Choosing the Right Flail Mower Size: From 48″ to 72″ – What Fits Your Tractor Best?
Flail Mower vs Brush Hog: Which Mower Fits Your Land Best?
When you’re shopping for land-clearing equipment, two machines often come up: the flail mower and the brush hog (also known as a rotary cutter or bush hog). Both are designed to handle terrain and vegetation that’s far too dense for a standard lawn mower, but they each have distinct strengths depending on how and where you mow.
If you're new to tractors and PTO-powered attachments, this guide will walk you through the differences in clear, non-technical language — helping you make the best decision for your acreage.
What Is a Brush Hog?
A brush hog, or rotary cutter, is a rough-cut mower that uses large, swinging blades to chop down tall grass, overgrowth, and even small saplings. It’s a favorite tool among farmers and landowners looking to clear large areas quickly.
Pros:
-
Covers large fields fast — great for one-pass mowing
-
Simple construction means fewer things to maintain
-
Works best on flat fields and open brush zones
Cons:
-
Leaves a rougher cut, not suitable for yards or parks
-
Can throw debris when hitting rocks or branches
-
Less safe around structures, livestock, or fences
If you’re clearing acreage with a John Deere or any tractor with more HP, a brush hog (or rotary mower) is perfect for large-scale clearing jobs. Some models can even be used with skid steers using the right adapter.
What Is a Flail Mower?
A flail mower uses multiple small blades — often called Y blades or hammers — mounted on a horizontal drum. As the drum spins, the blades "flail" outward, shredding brush, stringy stuff like vines, and grass into a fine mulch.
Pros:
-
Produces a nicer finish than most rough cutters — close to a finish mower look
-
Much safer on rocky or uneven terrain
-
Excellent for slopes, fence lines, ditch banks, and tight corners
Cons:
-
Slower mowing speed compared to rotary cutters
-
Slightly more complex with more moving parts to inspect
While brands like Maschio flail mower are well-known in Europe, Farmry offers comparable build quality and heavy-duty designs at a better value for American landowners.
Flail Mower vs Brush Hog: Key Differences
Feature | Flail Mower | Brush Hog (Rotary Cutter) |
---|---|---|
Cut Quality | Clean cut – like a finish mower | Rough cut – good for trails & saplings |
Debris Control | Safer – flails throw debris downward | Risk of flying objects if hitting rocks |
Terrain Handling | Great for wet areas, ditches, slopes | Best for flat, open ground |
Blade Type | Individual Y blades or hammer blades | 2–4 large swinging blades |
Maintenance | More blades, but easy one-by-one replacement | Fewer parts, simpler structure |
Speed | Slower but more controlled operation | Fast for large-scale mowing |
Tractor HP | Suitable for lower to mid-range HP | Often needs more HP |
Mounting | Usually quick hitch compatible | Standard 3-point or drawbar hitch |
Which One’s Right for You?
✅ Choose a Flail Mower If:
-
You want a cleaner cut and nicer finish
-
You work near fence lines, buildings, or on uneven terrain
-
You're mowing areas with stringy stuff, vines, or debris
-
Your tractor has a PTO shaft and 20–50 HP
👉 Farmry’s flail mower collection includes heavy-duty models with adjustable cutting height, replaceable blades, and quick hitch compatibility.
✅ Choose a Brush Hog If:
-
You need to mow large fields in fewer passes
-
You don’t mind a rougher, uneven finish
-
You're dealing with dense brush or small trees
-
You own a skid steer or tractor with high horsepower
Note: Most rotary mowers include a slip clutch or shear bolt to protect the gearbox when encountering hidden stumps or rocks.
Bonus Tips Before You Buy
-
Check your HP: Make sure your tractor isn't HP limited by the mower width.
-
Think terrain: Flails are safer for rocks and tight turns; rotary cutters rule large, open ground.
-
One-pass or multiple? Flail mowers offer more control; brush hogs give speed.

FAQs
Q: Can a flail mower handle brush and vines?
Yes. Farmry’s heavy-duty flail mowers are designed to cut brush, vines, and grass up to 1.5" thick, even in rough terrain.
Q: Which mower is easier to maintain?
Brush hogs are simpler in design, but flail mower blades are easier and cheaper to replace one at a time — especially if you hit something unexpected.
Q: Will either mower work with my tractor?
As long as your tractor has a PTO shaft and falls within the rated HP, either mower will work. Farmry models are available for both Category 1 and 2 tractors, with quick hitch compatibility available.
Final Thoughts: Choose Based on How You Mow
Both tools are excellent — the difference comes down to how you mow and what your land needs.
If you want a fast and rough option, go with a brush hog.
If you need safer mowing, a cleaner finish, and better maneuverability, a flail mower is the clear winner.
