WoodMaxx FM-62H vs FH-EFGC155: hydraulic shift or a wider fixed cut
FM-62H’s hammer configuration has a 55-inch cut and hydraulic side shift. The base FH-EFGC155 hammer mower cuts 60 inches and uses fixed mounting positions; its hydraulic kit is an additional configuration. Choose first whether moving the mower laterally from the tractor is necessary, then check the exact power range and load.

The differences that matter.
01
Installed hydraulic shift versus two fixed mounting positions
FM-62H includes hydraulic side shift and requires tractor rear remotes. Its manual lists left-shift extents of 36 inches left and 29 right from center, and right-shift extents of 22.5 left and 43 right. FH-EFGC155’s standard manual lists two fixed mounting positions, with 35.25 or 39.5 inches right of center; its hydraulic kit is not part of this base record.
FM-62H is the relevant choice when changing lateral placement during the job matters and the tractor has a suitable circuit. FH-EFGC155 may suit a consistent offset. These dimension labels do not establish cutting-edge reach, tire coverage or clearances; ask for a mounting drawing.
Five more inches of cut, with different hammer counts
FM-62H cuts 55 inches and lists 18 individual hammers. FH-EFGC155 cuts 60 inches and lists 24 hammers. FH-EFGC155’s page claims up to 3-inch wooded material, while WoodMaxx describes its hammer use for saplings of 1 inch or less; those are manufacturer claims with different conditions, not a comparative test.
Choose width around the actual mowing lane and tractor track, then describe the vegetation to the seller. A wider cut and more hammers do not establish more output at the same PTO power, and the two material-size claims should not be treated as equivalent performance ratings.
FM-62H’s manual specifies 24–45 PTO hp for hammers; the 20–45 PTO-hp row belongs to Y-blades. FH-EFGC155’s current page specifies 25–65 PTO hp, but the linked manual’s 25-hp minimum uses PTO power for gear tractors and engine power for hydrostatic tractors, and another manual paragraph permits up to 80 PTO hp.
The current-page EFGC155 band can inform a published screen, but it does not settle the conflicting manual revisions or bases. A tractor above 45 PTO hp raises a clear WoodMaxx hammer-limit question; do not silently apply its Y-blade minimum or expand either range.
FM-62H’s specification table gives a cutting-height range of 3/4 to 3-3/4 inches. FH-EFGC155’s page gives 0 to 6 inches.
For a job that calls for taller retained stubble, ask whether EFGC155’s adjustment can achieve the intended height on the terrain. For either machine, the minimum setting is not assurance of ground clearance on uneven land; review roller and skid setup before treating it as a finish-height guarantee.
Slip-clutch shaft versus the stated shear-bolt package
FM-62H’s page lists an included slip-clutch PTO shaft and the manual specifies Category 1 only for this size. FH-EFGC155 lists Category 1 and a Series 5 shear-bolt shaft in its main specifications; a separate page section instead says Series 4 and two belts, versus Series 5 and three belts in its main specifications/manual.
The package changes the protection parts and maintenance routine to quote. Have the seller identify the exact shaft, protection device and belts on the delivered mower. Broad Category 1/2 marketing on the WoodMaxx page does not override the FM-62H table’s Category 1 limitation.
FM-62H’s manual lists 860 lb product weight, but its page lists 716 lb mower-only plus a 39 lb shaft and also uses 860 lb as shipping weight. FH-EFGC155’s page lists 741 lb product and 789 lb crated, versus 720 lb product and 755 lb crated in its manual. Neither establishes the exact complete operating load for the selected hammer configuration.
Obtain written assembled weights with the shaft, hammers and all installed equipment before checking lift capacity and ballast. These inconsistent labels do not support a reliable claim that one complete mower is a specific number of pounds lighter.
Consider FM-62H when hydraulic placement solves the job
Shortlist the hammer FM-62H when a 55-inch swath is sufficient and changing lateral position matters. Verify the tractor’s rear circuit, couplers and the 24–45 PTO-hp hammer range, then resolve the conflicting load figures and supplied shaft setup.
Shortlist the base EFGC155 when its 60-inch cut, fixed mounting positions and stated height adjustment suit the mowing pattern. Keep the optional hydraulic kit outside the quote unless deliberately added, and resolve the page/manual power and package disagreements first.
FM-62H’s generic page range starts at 20 hp, but the current manual requires 24–45 PTO hp for hammers; 20–45 belongs to Y-blades. FH-EFGC155’s current page, transmission-specific manual footnote and 80-PTO-hp paragraph do not describe an identical power screen. Its Additional Information also pairs a 65-hp gearbox with a generic 50-hp tractor statement, which does not resolve the requirement.
FM-62H’s page describes a 14-inch shift, while the manual presents separate left/right extents. Their reference points do not establish cutting-edge travel. The manual identifies rear remotes and 1/2–14 NPTF hose ends, but the reviewed sources do not establish required flow, pressure or valve type. EFGC155’s manual also has handle-adjustment wording alongside its two-position specification.
FM-62H’s introductory Category 1/2 wording conflicts with its detailed Category 1 specification and manual. EFGC155’s main shaft/belt specifications conflict with Additional Information. The base EFGC155 record does not include the separately offered hydraulic kit.
The weight bases conflict for both mowers: FM-62H’s 860 lb is product weight in the manual but shipping weight on the page, which separately gives 716 lb mower-only and a 39 lb shaft. EFGC155 page/manual product and crate figures also differ. Complete hammer-specific operating loads remain unresolved.
