Mahindra 1635 · FLAIL MOWERS
A 1635 has outgrown the 25-hp flails and not yet reached the 30-hp class. Its 26.0 or 27.6 PTO hp exceeds FM-54’s 25-hp maximum, falls short of FM-78’s 30-hp minimum, and lands inside the 55–60-inch hammer and Y options. Several mowers do not say whether they mean engine or PTO horsepower, and on this tractor that choice changes the answer.

|---|---|---|---|
| Farmry HFS87 | 30–85 hp, basis unspecified; Category I/II; 87-in. cut | 4 short / 2.4 short | Inside; ask Farmry which hp it means |
| Farmer-Helper FH-EF95 / EF105 / EF125 | 15 / 16 / 20–45 PTO hp; Category I; 37 / 41 / 48-in. cut | Inside | PTO-rated: engine hp not used |

| WoodMaxx FM-62 Y / FM-62 hammer / FM-62H | 20–45 (Y) or 24–45 (hammer) PTO hp; 55-in. cut | Inside; hammer margin 2.0 / 3.6 | PTO-rated: inside |
| Farmer-Helper FH-EFGC155 | 25–65 PTO hp; 60-in. cut | 1.0 / 2.6 above minimum | PTO-rated on current page |
| Farmry LFP47 | 25–45 hp, basis unspecified; 47.2-in. cut | Inside | 36.2 inside |
| Farmry LFS61 | 15–35 hp, basis unspecified | Inside | 36.2 exceeds 35 by 1.2: basis decides |
| TMG TFM60 | 30–60 hp, basis unspecified; manual 50 PTO hp max | Below 30 minimum | 36.2 clears 30: basis decides |
| Land Pride FM2560 | 33–80 tractor hp, basis unspecified | Below 33 minimum | 36.2 clears 33: basis decides |
| WoodMaxx FM-78 / FM-78 Y | 30–65 PTO hp | 4.0 / 2.4 below: excluded | PTO-rated: excluded |
WoodMaxx publishes 15–25 PTO hp for FM-54 with Y-blades. Both 1635 transmissions exceed the top of that range, by 1.0 hp on the HST and 2.6 on the Shuttle. A lighter mower is not automatically the conservative choice on a stronger tractor; the published maximum is a limit, not a suggestion. Choose a mower whose range includes the tractor.
Farmry’s LFS61 (15–35 hp), TMG’s TFM60 (30–60 hp) and Land Pride’s FM2560 (33–80 tractor hp) do not say whether they mean engine or PTO power. With 36.2 engine hp and 26–27.6 PTO hp, the 1635 is above LFS61’s range on engine power but inside it on PTO power, and the reverse holds for TFM60 and FM2560. The answer depends on the maker’s definition, so ask before buying.
FM-62 hammer and FM-62H start at 24 PTO hp, leaving 2.0 hp (HST) or 3.6 (Shuttle) of margin; the FM-62 Y configuration starts at 20. Betstco’s FH-EFGC155 starts at 25 PTO hp on its current page, clearing by 1.0 or 2.6. These are all inside their published ranges. Compare blade type, offset method and complete weight next.
Mahindra lists the 1635’s overall width as 64 inches but does not publish rear track in the reviewed table. A 60-inch EFGC155 or 55-inch FM-62 may or may not cover the wheel path depending on offset and actual track width. Measure the tractor and confirm the mower’s mounting positions before treating cutting width as coverage.
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 36.2 engine hp is inside, but the 27.6 / 26 PTO hp are 2.4 / 4 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 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 1635’s 26 / 27.6 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.
