New Holland Boomer 50 · FLAIL MOWERS

New Holland Boomer 50 flail mowers: FM2572 by half a horsepower on the gear tractor

Land Pride rates FM2572 at 42–80 hp without naming engine or PTO power. The gear Boomer 50’s 42.5 PTO hp clears it by 0.5; the HST’s 40.0 misses by 2.0; the 50 gross hp clears it by 8 on either. FM2584 (49) is inside only on engine power. WoodMaxx FM-78 and TMG TFMS50 are inside on both transmissions.

Sources for this decision table (18)

FM2572 by 0.5

On PTO power, the gear Boomer 50 clears FM2572’s 42-hp minimum by 0.5 and the HST misses by 2.0. On engine power both are 8 over. Land Pride’s manual calls the figure tractor horsepower and ties the minimum to speed, terrain and material. Ask Land Pride which figure it means before choosing FM2572 for the HST.

A side-shift alternative

TMG’s TFMS50 table gives 30–60 hp, and its manual says tractor power must not exceed 50 PTO hp. Both Boomer 50 figures are inside. TFMS50 cuts 49 inches with about 14 inches of hydraulic side shift, which uses the Boomer’s standard rear remote. The comparison below sets TFMS50 against FM2572.

Width on a 69.1-inch tractor

The Boomer 45–55 are 69.1 inches wide. FM2572 (72-inch cut) and FM-78 (70) span the tractor; FM2584 (84) does with room to spare. TFMS50 (49), FM-62 (55) and FH-EFGC155 (60) do not, though TFMS50’s side shift moves its cut toward the tire tracks.

Lift

Land Pride lists FM2572 at 1,040 lb with a duckfoot rotor and its hammer rotor separately; TMG lists TFMS50 at 660 lb operating weight; FM-78 is 880 lb in WoodMaxx’s manual. All are under 2,116 lb at 24 inches. Confirm complete operating weights.

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 50’s 42.5 / 40 PTO hp and 50 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. The New Holland Boomer 50’s 42.5 / 40 PTO hp is inside all three, 2.5 under the ceiling. 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.
