MechMaxx Flail Mowers: Which Size Fits Your Tractor?
As Amazon Associates, we earn from qualifying purchases. This means we may receive a small commission at no extra cost to you if you click through and make a purchase.
MechMaxx makes tractor attachments for small farms and rural property owners, and flail mowers are among its most popular tools. A flail mower uses many small hammers or blades hanging from a spinning drum (called the rotor) to chop grass, weeds and brush into fine pieces. Because the hammers swing back when they hit something hard, flail mowers handle rough ground and thick growth better than a regular lawn mower deck.
The six MechMaxx items below differ by size and job: two listings cover the 60 inch EFS60 rear mower for 15-35 HP tractors, the VAM48, VAM60 and VAM72 are offset ditch bank mowers for bigger tractors and slopes, and one is a set of replacement hammers for MechMaxx ATV flail mowers.
MechMaxx Flail Mowers Compared
| Model | Working Width | Recommended Tractor HP | Max Material Diameter | Style |
|---|---|---|---|---|
| 60” inch PTO Powered 3 Point (EFS60) | 60 inches | 15-35 HP | 0.75 inch | Rear mount, standard duty |
| MechMaxx 60″ PTO Drive Offset Flail (VAM60) | 60 inches | 25-60 HP | 1.5 inches | Offset ditch bank |
| 48″ Flail Mower by MechMaxx (VAM48) | 48 inches | 25-50 HP | 1.5 inches | Offset |

60” inch PTO Powered 3 Point EFS60 for Compact Tractors
Mech Maxx
60'' inch PTO Powered 3 Point Standard Duty Flail Mower for 15-35hp Tractor, NOT Suitable for Quick Hitch, Model EFS60
Price and specifications are read from the Amazon product page and can change.
60” inch PTO Powered 3 Point
Best for: Small tractors mowing open fields
Pros
- Fits 15-35 HP tractors
- 24 flail hammers
- Kickstand for storage
Cons
- Not for quick hitch
- Mulches only up to 0.75 in
The 60” inch PTO Powered 3 Point Standard Duty Flail Mower, model EFS60, is designed for 15-35 HP tractors. Two terms help here. The PTO, or power take-off, is the spinning shaft at the back of a tractor that powers attachments; this mower comes with its PTO drive shaft and runs at 540 RPM, the common standard speed. The 3-point hitch is the three-arm mounting system on the back of most tractors, and this one needs a Category 1 hitch, the size used on small tractors.
The mower has a 60 inch working width, 24 flail hammers, a belt drive, front safety chains to keep debris from flying forward, sealed tapered roller bearings and a kickstand for storage. It can mulch material up to 0.75 inch in diameter and cuts between 0.6 and 1.8 inches above the ground. It weighs 673 pounds. The listing clearly states it does not work with quick hitch units, a coupling system some owners add to their tractors.
This suits a new owner of a compact tractor who needs to keep a field, pasture or large yard short. It gives way to the offset VAM models when you need to reach ditches or cut thicker brush.
MechMaxx 60″ PTO Drive Offset Flail VAM60 for Ditches and Slopes
Mech Maxx
MechMaxx 60" PTO Drive Offset Flail Ditch Bank Mower, Model VAM60 Orange
Price and specifications are read from the Amazon product page and can change.
MechMaxx 60″ PTO Drive Offset Flail
Best for: Ditches and embankments on mid-size tractors
Pros
- Hydraulic tilt and side shift
- Mulches up to 1.5 in
- 77 in. lateral reach
Cons
- Needs 25-60 HP tractor
- Not for quick hitch
The MechMaxx 60″ PTO Drive Offset Flail Ditch Bank Mower, model VAM60, is built for sloped ground. “Offset” means the mower can sit to the side of the tractor instead of directly behind it, so you can drive on flat ground while the mower cuts a ditch or bank. This model uses hydraulics (your tractor’s fluid-powered controls) to tilt down 60 degrees, tilt up 90 degrees and move up to 77 inches to the side from the center.
It runs from an included PTO shaft at 540 rpm with a rotor speed of 2356 rpm, fits Category 1 3-point hitches and is recommended for 25-60 HP tractors and loaders. The working width is 60 inches, it mulches material up to 1.5 inches thick and cuts from 0.65 to 2 inches above the ground. It weighs 613 pounds, comes with a 1-year warranty and, like the EFS60, is not suitable for quick hitch units.
Choose this for orchards, vineyards, fence lines and drainage ditches on a mid-size tractor. If your tractor is under 25 HP, the EFS60 is the realistic choice.
48″ Flail Mower by MechMaxx VAM48 for Narrower Work

