MechMaxx NAM68H review
The NAM68H is the MechMaxx value side-shift pick: 68″ cut, 16″ total hydraulic travel, and a lower price than Woodmaxx H models, balanced by a 1-year warranty and hammer-only rotor.
Pros and cons
Pros
- 8″ left/right hydraulic shift (16″ total)
- 28 heavy 1.8 lb hammers on the NAM cutting package
- Lower sale price than Woodmaxx FM-62H/FM-78H alternatives
Cons
- Needs one rear remote
- Not a true ditch-bank tilt mower. That is the VAM series
- 1-year warranty and hammer-only rotor
01What the NAM68H actually is
NAM68H uses a 68″ cutting width and 74″ overall width with a Category 1 hitch. Verified weights are 732 lb machine and 820 lb shipping, and the tractor range is 30–60 HP.
The H suffix means hydraulic lateral shift: MechMaxx lists 8″ left or 8″ right, for 16″ total travel. It requires one rear remote pair. It is not a ditch-bank or tilt mower; the deck stays in the side-shift category.
02Cutting package and manufacturer claim
The NAM68H spec includes 28 hammers at about 1.8 lb each, a 5″ rotor, 14″ swing, 4″ rear roller, four 17x991 belts, SKF external bearings, and a T6-LF-39 shear-bolt PTO shaft.
MechMaxx overview copy claims material capacity up to about 3″ diameter. We are treating that as a manufacturer claim, not a hands-on test result, and would still pace heavy material carefully.
03Value vs Woodmaxx FM-62H and FM-78H
Against Woodmaxx FM-62H, NAM68H offers more cutting width and a lower sale price, but gives up the 2-year warranty, Y-blade ordering option, and Woodmaxx support positioning. Against FM-78H, NAM68H is smaller and cheaper but cannot match the 70″ Woodmaxx deck's premium support story.
The clean buying case is budget side shift: if one rear remote and a hammer-only deck suit the property, NAM68H is compelling. If parts guidance, blade choice, and warranty term are top concerns, Woodmaxx is the safer comparison point.

Tractor compatibility
- Match PTO horsepower to 30–60 HP. Use PTO HP from the tractor manual, not engine HP. Published mins in this catalog are all at least 3.0 HP per foot of cut.
- Machine weight is about 732 lb (shipping ~820 lb) — confirm your tractor’s 3-point lift capacity with margin for the PTO shaft and terrain.
- Hitch requirement: Category 1.
- Budget one rear remote for lateral side shift. This deck does not tilt down a bank — slope work is the VAM line.
- Ballast the front end on steep or soft ground, especially with wider decks (68″).
Who should buy the NAM68H, and who should skip it
30–60 HP owners who need moderate hydraulic side shift for fences, orchards, and pond edges but do not need full ditch-bank tilt.
You need side shift, not ditch-bank tilt
The 8″ left/right hydraulic travel helps at fences and trees without the complexity of a VAM head.
Your tractor has one rear remote
One rear remote pair is required for the side-shift cylinder.
You want a lower-cost Woodmaxx H alternative
The value case is width and hydraulic shift for less upfront money.
You need to mow embankments below the tractor
NAM68H shifts sideways but does not articulate up/down like the VAM series.
You have no rear hydraulic remotes
Without a rear remote pair, the H feature cannot operate as intended.
You want the Woodmaxx warranty/support package
MechMaxx lists a 1-year warranty and direct-manufacturer path; Woodmaxx has a 2-year parts warranty.
Alternatives to consider
Accessories worth planning for
Rear remote hydraulic kitOptional
Required if your tractor lacks one rear remote pair for the side-shift cylinder.
Hydraulic coupler adaptersOptional
Confirm tractor-side couplers and hose routing before delivery; published specs require one remote pair.
Spare 17x991 belt setOptional
The NAM68H uses four 17x991 belts with a tensioner.
Front ballast / loader ballastOptional
Evaluate ballast before transporting a 732 lb hydraulic side-shift deck.
Hammers vs Y-blades
Heavy hammer blades
28 hammers · ~1.8 lb each
Best for: Side-shift rough mowing, fences, tree lines, and field edges
Finish: Mulched / utility finish
MechMaxx claims material up to about 3″ diameter in overview copy; treat that as a manufacturer claim and pace heavy work carefully.
Hammer-only published configuration. The hydraulic shift changes reach, not blade style.
What owners and shoppers say about the NAM68H
Written NAM68H forum volume is still thin. Themes blend manufacturer specs with Green Tractor Talk shopping threads and a public 1-year YouTube review (The Roy Boys, Massey Ferguson 1840M, uploaded 2025-08-24). Retrieved 2026-08-14. Not a scientific sample.
- Affordable hydraulic side shift. Shoppers looking at MechMaxx H decks usually cite lower cost per inch of hydraulic travel versus Woodmaxx H models. A public 1-year YouTube review exists for NAM68H on an MF 1840M.
- One-remote requirement. Side-shift use needs a rear remote pair. Green Tractor Talk shoppers who only have loader hydraulics often bounce off NAM68H until they add a rear valve.
- Material claims need caution. Manufacturer overview claims around thicker material capacity (about 3″) are treated as positioning, not proven field data.
- Not a ditch-bank head. Forum buyers comparing NAM-H to VAM keep mixing 16″ slider travel with tilt. NAM68H stays level. Banks that drop away from the tractor are the VAM job.
