| Mower | Published requirement | On 89 PTO / 105.6 engine hp | Result |
|---|---|---|---|
| Blue Diamond 403740 (87-inch) | 75–100 hp, basis unspecified; Category I and II | Inside on 89 PTO; 5.6 over on 105.6 engine | Ask Blue Diamond |
| Land Pride FM2572 / FM2584 | 42 / 49–80 hp, basis unspecified; Category 1 and 2 | 9 over on PTO; 25.6 over on engine | Excluded |
| WoodMaxx FM-78 / FM-78H / FM-78 Y | 30–65 PTO hp; Category 1 and 2 | 24 over | Excluded |
| Land Pride FM2560 | 33–80 hp; Category 1 | Over and hitch mismatch | Excluded |
| All other mowers here | To 65 hp or less | Over | Excluded |
Both Land Pride FM25 mowers list Category 1 and 2 and run to 80 hp. The M5-111 is over that on either reading, so neither is screened as a match. The comparison below shows how the two differ on smaller tractors.
A flail mower’s published maximum is its maker’s limit for the gearbox and driveline. This site does not screen past it. Of the flail mowers here, only Blue Diamond’s 403740 lists a range that reaches 89 PTO hp, and the M5-111’s engine is 5.6 over its 100.
Ask Blue Diamond whether its 75–100 hp means engine or PTO power. The 403740 cuts 87 inches, covering the 78.3- to 79.1-inch tractor, weighs 1,763 lb before the shaft, and needs a rear remote for its side shift.
Kubota’s 2026 catalog lists 4,630 lb 24 inches behind the lift point on the 8-speed M5 and 6,063 lb on the 12- and 24-speed tractors. Every attachment here weighs a fraction of either, so power and hitch decide the fit, not lift.
THE SCREEN, WITH ITS LIMITS VISIBLE
No pairing below is manufacturer-confirmed. “Preliminary” still requires implement limits, load center, ballast, hitch geometry and shaft checks.
Initial specification screen only. Scroll the table on small screens. Read the product page for every remaining check.
