The published range

WoodMaxx lists the FM-78 hammer at 30–65 PTO hp. WoodMaxx gives the range in PTO horsepower, so this site compares each tractor’s published PTO rating.

How 294 configurations screen

Of the 294 tractor configurations profiled on this site, 183 are not excluded, 98 fall under the minimum and 13 are over the maximum. Not excluded is not approval: most pairings still need the maker or dealer to confirm the setup.

By brand

Configurations not excluded, by brand: Case IH 26 of 31; John Deere 23 of 39; KIOTI 25 of 37; Kubota 21 of 39; LS 21 of 32; Mahindra 6 of 17; Massey Ferguson 18 of 29; New Holland 14 of 18; TYM 22 of 37; Yanmar 7 of 15.

Closest exclusions

The configurations closest to the line are just under the minimum: Mahindra 1640 gear † (29.9 PTO hp), New Holland WORKMASTER 35 gear † (29.7 PTO hp), New Holland Boomer 35 gear (29.7 PTO hp); just over the upper limit: LS MT774 power shuttle cab (65.6 PTO hp), Massey Ferguson MF 4708 power shuttle (67 PTO hp), TYM T5075 power shuttle cab (67.1 PTO hp). A newer spec sheet, a different transmission or the maker’s confirmation can change these.

Weight and hitch

This site retains a 880-lb weight for the FM-78 hammer. No configuration that clears the power range lists less lift 24 inches behind the hitch than that; tractors with no published 24-inch lift are held for review. It mounts on a Category 1 and 2 hitch.

Take these questions with you.

  1. Which exact configuration and transmission is the tractor?
  2. Does WoodMaxx confirm the FM-78 hammer at the tractor’s rating?
  3. What is the complete weight with the PTO shaft?
  4. What does the dealer list for lift 24 inches behind the hitch?

Keep these questions with your exact tractor and attachment details.

FIELD GUIDE

Attachment weight vs. tractor lift capacity

A product weight below a three-point lift rating is only the start of a load check. The two figures may describe different measuring points, configurations or operating conditions. Subtracting them does not produce an approved safety margin.

Read the guide →FIELD GUIDE

Choosing flail mower width for your tractor track

A mower’s model name is not a tire-coverage measurement. The useful comparison is actual cutting width against the outside rear-tire span of your tractor, plus the offset and overlap the job needs. Measure the machine you own before using a generic model recommendation.

Read the guide →FIELD GUIDE

Meeting an attachment’s minimum PTO horsepower exactly: what zero margin means

A tractor whose PTO rating equals or barely exceeds an attachment’s minimum is inside the published range, and nothing more. Several makers attach separate capacity statements well above their minimums. When the margin is zero or one horsepower, also check the source of each number and what the maker expects at that power.
