Rotary Cutter, Box Blade, or Land Grader: Which to Pick
South Mississippi land needs different tools at different times. Here is how to match the right rear implement to the job before you buy.
Most folks who buy a tractor around Covington County already know they want something for the back. The question is usually which thing. A rotary cutter, a box blade, and a land grader all hang off the same three-point hitch, but they do completely different work. Getting the wrong one means a tool that sits while you borrow someone else's.
Here is how we explain it to folks at the counter.
Rotary Cutter: For Grass and Brush
A rotary cutter (most people call it a bush hog, though that is a brand name) is a PTO-driven cutter that spins heavy blades under a steel deck. It handles tall fescue, bahia grass, dog fennel, and light brush. It is not a lawn mower. The cut is rough, and that is fine, because the job is pasture maintenance, fence row cleanup, and clearing around food plots, not manicured turf.
We carry two in the LS tractor attachments lineup:
The MRC3060SC is a 60-inch regular-duty cutter with a slip-clutch driveline. Slip clutch matters. When the blade finds a buried stump or a chunk of fence wire, the clutch gives instead of snapping your PTO shaft. It has a 50 HP gearbox and handles brush up to 2 inches thick. The tractor range is 24 to 50 HP, which covers everything from the smallest sub-compact tractors up through the MT242HE. The deck weighs 718 pounds and cutting height adjusts from 2 to 10 inches.
The MRC5072SC is a 72-inch heavy-duty version with the same slip-clutch protection, but a 75 HP gearbox and a heavier stump jumper. It weighs 880 pounds and needs 35 to 72 HP to pull it properly. This is the cutter we hang behind the MT347HC and the MT4 utility tractors. If you have 20 or more acres of pasture that only gets cut twice a year, this is the one that does not bog down in August when everything is head high and thick.
The sizing decision is straightforward. Running a compact tractor on 5 to 15 acres with occasional brush, the MRC3060SC handles it. Step up to the MRC5072SC when you are on a bigger tractor and working heavy ground that grows back fast in the South Mississippi heat and humidity.
Box Blade: For Moving Dirt
A box blade is a three-sided steel box with cutting edges on the front and bottom. You use it to move dirt, level a pad, backfill a wash, or pull gravel back into a pothole. It does not cut anything growing. Pull it forward and it scrapes and carries. Lower the rear edge and back-drag to feather a surface or clean up around a barn.
Box blades are not a finishing tool, but they are the right tool for driveway work, food plot prep, and rough grading around a new building or well pad. We stock box blades in the LS attachments section. Call for current sizing and availability, as the right width depends on your tractor frame.
The honest caveat is this: a box blade takes some practice. Grading flat is not as simple as it looks, especially on a sloped driveway or in clay that has been packed for years. Give yourself a few hours on a section of driveway before you tackle anything that matters.
Land Grader: For Driveways and Shell Pads
The MLG3060 is a 60-inch land grader on a Cat 1 quick hitch. Where a box blade pushes and holds material in the box, a land grader is built to reshape surface grade over a wider swath in fewer passes. It runs on anything from 20 to 60 PTO horsepower, which means it works behind a sub-compact all the way up through the MT242HE.
It holds 14.72 cubic feet of material and weighs 436 pounds. For gravel driveways, shell pads around a shop, or a farm lane that washed out after a rain, this tool puts the surface back where it belongs without a lot of fuss. The Cat 1 quick hitch means you can swap it in and out without tools.
Who Should Not Buy a Rotary Cutter First
If your main need is a driveway or a bare dirt pad, a cutter sits in the barn while you wish you had a grader. Same goes the other way: if you have an overgrown pasture and a cutter is the obvious first buy, a land grader waits.
Some people buy both early and that is fine. Most of the time the sequence is: get the tractor, get the cutter, and add the grader or box blade when the driveway project comes up.
Matching the Implement to Your Tractor
The size of the implement should match the tractor pulling it. Running a 72-inch cutter behind a 24 HP sub-compact bogs the engine and wears things out faster than they should. The rule is to look at PTO horsepower, not engine HP, since that is what the implement actually sees.
If you are running an MT226E or MT125, the MRC3060SC is the right cutter. If you are on an MT232HE or MT242HE, either cutter works, but the 60-inch is plenty. The MT347HC and anything in the compact tractor or utility tractor class can pull the MRC5072SC without straining.
For grading, the MLG3060 works across the whole compact range without needing a bigger tractor frame underneath it.
