Grass and tall weeds up to several feet high - Brush and briars up to 3-4" diameter (closed front) - Saplings and brush up to 6" diameter (open front, high flow) - Overgrown fence lines and lot clearing - Trail maintenance and right-of-way work A brush cutter does not handle: - Standing hardwood timber - Root balls and stumps - Rocky terrain (destroys blades fast)
If your job has a lot of stumps, pair your brush cutter with a root grapple for cleanup and a stump grinder for what's left in the ground. The combination covers the full clearing job.

Before You Buy: Questions to Answer
1. What is your machine's hydraulic flow (GPM)? 2. Are you working near structures, roads, or people? (Closed front vs. open front) 3. What size material will you be cutting regularly? 4. How many acres per week are you clearing?
Those four answers will tell you which brush cutter belongs on your machine. If you want to talk it through, contact us with your machine specs and we'll point you to the right option.
