FM2584 or FM-78

Land Pride FM2584 (84-inch) depends on whether its 49-hp minimum is engine or PTO power. WoodMaxx FM-78 (70-inch, 880 lb) fits on the PTO figure. The comparison below sets them side by side.

Category 2 first

Only four mower lines here list Category 2: WoodMaxx FM-78, Land Pride FM2572 and FM2584, Farmry HFS87 and Blue Diamond’s 403740, which needs 75 hp. The rest are Category 1 only, so the MT357’s hitch rules them out before power is checked.

Which PTO figure

LS’s July 2025 brochure prints the higher PTO figure under the gear columns; the current model page assigns it to the hydrostatic. This site follows the brochure and holds every result for review. Ask the dealer for the rating of the actual transmission.

Lift

LS’s September 2025 owner manual lists 2,469 lb 24 inches behind the lift point (2,755 lb at the link ends). The heaviest attachment here, WoodMaxx FM-78H at 968 lb, is well under it; ballast as the manual directs.

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 LS MT357’s 48.4 / 45.6 PTO hp and 57 engine hp are both inside that range, so the basis does not change the result. Its published lift at 24 inches, 2,469 lb, carries that weight with 1,170 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.

Compare each configuration.

No pairing below is manufacturer-confirmed. “Preliminary” still requires implement limits, load center, ballast, hitch geometry and shaft checks.
