Kubota MX4900 · FLAIL MOWERS
Kubota’s TC860-1971-9 manual sets a 72-inch, 1,100-lb maximum for flail mowers on the MX4900. That removes Land Pride’s 84-inch FM2584 regardless of power and leaves the 72-inch FM2572 exactly at the width limit. WoodMaxx’s 70-inch FM-78 family and Farmer-Helper’s 60-inch FH-EFGC155 are inside both manual limits and their PTO ranges.

| Land Pride FM2572 (hammer) | 72 in. / 1,040 lb (duckfoot unit) + hammer rotor listed separately | At the width limit; complete hammer weight unconfirmed | 42–80 hp, basis unspecified: 0.7 short on PTO; inside on engine |

TC860-1971-9 printed p31 lists flail mowers at a 1,830-mm (72-inch) maximum cutting width and 500 kg (1,100 lb) maximum weight for the MX4900, MX5400 and MX6000. Rotary cutters have a separate 84-inch, 1,000-lb row. FM2584’s 84-inch cut exceeds the flail limit before any horsepower question arises. FM2572’s 72-inch cut equals it. Confirm that the manual supplied with the tractor carries the same table.
Land Pride lists FM2572’s standard unit at 1,040 lb with a duckfoot rotor, 60 lb under the manual’s 1,100 lb, and lists the 20-hammer rotor assembly separately at 261 lb. No complete hammer-configuration weight is published, so whether the hammer mower is inside 1,100 lb is unconfirmed. Its 42–80 hp range is also unstated: 41.3 PTO hp is 0.7 short, while every engine figure is inside.
WoodMaxx’s manual lists FM-78 at 880 lb and FM-78H at 968 lb, both 70-inch, rated 30–65 PTO hp; the MX4900 is 11.3 above the minimum. Betstco’s FH-EFGC155 page lists 25–65 PTO hp, a 60-inch cut and 741 lb (720 in the manual). Its 60-inch cut is narrower than the MX4900’s 69.7-inch minimum width. The comparison below sets FH-EFGC155 against FM-78.
Farmry LFS (15–35 hp) is exceeded on every figure. LFP47 (25–45 hp) is 3.7 inside on PTO power and over on every engine figure, so its basis decides. FM-62 (24–45 PTO hp) is 3.7 under its ceiling, but its 55-inch cut is much narrower than the tractor.
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 Kubota MX4900’s 41.3 PTO hp is inside all three. Its published lift at 24 inches, 2,310 lb, carries even the 390-lb EF125 with 1,920 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.