48" Flail Mower by MechMaxx

48″ Flail Mower by MechMaxx
Best for: Narrower paths with 25-50 HP tractors
Pros
- Offset design
- Handles 1.5 in. material
- Hydraulic hoses listed
Cons
- Listing has conflicting specs
- Few details on tilt range
The 48″ Flail Mower by MechMaxx, model VAM48, is a smaller offset mower for 25-50 HP tractors. It has a 48 inch working width, a 56 inch overall width, a rotor speed of 2356 rpm and belt drive. It handles material up to 1.5 inches in diameter.
The listing mentions a PTO drive shaft, a Category 1 3-point hitch, front safety chains, sealed roller bearings, storage brackets, G1/2 inch hydraulic fittings with four hydraulic hoses and a 1.375 inch Z6 spline end. It does not give the tilt range or lateral reach. The listing is also inconsistent: it names “Gas Powered” as the power source and green as the color, though the features describe a PTO-driven tractor mower, and it gives a ground clearance of 0.5-0.6 inch without further explanation. Confirm details with the seller before ordering.
This suits owners who want the offset style for tighter spaces or narrower trails. For more reach on slopes, the VAM60 lists full tilt and side-shift figures.
8-Piece Forged Steel Hammer Set for MechMaxx ATV Flail Mowers
Mech Maxx
8-Piece Forged Steel Hammer Set for ATV120/140 Flail Mowers by MechMaxx
Price and specifications are read from the Amazon product page and can change.
8-Piece Forged Steel Hammer
Best for: MechMaxx ATV120 and ATV140 owners
Pros
- Forged steel hammers
- Set of eight
Cons
- Fits only ATV120 and ATV140
- No other specs listed
The 8-Piece Forged Steel Hammer Set is a pack of eight replacement hammers. The listing says it fits the MechMaxx ATV120 and ATV140 flail mowers only, which are tow-behind ATV models rather than the tractor mowers in this guide.
The listing gives little else beyond forged steel construction and black finish. Flail hammers wear down over time, especially when they hit stones, so owners of those ATV mowers can use a set like this to restore a clean cut. If you own an EFS60 or VAM model, this set is not listed as compatible.
72-Inch Heavy Duty Offset Ditch Bank VAM72 for Large Properties
Best for: Large farms with 70-100 HP tractors
Pros
- 72 in. working width
- Italian CMR gearbox
- Mulches up to 3 in
Cons
- Needs large tractor
- Gearbox rating conflicts with HP range
The 72-Inch Heavy Duty Offset Ditch Bank Flail Mower, model VAM72, is the biggest mower in the lineup. It has a 72 inch working width, runs at 540 RPM and is designed for 70-100 HP tractors through a 3-point hitch and an included 1-3/8 Z6 PTO shaft.
It uses an Italian CMR gearbox and SKF shaft and rotor bearings, hydraulic rotation with a 55 degree downward and 90 degree upward tilt, and hydraulic side movement with a right-side offset. The description says it can mulch debris up to 3 inches wide in a single pass, with forged hammer flail blades, an adjustable rear roller for cut height and an adjustable rear access panel. There are two inconsistencies: the features mention 18 blades while the description calls them hammers, and the description rates the gearbox at 65HP even though the recommended tractor range is 70-100 HP. The listing also shows “Gas Powered,” which does not match a PTO-driven attachment.
This is for farms with large tractors, long ditches and thick overgrowth. Smaller tractors should stay with the VAM60 or VAM48.
60-Inch Light-Duty Flail Mower EFS60 Listing for Hobby Farms
Best for: Hobby farms on compact tractors
Pros
- Fits 15-35 HP tractors
- Sealed tapered roller bearings
- 1-year warranty
Cons
- Light duty rating
- Some listing specs look wrong
The 60-Inch Light-Duty Flail Mower is a second listing for the EFS60 model, here called light duty instead of standard duty. It is designed for 15-35 HP tractors with a 60 inch cutting width, an included PTO shaft and a belt drive.
This listing mentions front safety chains, sealed tapered roller bearings, storage brackets and a 1-year warranty. Unlike the first EFS60 listing, it describes an offset Category 1 3-point hitch. It does not give the hammer count, cutting height or maximum material size, and it lists “Gas Powered” as the power source, which is not correct for a PTO-driven mower.
It suits the same compact tractor owner as the first EFS60 listing. Compare both listings and ask the seller which hitch style you will receive. Once your field is under control, a walk-behind option such as a 21 inch battery lawn mower can handle the lawn near the house.
How to Choose the Right MechMaxx Flail Mower
Match horsepower first. The EFS60 fits 15-35 HP tractors, the VAM48 25-50 HP, the VAM60 25-60 HP and the VAM72 70-100 HP. A mower that asks for more power than your tractor has will struggle and wear quickly.
Check your hitch. All of these tractor mowers use a Category 1 3-point hitch and a 540 RPM PTO, and the EFS60 and VAM60 listings state they do not work with quick hitch units.
Think about terrain. For flat fields, a rear mower like the EFS60 is simple. For ditches, banks and fence lines, the offset VAM models tilt and shift sideways with hydraulics, so your tractor needs hydraulic outlets.
Consider what you are cutting. The EFS60 mulches up to 0.75 inch material, the VAM48 and VAM60 up to 1.5 inches, and the VAM72 up to 3 inches. Keeping any deck clean helps too; a non-stick mower deck spray reduces grass buildup on smaller mowers.
