John Deere 3046R · FLAIL MOWERS
The 3046R’s disputed PTO figures do not change every mower decision. Both the U.S. book’s 34.1 and the linked brochure’s 36.6 clear FM78’s 30-PTO-hp minimum and exceed FM2560’s 33-hp minimum numerically. Width, fixed versus hydraulic offset, complete hammer-machine weight and installed rear valves become the useful next questions.

THE DECISION IN NUMBERS
34.1 and 36.6 are conflicting source values, not an adjustable power range. Clearing a stated minimum does not establish cutting performance or complete fit.
Scroll the table sideways on smaller screens.
| Mower / cutting width | Published power requirement | 34.1 book / 36.6 brochure | Next decision |
|---|---|---|---|
| FM2560 hammer · 60 inches | 33–80 tractor hp; basis unstated | Both PTO references exceed 33; current 45 engine label also exceeds it | Clarify the power basis, then exact hammer load and 8-inch fixed offset. |
| FM78 hammer · 70 inches | 30–65 PTO hp | 4.1 / 6.6 hp above minimum | 10 more cutting inches than FM2560; compare actual coverage and load. |
| FM78H hammer · 70 inches | 30–65 PTO hp plus hydraulic side shift | Same 4.1 / 6.6 hp margins | Verify installed rear SCV and circuit; an air-ride package is not proof of a retrofit. |
| FM2572 hammer · 72 inches | 42–80 tractor hp; basis unstated | Both PTO references below 42; 45 engine label above | Hold until Land Pride identifies engine versus PTO basis. |
| FM2584 hammer · 84 inches | 49–80 tractor hp; basis unstated | Both PTO references and 45 engine label below 49 | Outside the published minimum on either available basis. |
On the smaller 3039R, the FM2560’s unspecified 33-hp basis can decide the power screen. Here both documented 3046R PTO values and its engine label are above 33, although Land Pride still needs to define the requirement. That makes the 60-inch FM2560 a distinct comparison with the 70-inch FM78, rather than an automatic step to the widest model. FM2560 is 72 inches overall and has a fixed center or 8-inch right mounting position. Confirm actual cutting-edge coverage against the tractor’s measured rear-tire track; a nominal offset is not reach beyond a tire.
Deere’s order book links standard-seat open station 2000 to dual-mid SCV 3320 and less-mid-PTO 3400. Air-ride open station 2005 is linked to dual-mid plus one rear SCV 3330 and mid PTO 3420. A separate transmission note contradicts the standard-seat combination, and used machines may have been altered. For FM78H, request the build details and inspect the installed rear circuit. The fixed FM78 and FM2560 have no hydraulic side-shift cylinder. Tractor total pump flow cannot establish the H mower’s coupler, valve, pressure or return requirements.
The 3 Series brochure gives 2,200 lb at 24 inches behind the center link for this tractor. FM2560’s 965-lb manual reference is a duckfoot-equipped unit; the separate 222-lb hammer rotor cannot simply be added to a weight that already includes a rotor. FM78 and FM78H have retained generic product references of 880 and 968 lb, with operating inclusions unresolved. Obtain complete shaft-, fluid- and accessory-inclusive loads and centers of gravity. The older Deere manual’s implement-code table does not supply a third-party mower code or a universal weight allowance.
FM2572’s 42-hp threshold lies above both PTO references but below the current 45-hp engine label. Its 72-inch cut is only 2 inches wider than FM78, so the unresolved horsepower basis and complete load matter more than a larger model number. FM2584 starts at 49 hp, above both available bases. Land Pride’s hammer material-capacity sources also conflict between 1.5 and 2 inches; neither figure is used here as a proven advantage or a promise at the tractor’s power.
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 John Deere 3046R’s 34.1 PTO hp and 45 engine hp are both inside that range, so the basis does not change the result. Its published lift at 24 inches, 2,200 lb, carries that weight with 901 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. The John Deere 3046R’s 34.1 PTO hp is inside all three. Its published lift at 24 inches, 2,200 lb, carries even the 390-lb EF125 with 1,810 lb to spare. Betstco listed them at $1,462, $1,547 and $1,632 on November 14, 2026, with the PTO shaft included.
