LS MT573 flail mowers: 3 hp under FM-78, Land Pride with room

At 62 PTO hp the MT573 is 3 under the 65-PTO-hp ceiling of WoodMaxx’s FM-78 mowers and inside Land Pride FM2572 and FM2584 (to 80 hp). TMG, the 45-hp mowers and every Category 1-only mower are out.

Width

LS lists the MT573 at 77.5 inches minimum overall width. FM2584’s 84-inch cut covers it; FM-78’s 70 and FM2572’s 72 do not, so they need an offset or overlap. The comparison below sets FM2584 against FM-78 Y.

Three under FM-78

WoodMaxx’s manual gives FM-78 30–65 PTO hp. The MT573C and MT573CPS list 62 PTO hp, 3 under. Ask WoodMaxx to confirm at that margin.

Category 1 attachments on this hitch

LS documents the hitch as Category 2 only (manual: CAT. 2, ISO 730:2014). Most attachments on this site list Category 1 only, so this site screens them as not matching. Some can be mounted with bushings or a Category 1/2 quick hitch; ask the dealer and the attachment maker before relying on that.

Remotes and lift

The MT573 has three rear remote pairs for a side-shift mower. FM-78H is 968 lb, far under the 4,718-lb lift.

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 MT573’s 62 PTO hp and 73 engine hp are both inside that range, so the basis does not change the result. Its published lift at 24 inches, 4,718 lb, carries that weight with 3,419 lb to spare; check front ballast all the same. Farmry rates the gearbox at only 50 hp, below this tractor’s 62 PTO hp; ask Farmry how hard it can be driven. 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.

THE SCREEN, WITH ITS LIMITS VISIBLE

Compare each configuration.

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