KIOTI NX5510 · FLAIL MOWERS
WoodMaxx FM-62 stops at 45 PTO hp. The synchro NX5510’s 46.0 is 1.0 over that; the NX5510H’s 43.1 is 1.9 under. Farmry’s LFP47 (25–45 hp, basis unspecified) follows the same split on PTO power and is over on engine power. WoodMaxx FM-78, Land Pride FM2572 and TMG TFMS50 are inside on both transmissions.

THE DECISION IN NUMBERS
Tractor reference: KIOTI NX5510 and NX5510H; hitch Category 1 on the web page and in the manual, Category I & II in the brochure; 65.6–65.7 in. minimum width; 3,177 lb at 24 in. KIOTI’s manual has no flail row (rotary cutter 73 in., grooming mower 72 in.).

WoodMaxx’s manual gives FM-62 with hammers 24–45 PTO hp. KIOTI lists the synchro NX5510 at 46.0 PTO hp in its brochure, web page and manual, 1.0 over; the NX5510H, at 43.1, is 1.9 under. The documents agree, so the transmission decides it. The larger FM-78 (30–65 PTO hp) is inside on both.
Farmry lists LFP47 at 25–45 tractor hp without naming engine or PTO. The synchro NX5510 is over on both its figures. The NX5510H is inside on PTO power and 10 over on engine power, so Farmry’s basis decides. At 47.2 inches, LFP47 also cuts 18 inches narrower than the tractor; the comparison below sets it against the 70-inch FM-78.
The NX5510 is 65.6 inches wide (65.7 on the NX5510H web page). FM-78 (70-inch cut) and FM2572 (72) span it; FM-62 (55), FH-EFGC155 (60) and LFP47 (47.2) do not. TMG’s TFMS50 cuts 49 inches with about 14 inches of hydraulic side shift, which needs a tractor remote; the NX has one standard. KIOTI’s manual has no flail-mower width row, so ask KIOTI which limit applies.
KIOTI’s September 2025 brochure lists the NX5510 and NX6010 hitch as Category I & II, splitting from the NX4510 and NX5010 the same way the tire rows do. The current NX5510 web pages and the owner’s manual say Category 1. FM-78 fits Category 1 or 2 with bushings; FM2572 is Category I/II. Confirm the lower-link ends on the tractor before ordering.
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 KIOTI NX5510’s 46 / 43.1 PTO hp and 55 engine hp are both inside that range, so the basis does not change the result. Its published lift at 24 inches, 3,177 lb, carries that weight with 1,878 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 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. At 46 PTO hp the KIOTI NX5510 is 1 over their 45-hp ceiling, so they are out on that version; at 43.1 PTO hp the other version is inside all three. Its published lift at 24 inches, 3,177 lb, carries even the 390-lb EF125 with 2,787 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.
