MechMaxx EFS60 review
The EFS60 is a cheap way to get 60″ of flail width, but the 15–35 HP rating should be read cautiously in dense material because a full-width rotor asks more from small tractors.
Pros and cons
Pros
- 60″ cut at a $1,699 sale price
- Only 406 lb machine weight for the width
- SKF external bearings, belt tensioner, and shear-bolt PTO in the published spec
Cons
- 15 HP is optimistic for dense brush across a 60″ rotor
- 1-year warranty and thinner support story than Woodmaxx
- Hammer-only rotor and light-duty material limit
01What the EFS60 actually is
MechMaxx lists the EFS60 as a 60″ cut, 65″ overall Category 1 light-duty flail for 15–35 HP tractors. Verified weights are 406 lb machine and 503 lb shipping, with a 0.6″–1.8″ cutting-height range.
The spec stack mirrors the EFS48 in larger form: a 3″ rotor at 2,958 RPM, 11″ blade swing, about 97 mph tip speed, three 13x1041 belts with a tensioner, SKF external bearings, and a shear-bolt PTO shaft.
02Horsepower reality
The lower end of the 15–35 HP rating is optimistic for dense brush or heavy grass across a 60″ rotor. Treat 15 HP as a light, slow, short-material scenario rather than a promise that a small subcompact can run full-width rough mowing quickly.
If your tractor is near the bottom of the range, the EFS48 or a narrower Woodmaxx may be the better fit. If your tractor is comfortably in the compact range and the work is open, the EFS60's width is the point.
03Value vs Woodmaxx and NAM models
Compared with Woodmaxx FM-62, the EFS60 buys more nominal cutting width for much less money, but gives up the Woodmaxx 2-year warranty, Y-blade option, and heavier support story. It is the value answer, not the premium answer.
Compared with MechMaxx NAM60, the EFS60 is lighter-duty and cheaper. Step up to NAM when heavier hammers and a stouter platform matter more than keeping the machine light and inexpensive.

Tractor compatibility
- Match PTO horsepower to 15–35 HP. Use PTO HP from the tractor manual, not engine HP. This 15 HP floor is 3.0 HP per foot of cut — the catalog edge. Treat it as light grass, not a 15 HP brush deck.
- Machine weight is about 406 lb (shipping ~503 lb) — confirm your tractor’s 3-point lift capacity with margin for the PTO shaft and terrain.
- Hitch requirement: Category 1.
- No rear remotes required for cutting. A standard 540 RPM PTO and matching hitch is enough.
- Ballast the front end on steep or soft ground, especially with wider decks (60″).
Who should buy the EFS60, and who should skip it
Compact owners cutting mostly open grass who prioritize width per dollar, have lift capacity for a 406 lb machine, and can slow down when the mower starts to load the tractor.
You want 60″ of cut on a tight budget
The verified $1,699 sale price is the main attraction.
Your mowing is mostly open grass
Open, maintained or semi-maintained areas suit the EFS60 better than dense brush lanes.
Your tractor has real compact-class margin
A machine near the upper half of the 15–35 HP band will have an easier time than a 15 HP edge case.
You expect heavy brush performance at 15 HP
The published rating is broad; dense material at full width needs more horsepower and patience.
You want hydraulic side shift
EFS60 is fixed/center mount only with zero rear remotes required.
You want Y-blades or a longer warranty
Woodmaxx costs more but offers hammer/Y-blade selection and a 2-year parts warranty.
Alternatives to consider
Accessories worth planning for
Front ballast / suitcase weightsOptional
Worth checking before lifting a 406 lb mower, especially on smaller tractors in the rated range.
Spare 13x1041 belt setOptional
The EFS60 uses three belts with a tensioner; a spare set helps avoid downtime.
Replacement hammer and hardware kitOptional
Wear parts for the 24-hammer rotor; inspect hardware after dense grass or debris contact.
Shear bolts and PTO toolsOptional
Keep correct shear bolts and tools for measuring/cutting the driveline if needed.
Hammers vs Y-blades
Cast-steel hammer blades
24 hammers · ~0.8 lb each
Best for: Open grass, weeds, and light-duty rough mowing
Finish: Mulched / utility finish
The 60″ width asks more from small tractors; hammers should be paced carefully in dense material.
Hammer-only published configuration. Choose a Woodmaxx model if an order-time Y-blade finish option is important.
What owners and shoppers say about the EFS60
Themes blended from Green Tractor Talk shopping threads about MechMaxx 60″ flails, brand-level owner comments on nearby EFS models, and manufacturer specs (retrieved 2026-08-07). Model-specific long-term reviews are still thin.
- Budget width alternative. Shoppers compare the EFS60 as a much lower-cost path to a 60″ flail versus dealer-brand decks.
- Remotes decide fixed vs hydraulic. Advice threads push buyers without rear remotes toward fixed EFS decks, and hydraulic models only after remotes are sorted.
- Optimistic lower HP band. The published low HP floor is treated cautiously for dense 60″ cutting; slower travel is the practical advice.
- Light-duty expectations. Published EFS positioning and owner comments cluster around grass and light brush, not heavy clearing.
- Spare belts and debris awareness. General flail advice in the same threads stresses carrying spare belts and watching for hidden debris.

FAQ
What tractor size fits the MechMaxx EFS60?+
MechMaxx lists the EFS60 for 15–35 HP Category 1 tractors. Treat the 15 HP lower end cautiously: dense grass or brush across a 60″ rotor will need slow travel and more PTO margin.
How wide is the EFS60?+
The verified cutting width is 60″ and overall width is 65″.
Does the EFS60 require rear remotes?+
No. EFS60 is a fixed/center-mount light-duty flail and requires zero rear hydraulic remotes.
What blades come on the EFS60?+
MechMaxx lists 24 cast-steel hammer blades at about 0.8 lb each. No Y-blade option is listed for this SKU.
Is 15 HP enough for the EFS60?+
Only for easy, light material at conservative ground speed. For dense brush or tall heavy grass, the lower end of the published range is optimistic.
What belts and rotor specs does the EFS60 use?+
Verified specs list a 3″ rotor at 2,958 RPM, about 97 mph tip speed, 11″ blade swing, and three 13x1041 belts with a tensioner.
EFS60 vs Woodmaxx FM-62, which should I buy?+
Buy EFS60 for width-per-dollar at a verified $1,699 sale price. Buy Woodmaxx FM-62 for a 2-year warranty, Y-blade option, heavier support positioning, and a more conservative compact-tractor match.
EFS60 vs EFS48, which is safer for a small tractor?+
EFS48 is the safer small-tractor fit because it is narrower and slightly lighter. EFS60 is for buyers who have enough PTO and lift margin to use the extra width.
What warranty does the EFS60 include?+
MechMaxx publishes a 1-year warranty on machines (separate engine warranties may apply on some powered products). Against Woodmaxx FM models (2-year parts), that shorter term is the main support tradeoff for MechMaxx's lower sticker. Confirm the current machine warranty and claim path on the MechMaxx site before you buy; coverage language is thinner than Woodmaxx's published parts process.
