Case IH Farmall 40A flail mowers: FM-78 fits; Farmry LFS depends on basis

WoodMaxx FM-78 (30–65 PTO hp), FM-62, Farmer-Helper FH-EFGC, TMG, Farmry LFP47 and Land Pride FM2560 fit the 40A on every Case IH figure. Farmry’s LFS mowers stop at 35 hp: the 40-hp engine is over, and so is the mechanical tractor’s 35.9 PTO hp on the 2026 sheet.

FM-78 on every figure

WoodMaxx’s manual gives FM-78 30–65 PTO hp. The lowest 40A figure, the page’s 32.0 for the HST, is still 2 over. The comparison below sets Farmry’s LFS61 against FM-78.

Farmry’s 35

Farmry rates LFS45, LFS53 and LFS61 at 15–35 hp without a basis. The 40-hp engine is over; the mechanical 40A’s 35.9 is over too, so the screen excludes it. The HST’s 34.8 is under on PTO power.

Land Pride FM2560

Land Pride rates FM2560 from 33 hp. Every 40A figure but the page’s HST 32.0 clears it on PTO power; the engine clears it either way.

Lift

FM-78H at 968 lb is the heaviest mower here, under the 1,596-lb lift at 24 inches.

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 Case IH Farmall 40A’s 35.9 / 34.8 PTO hp and 40 engine hp are both inside that range, so the basis does not change the result. Its published lift at 24 inches, 1,596 lb, is only 297 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 Case IH Farmall 40A’s 35.9 / 34.8 PTO hp is inside all three. Its published lift at 24 inches, 1,596 lb, carries even the 390-lb EF125 with 1,206 lb to spare. Betstco listed them at $1,462, $1,547 and $1,632 on November 14, 2026, with the PTO shaft included.
