Farmry LFS (15–35 hp), WoodMaxx FM-54 Y (15–25 PTO hp) and Farmer-Helper’s FH-EF95 and EF105 (15 and 16–45 PTO hp) are the only flails here that start below 20. The comparison below sets LFS53 against FM-54 Y.
WoodMaxx lists FM-62 with Y-blades from 20 PTO hp. The mechanical 25A is 0.8 short; a 25-class tractor rated 20 or more would reach it.
LFS53 cuts 53.1 inches and weighs 395 lb with its shaft; FM-54 cuts 47 inches at 408 lb. Both are far under the 1,433-lb lift.
The HST 25A’s 17.1 PTO hp is 2.1 over the 15-hp minimums. Mow tall or wet grass slowly.
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 25A’s 19.2 / 17.1 PTO hp is inside the EF95 / EF105 but short of the EF125’s 20-hp minimum. Its published lift at 24 inches, 1,433 lb, carries even the 347-lb EF105 with 1,086 lb to spare. Betstco listed them at $1,462 and $1,547 on November 14, 2026, with the PTO shaft included.
