MechMaxx flail mowers: EFS, NAM, VAM, and KDK
MechMaxx sells PTO 3-point flails factory-direct across five series we spec-check: light-duty EFS, utility NAM hammers, NAM-H 16″ travel, grass-only VAM ditch-bank heads, and Cat 2 KDK. On these lines the model number is the cutting width.
By Tom Brennan · Editor
Our catalog covers 12 models from 48″ to 72″, list/sale $1,499 to $3,699. Expect aggressive pricing and a published 1 year machine warranty. That is the support tradeoff versus Woodmaxx’s 2 years parts coverage. MechMaxx’s public store also lists ATV decks and heavier VBM/AGF verge mowers we have not spec-checked.

How to pick a MechMaxx flail series
EFS
Light-duty value decks for compact tractors
EFS48 and EFS60 — light-grass decks with 0.8 lb hammers and a published ~0.75″ material limit. 15–35 HP class. EFS60’s 15 HP floor is 3.0 HP/ft, the catalog edge.
In catalog: EFS48, EFS60
NAM
Heavier hammers and wider cuts
NAM60/68 for 30–60 HP; NAM72 for 45–85 HP. 1.8 lb hammers and a 5″ rotor — width-per-dollar against Woodmaxx FM decks, not a 30 HP 72″ mower.
In catalog: NAM60, NAM68, NAM72
NAM-H
NAM cutting package with hydraulic offset
NAM68H (30–60 HP) and NAM72H (45–85 HP) add 8″ left or right of slider travel (16″ total). That is not Woodmaxx cut-edge-from-PTO reach, and it is not ditch-bank tilt.
In catalog: NAM68H, NAM72H
VAM
Articulating heads for tender-grass banks
VAM48/60/65 keep the tractor on level ground with hydraulic swing and tilt. MechMaxx limits the line to green or tender grass — not tall grass, shrubs, vines, or brambles. Two rear remote pairs. Offsets 69/77/85″.
In catalog: VAM48, VAM60, VAM65
KDK
Cat 2 decks for tougher roadside work
KDK63H and KDK72H — Cat 2, 6″ rotor, 2.7 lb hammers (fewer of them: 37.8 / 43.2 lb total vs NAM’s 50.4), ~13″ extend, 50–75 HP. Heavier frame, not more rotor steel than NAM72H.
In catalog: KDK63H, KDK72H
EFS (EFS48, EFS60): lightest and cheapest for 15–35 HP open grass. 0.8 lb hammers and a published ~0.75″ material limit. EFS60’s 15 HP floor is 3.0 HP/ft, the catalog edge. Not a cheap Woodmaxx FM-54 with extra width.
NAM (NAM60, NAM68, NAM72): fixed 1.8 lb hammers and a 5″ rotor. NAM60/68 are 30–60 HP. NAM72 is 45–85 HP. Do not treat Woodmaxx’s 30 HP FM-78 floor as a NAM72 floor.
NAM-H (NAM68H, NAM72H): the NAM cutting package plus 8″ left or right of slider travel (16″ total), one remote. Not Woodmaxx cut-edge-from-PTO reach, and not ditch-bank tilt.
VAM (VAM48, VAM60, VAM65): articulated heads so the tractor stays on level ground. MechMaxx limits the line to green or tender grass. Two rear remote pairs. Ditch-bank buying guide →
KDK (KDK63H, KDK72H): the only MechMaxx Cat 2 decks in this catalog. Heavier individual hammers (2.7 lb) and a heavier frame. Total hammer mass is still below NAM72H. About 13″ of extend, 50–75 HP.

Support
MechMaxx flail mower warranty
MechMaxx publishes a 1-year warranty on machines (separate engine warranties may apply on some powered products). 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. Source: MechMaxx about page.
Factory-direct pricing is the pitch. Local dealer parts counters are not. Confirm freight, remote count (VAM needs two pairs), and the current machine warranty on the listing before you order. If a 2-year parts process is the reason you sleep at night, the FM series is the other door.

MechMaxx vs Woodmaxx flail mowers
MechMaxx wins on sticker and on jobs Woodmaxx does not sell: VAM ditch-bank tilt, a 60″ light-duty cut under $1,700, and Cat 2 KDK side-shift without FM-96H money. Woodmaxx wins on published parts warranty, Y-blade choice, and denser mid-size FM build notes (NSK, Gates BX39, Q235).
MechMaxx flail mower FAQ
What MechMaxx flail mowers are available?+
MechMaxx’s store lists dozens of flail SKUs, including color variants, ATV decks, and heavier VBM/AGF verge mowers. Our catalog spec-checks 12 PTO 3-point models across five series: EFS (light grass), NAM (utility hammers), NAM-H (16″ slider travel), VAM (grass-only ditch-bank), and KDK (Cat 2 side-shift). Widths in that set run 48″ to 72″.
Does the MechMaxx model number equal cutting width?+
Yes on the PTO 3-point lines we cover. EFS48 cuts 48″, NAM72 cuts 72″, VAM65 cuts 65″. That is the opposite of Woodmaxx FM naming, where FM-54 cuts 47″. Size MechMaxx to the model number and the published PTO band.
Do MechMaxx flail mowers have Y-blades?+
Not in the EFS, NAM, NAM-H, VAM, or KDK SKUs in our catalog. Those rotors publish hammer packages. If you want hammer or Y-blade choice at order, look at Woodmaxx FM.
What warranty do MechMaxx flail mowers include?+
MechMaxx publishes a 1-year warranty on machines (separate engine warranties may apply on some powered products). 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. Against Woodmaxx FM (2-year parts), the shorter term is the main support tradeoff for MechMaxx’s lower stickers.
Which MechMaxx series is a ditch-bank mower?+
VAM. Articulating heads with hydraulic swing and tilt so the tractor can stay on level ground. MechMaxx limits VAM to green or tender grass, not tall grass, shrubs, vines, or brambles. Two rear remote pairs. NAM-H and KDK shift laterally; they do not tilt.
How is NAM-H side shift different from Woodmaxx H?+
NAM68H and NAM72H add 8″ left or right of slider travel (16″ total) on the NAM cutting package. Woodmaxx H models publish cut-edge reach from PTO center, which is a different geometry. Neither is ditch-bank tilt.
MechMaxx or Woodmaxx: which flail should I buy?+
Buy MechMaxx when purchase price and lineup breadth come first, and a published 1 year machine warranty is acceptable. Buy Woodmaxx when 2 years parts coverage and hammer/Y-blade choice on a single FM series matter more.
