Mahindra 1640 · FLAIL MOWERS

Mahindra 1640 flail mowers: 0.1 hp short of the 30-hp class

The 1640 Shuttle’s 29.9 PTO hp falls 0.1 hp short of the 30-PTO-hp minimum on WoodMaxx’s FM-78 family, and the HST is 2.3 short. Below that line the shortlist is broad: the 55–60-inch hammer class starts at 24–25 hp, and both transmissions exceed FM-54 Y’s 25-hp maximum. Mowers that do not say engine or PTO are where the 1640’s answer changes.

Flail screens on PTO and engine horsepower

Tractor reference: 1640 HST 27.7 PTO hp, Shuttle 29.9 PTO hp, 38.7 engine hp (standard unnamed); overall width 62 in. with ag tires, rear track unpublished. No Mahindra manual flail limit was located. Ranges and weights are the retained manufacturer figures.

29.9 is below 30

WoodMaxx’s current manual lists 30–65 PTO hp for FM-78 with either blade set, and the same range applies to FM-78H. Mahindra prints 29.9 for the 1640 Shuttle in both the brochure and the specification table, and a series paragraph rounds the family to “19-30 PTO hp”. The configuration figure, not the rounded series range, is the one to screen. At 0.1 hp short, the mower is outside its published range unless WoodMaxx confirms otherwise in writing.

Where the basis decides

Farmry LFS61 (15–35), TMG TFM60 and TFMS50 (30–60) and Land Pride FM2560 (33–80) do not state whether they mean engine or PTO power. With 38.7 engine hp and 27.7 or 29.9 PTO hp, the 1640 is above LFS61’s range on engine power and below the TMG and Land Pride minimums on PTO power. Each answer reverses with the basis, so ask the maker which figure it means before treating either outcome as settled.

The 55–60-inch hammer class fits

FM-62 hammer and FM-62H start at 24 PTO hp, leaving 3.7 or 5.9 hp. FH-EFGC155 lists 25–65 PTO hp on its current page; its Revision 12-12-17 manual uses engine horsepower for hydro tractors, under which the HST’s 38.7 also clears. LFP47’s 25–45 band includes both the PTO and engine figures. These are inside their ranges on any reading; compare cut width, blade type and weight next.

Width against a 62-inch tractor

Mahindra lists the 1640’s overall width as 62 inches with ag tires and does not publish rear track. A 60-inch EFGC155 or FM2560, or a 55-inch FM-62, may or may not cover the wheel path depending on offset and actual track. Measure the tractor and confirm the mower’s mounting positions before treating cutting width as coverage.

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. Its 38.7 engine hp is inside, but the 29.9 / 27.7 PTO hp are 0.1 / 2.3 short of 30, so the answer depends on which figure Farmry means; ask before buying. Its published lift at 24 inches, 1,720 lb, carries that weight with 421 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 Mahindra 1640’s 27.7 / 29.9 PTO hp is inside all three. Its published lift at 24 inches, 1,720 lb, carries even the 390-lb EF125 with 1,330 lb to spare. Betstco listed them at $1,462, $1,547 and $1,632 on November 14, 2026, with the PTO shaft included.
