FM2584 or FM-62

Land Pride FM2584 (84-inch) is rated from 49 hp without a basis, so the 4052R fits it only on engine power. WoodMaxx FM-62 (55-inch) runs 24–45 PTO hp, which the 4052R is inside on either PTO figure. The comparison below sets them side by side.

Engine or PTO

Land Pride does not say whether its 42- and 49-hp minimums mean engine or PTO power. The 4052R’s 51.5 engine hp clears both; its 41.2 PTO hp clears neither. The site keeps FM2572 and FM2584 pending Land Pride’s answer.

Lift and hitch

Deere’s 4 Series brochure lists the 4R with a Category 1 hitch and 2,500 lb 24 inches behind the link arms (3,130 lb at the ends). The heaviest attachment here, WoodMaxx FM-78H at 968 lb, is well under it; check the quoted weight with the shaft and the front ballast the dealer recommends.

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 John Deere 4052R’s 41.2 PTO hp and 51.5 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. 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 John Deere 4052R’s 41.2 PTO hp is inside all three. Its published lift at 24 inches, 2,500 lb, carries even the 390-lb EF125 with 2,110 lb to spare. This tractor has the power for heavier mowers; the FH-EF line suits grass and light growth, not thick brush. Betstco listed them at $1,462, $1,547 and $1,632 on November 14, 2026, with the PTO shaft included.
