New Holland Boomer 55 · FLAIL MOWERS

New Holland Boomer 55 flail mowers: the transmission decides FM-62

WoodMaxx FM-62 stops at 45 PTO hp. The gear Boomer 55’s 46.7 is 1.7 over; the HST’s 44.0 is 1.0 under. TMG’s TFMS50, whose manual stops at 50 PTO hp, is inside on both. Farmry LFP47 follows FM-62 on PTO power and is over on the 55 gross hp.

Sources for this decision table (18)

1.7 over, 1.0 under

WoodMaxx’s manual gives FM-62 with hammers 24–45 PTO hp. New Holland lists the Boomer 55 at 46.7 PTO hp on the gear transmission and 44.0 on the HST, on both its model table and specification table. The gear tractor is over; the HST is inside by 1.0, a margin to confirm with WoodMaxx.

TFMS50 has more room

TMG’s manual says tractor power must not exceed 50 PTO hp, and its table gives 30–60 hp without a basis. The Boomer 55 is 3.3 (gear) or 6.0 (HST) under the 50-PTO-hp ceiling and inside 30–60 on its 55 gross hp. TFMS50’s 49-inch cut and side shift suit fence and ditch work; the comparison below sets it against FM-62.

Larger mowers

WoodMaxx FM-78 (30–65 PTO hp, 70-inch cut) and Land Pride FM2572 (42–80 hp, 72-inch cut) are inside on both transmissions and both span the 69.1-inch tractor. FM2584 (49 hp) is 2.3 or 5.0 short on PTO power and 6 over on engine power; Land Pride does not say which it means.

LFP47 on the basis

Farmry lists LFP47 at 25–45 tractor hp. The gear Boomer 55 is over on both its figures. The HST is inside on PTO power (44.0) and 10 over on engine power (55), so Farmry’s basis decides. At 47.2 inches, LFP47 also cuts about 22 inches narrower than the tractor.

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 Boomer 55’s 46.7 / 44 PTO hp and 55 engine hp are both inside that range, so the basis does not change the result. Its published lift at 24 inches, 2,116 lb, carries that weight with 817 lb to spare; check front ballast all the same. 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. At 46.7 PTO hp the New Holland Boomer 55 is 1.7 over their 45-hp ceiling, so they are out on that version; at 44 PTO hp the other version is inside all three. Its published lift at 24 inches, 2,116 lb, carries even the 390-lb EF125 with 1,726 lb to spare. This tractor has the power for heavier mowers; the FH-EF line suits grass and light growth, not thick brush. Betstco listed them at $1,462, $1,547 and $1,632 on November 14, 2026, with the PTO shaft included.
