John Deere 4075R · FLAIL MOWERS
At 60 PTO hp, the 4075R is 5 under the 65-PTO-hp ceilings of WoodMaxx FM-78 and Farmer-Helper FH-EFGC155 and inside Land Pride’s 80-hp FM25 range. TMG’s TFM60 and TFMS50 manuals cap tractor power at 50 PTO hp, 10 under, and the 45-hp mowers are out.

WoodMaxx’s manual gives FM-78 30–65 PTO hp with hammers or Y-blades. The 4075R’s 60 is 5 under the ceiling, the closest any 4 Series model gets. The 4066R (57 brochure, 52 order book) has more room.
Land Pride rates the FM25 series at 33, 42 or 49 to 80 tractor hp without naming the basis. The 4075R is inside on both 60 PTO and 74.3 engine hp, so the basis does not decide here. FM2584 cuts 84 inches and lists Category I/II. The comparison below sets FM2584 against WoodMaxx FM-78.
TMG’s tables list TFM60 and TFMS50 at 30–60 hp without a basis, but their manuals say tractor power must not exceed 50 PTO hp. On that cap the 4075R is 10 over. Ask TMG which figure governs before buying one for a 60-PTO-hp tractor.
FM-78 is 880 lb in WoodMaxx’s manual; FM2584 is 1,236 lb with a duckfoot rotor and no complete hammer weight. Both are under 2,500 lb at 24 inches.
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 John Deere 4075R’s 60 PTO hp and 74.3 engine hp are both inside that range, so the basis does not change the result. Its published lift at 24 inches, 2,500 lb, carries that weight with 1,201 lb to spare; check front ballast all the same. Farmry rates the gearbox at only 50 hp, below this tractor’s 60 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.
