WORKMASTER 40 flail mowers: FM-78 hinges on the HST rating

WoodMaxx rates its FM-78 family from 30 PTO hp, and the New Holland WORKMASTER 40 clears that on every figure except the HST operator manual’s 29.0. FM-62, Farmer-Helper, Farmry LFS and LFP47, TMG and Land Pride FM2560 fit.

FM-62 or FM-78

WoodMaxx FM-62 (55-inch) runs 24–45 PTO hp with hammers; FM-78 (70-inch) runs 30–65. FM-62 fits the WORKMASTER 40 on every figure; FM-78 needs the brochure rating or the gear manual figure. The comparison below sets them side by side.

Three PTO figures

New Holland’s workbook and March 2025 brochure give 34.0 PTO hp (gear) and 32.0 (HST); its November 2023 operator manual lists 30.8 and 29.0 observed PTO hp. At 29.0 the HST tractor is 1.0 short of the 30-hp minimums of FM-78 and Farmry’s HFS87, the only ratings that change a flail result here. The site screens the brochure figures.

Engine or PTO

Farmry rates LFS to 35 hp and Land Pride rates FM2560 from 33 hp, neither naming the basis. The WORKMASTER 40’s 40 engine hp is over LFS and inside FM2560; its PTO figures are the reverse for LFS and straddle FM2560’s 33.

Lift

New Holland’s workbook and brochure lists 1,433 lb 24 inches behind the lift point. Compare it with the attachment’s complete weight including the PTO shaft; WoodMaxx FM-78H, the heaviest attachment here, is 968 lb.

Farmry HFS87: 87-inch cut, Category I and II

Farmry rates the HFS87 at 30–85 hp without saying whether that is PTO or engine power, lists Category I and II, cuts 87 inches and weighs 1,299 lb with the shaft. The New Holland WORKMASTER 40’s 34 / 32 PTO hp and 40 engine hp are both inside that range, though the manual’s HST figure, 29.0 PTO hp, is 1 hp short of it, so ask Farmry which power it means for the HST. Its published lift at 24 inches, 1,433 lb, is only 134 lb more than the mower’s weight, so weigh the complete mower and check ballast first. Its gearbox rating, 50 hp, is not below this tractor’s PTO power. The 87-inch cut is 3 inches wider than Land Pride’s FM2584. Farmry’s page listed it at $4,499 on November 14, 2026.

Farmer-Helper FH-EF standard-duty mowers

Farmer-Helper rates its standard-duty FH-EF mowers by PTO power, all to 45 PTO hp with a 45-hp gearbox: the EF95 (37-inch cut) from 15, the EF105 (41-inch) from 16 and the EF125 (48-inch) from 20. They carry Y-blades for grass and light brush. The New Holland WORKMASTER 40’s 34 / 32 PTO hp is inside all three. Its published lift at 24 inches, 1,433 lb, carries even the 390-lb EF125 with 1,043 lb to spare. Betstco listed them at $1,462, $1,547 and $1,632 on November 14, 2026, with the PTO shaft included.
