Tractors over 65 PTO or 85 engine hp: the chippers and flail mowers that still fit

13 tractor configurations here have over 65 PTO hp or 85 engine hp, the published ceilings of WoodMaxx FM-78 and Wallenstein BX72S. Wallenstein’s BX102S and BX102RI and Blue Diamond’s 403740 are rated above them; past those, it comes down to chippers with no published maximum.

The ceilings

WoodMaxx rates its FM-78 family at 30–65 PTO hp and Farmer-Helper its FH-EFGC mowers to 65; Wallenstein rates BX72S at 50–85 engine hp; Land Pride rates FM2560, FM2572 and FM2584 to 80 hp, and Farmry its 87-inch HFS87 to 85, neither saying engine or PTO. Three attachments here are rated above those: Wallenstein’s 10-inch BX102S (80–120 engine hp) and hydraulic-feed BX102RI (75–120 on its page, 80–120 in the manual’s table), both Category II, and Blue Diamond’s 87-inch heavy-duty 403740 flail (75–100 hp, basis unspecified). This site does not screen past a published maximum, so a tractor over one is excluded rather than assumed approved.

BX102S, BX102RI and the 403740

Wallenstein’s BX102S screens on 11 of the 13 configurations, every one with 80 or more engine hp, the BX102RI on 11, and Blue Diamond’s 403740 on 11; on 3 of those the engine is over 100, so the 403740 passes on PTO power only. All three are heavy, 1,143, 1,950 and 1,763 lb, so check lift and front ballast.

Chippers with no maximum

WoodMaxx publishes minimums and a 50+ full-capacity line for WM-8H, WM-8M, MX-8800 and MX-9900 but no maximum, so they pass all 13 configurations. Woodland Mills lists WC88 as 35–100+ PTO hp; it lists Category 1 only, so it screens on the 5 whose hitch converts to Category 1 and not on the Category 2-only tractors.

Engine or PTO

Land Pride’s FM25 tables give no basis. The site keeps a mower when one tractor figure is inside the range, so John Deere 5090E, Kubota M5-091 and Massey Ferguson MF 4709 keep FM25 matches on PTO power while their engines are over 80. Farmry’s HFS87 (30–85 hp) screens on 9, 6 of them on PTO power only. Ask Land Pride or Farmry which figure it means before buying.

A flail mower for each

Every one of the 13 configurations has at least one flail mower here that passes. Above 85 PTO hp, on LS MT7101, Massey Ferguson MF 4710, Kubota M5-111 and John Deere 5105M, Blue Diamond’s 403740 is the only one; on LS MT7101, Kubota M5-111 and John Deere 5105M it passes on PTO power alone, since the engine is over its 100-hp ceiling.

No maximum is not approval

An open-ended range only means the maker did not publish a ceiling. Ask which shear bolt or slip clutch the PTO shaft carries, whether it is rated for the tractor’s PTO power, and whether the maker approves the pairing in writing.

Take these questions with you.

  1. Does the attachment publish a maximum, and on which horsepower basis?
  2. Is the PTO shaft’s shear bolt or slip clutch rated for the tractor?
  3. Is the tractor’s hitch Category 2 only, or convertible to Category 1?
  4. Will the maker approve the pairing in writing?

Keep these questions with your exact tractor and attachment details.

FIELD GUIDE

Shear bolt, slip clutch and overrunning clutch: what is included?

Protection labels describe different jobs in a PTO attachment. A shear-bolt device and a friction slip clutch limit overload in different ways; an overrunning clutch addresses the rotating implement’s inertia as the drive slows. Ask which components are supplied and where they are fitted. One line saying “clutch included” may leave an important part of the package unidentified.

Read the guide →FIELD GUIDE

When the tractor is too strong: attachment maximum horsepower

Most horsepower checks look at the minimum. Many small chippers and flail mowers also publish a maximum, and a larger tractor can be outside the range for a lighter attachment. Treat the maximum as a published limit with its own horsepower basis. Ask the maker before assuming a light attachment is the safe choice.

Land Pride FM2560, FM2572 and FM2584: when engine or PTO hp decides the fit

Land Pride rates the FM2560, FM2572 and FM2584 flail mowers from 33, 42 and 49 hp without naming engine or PTO power in its manual. On this site 51, 59 and 44 tractor configurations clear those minimums on engine power but not on PTO power.
