Kubota LX3520 · FLAIL MOWERS

Flail mowers for the Kubota LX3520

The LX3520HSD sits between two WoodMaxx mower boundaries: 28.7 PTO hp exceeds FM-54 Y-blade’s 25 hp maximum but is below FM-78 hammer’s 30 hp minimum. FM-62 hammer’s 55-inch cut falls in the middle, with fixed and hydraulic-offset versions that require different equipment and load checks.

THE DECISION IN NUMBERS

LX3520HSD: a middle mower range between two exclusions

Blade configurations are explicit. Numerical power inclusion does not verify mowing performance, actual cutting-edge reach or complete operating weight.

Scroll the table sideways on smaller screens.

Sources for this decision table (13)

Smaller and larger are not substitutes for checking the power band

The FM-54 Y-blade mower has an upper limit that the LX3520HSD exceeds. The larger FM-78 hammer mower has a minimum that it does not reach. FM-62 hammer’s 24–45 PTO-hp band includes 28.7, but that only creates a candidate for a job-specific review. Do not round 28.7 to 30 or borrow the narrow DTN tractor’s separate PTO rating.

A 55-inch swath needs an actual tire measurement

Kubota lists 53.7 inches overall width at minimum tread with R1 tires. FM-62’s published cut is 55 inches, only 1.3 inches wider in total than that nominal tractor width. That is not a verified coverage allowance: tire selection, tread, fixed placement and actual cutting-edge position matter. Obtain a dimensioned layout before expecting both tracks to be cut.

The rear-outlet label does not establish a side-shift circuit

Kubota’s table says rear outlet and 9.5 gpm total pump output; it does not establish installed rear valve count or usable delivery for the mower. Fixed FM-62 needs no rear connection for offset adjustment. FM-62H does, and the mower’s required flow/pressure remain unverified. Confirm the complete valve, coupler and cylinder requirements before paying for hydraulic side shift.

Compare the two mower loads against the correct tractor reference

The current mower manual lists 774 lb for fixed FM-62 and 860 lb for FM-62H, an 86 lb difference on that product-weight basis. Operating inclusions and conflicting page weights still need resolution. Use the tractor’s 1,962 lb at-24-inch reference for the initial load-center inquiry, not the web field’s mislabeled 2,535 lb, and obtain implement/ballast approval for the actual geometry.

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. Its 34.9 engine hp is inside, but its 28.7 PTO hp is 1.3 short of 30, so the answer depends on which figure Farmry means; ask before buying. Its published lift at 24 inches, 1,962 lb, carries that weight with 663 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 Kubota LX3520’s 28.7 PTO hp is inside all three. Its published lift at 24 inches, 1,962 lb, carries even the 390-lb EF125 with 1,572 lb to spare. Betstco listed them at $1,462, $1,547 and $1,632 on November 14, 2026, with the PTO shaft included.
