Land Pride FM2584 hammer vs WoodMaxx FM-78 Y: an 84-inch mower on an unstated basis or 70 inches on a PTO range
FM2584 and FM-78 are among the few flails on this site that list Category 2. On a KIOTI NS6010, FM-78’s 30–65 PTO hp range is cleared by about 18 on either transmission. FM2584’s 49-hp minimum is 0.7–1.2 above the NS6010’s PTO figures and 8.7 below its engine rating, and Land Pride does not say which it means. FM2584 also cuts 14 inches wider and carries hammers; this FM-78 carries Y-blades.

The differences that matter.
01
An unstated basis against a PTO range
Land Pride lists FM2584 at 49–80 tractor hp without naming engine or PTO. WoodMaxx’s manual lists FM-78 at 30–65 PTO hp for Y-blades and hammers.
A tractor with 48 PTO and 58 engine hp is inside FM-78 on any reading and inside FM2584 only if Land Pride means engine power.
This FM2584 is configured with hammer rotor 333-137A. This FM-78 carries Y-blades; WoodMaxx says Y-blade and hammer mowers are not interchangeable and points Y-blades toward grass.
Choose by growth: hammers for brush and saplings, Y-blades for grass.
About 1,200 lb plus rotor against an unverified Y weight
Land Pride lists FM2584 at 1,236 lb with a duckfoot rotor and no complete hammer weight. WoodMaxx gives FM-78 880 lb in its manual and 710 lb plus a 39-lb shaft on its page, without a Y-specific operating weight.
FM2584 is the heavier rear load by roughly 350 lb or more; confirm both complete weights before planning ballast.

FM-78’s page hero and manual support Category 1 or 2 with bushings while lower page text says Category 1 only; the manual counts 22 Y-blade sets where the page counts 44 Y pieces.
