TMG flail mowers: the 30–60 hp table and the 50-PTO-hp manual cap

TMG lists its TFM60 and TFMS50 for 30–60 hp tractors without naming a basis, but both manuals say tractor power must not exceed 50 PTO hp. 3 configurations on this site are over the cap while inside the table.

Two TMG numbers

TMG’s product pages and tables give 30–60 HP. The TFM60 and TFMS50 manuals each state, on page 6, that tractor power must not exceed 50 PTO hp. The manual is the more specific statement, and this site applies it.

Over the cap, inside the table

A tractor with 51–53 PTO hp and no more than 60 engine hp, such as the Kubota L6070 Premium, Case IH Farmall Utility 60A or Yanmar YT359 (working-speed rating), satisfies the 60-hp table but not the 50-PTO-hp cap. The screen excludes it.

Under the cap, engine over the table

A tractor with 50 PTO hp but 64 engine hp, like Case IH’s Farmall Utility 65A, is at the cap and over the table on engine power. The screen holds it for review: ask TMG which limit governs.

Why a PTO cap

A flail mower’s gearbox and driveline are sized for the power the tractor can deliver through the PTO. Running over a stated PTO limit goes against the maker’s own guidance.

Take these questions with you.

  1. Will TMG accept my tractor’s PTO hp under its 50-hp cap?
  2. Does the 30–60 HP table mean engine or PTO?
  3. Is a slip clutch fitted on the driveline?
  4. Would a mower rated to 65 PTO hp suit the tractor better?

Keep these questions with your exact tractor and attachment details.

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.

Tractors just over 50 PTO hp: which chippers and flail mowers drop out

Several attachments stop at 50 PTO hp: Woodland Mills WC68 and, by their manuals, TMG’s TFM60 and TFMS50. Tractors from about 51 to 55 PTO hp, such as the Kubota MX6000 (51.8), M4D-061 (52) and L6070 Premium (53), are over those limits by a few horsepower, and over the 45-hp chippers and mowers by more.

Tractors at exactly 50 PTO hp: TMG’s cap, WC68’s ceiling and WoodMaxx’s 50+ line

Three limits meet at 50 PTO hp: TMG’s manual cap on TFM60 and TFMS50, Woodland Mills WC68’s maximum, and WoodMaxx’s 50+ full-capacity line. Tractors rated exactly 50, such as the Kubota M5660SU and Massey Ferguson MF 2M.65, sit on all three at once.
