Farmry LFS flail mowers: is 35 hp engine or PTO?

Farmry rates its LFS45, LFS53 and LFS61 flail mowers at 15–35 hp without naming engine or PTO power on its product pages or in its manual. 44 tractor configurations on this site are inside 35 on PTO power and over it on engine power, so the answer depends on Farmry’s meaning.

What Farmry publishes

Farmry’s product pages and Rev 1.7 manual give a 15–35 HP tractor power range for the LFS line. Neither says engine or PTO, and the 30 HP gearbox rating is a separate component figure.

How this site screens it

A tractor is excluded only when both its engine and PTO figures are over 35. The configurations in the table are held for review: on PTO power they fit, on engine power they do not.

Who falls in the gap

Mostly 36–45 engine-hp compacts with 26–35 PTO hp: Kubota’s L3902, John Deere’s 2038R, 3038E and 3046R, KIOTI’s CK4020 and Mahindra’s 1635 among them. Ask Farmry before ordering.

Farmry LFP47

Farmry’s heavier LFP47 is rated 25–45 hp, also without a basis. Many tractors in the LFS gap are inside LFP47 on both figures.

Take these questions with you.

  1. Does Farmry’s 15–35 HP mean engine or PTO?
  2. Would LFP47 (25–45 hp) suit the tractor better?
  3. Does my tractor manual limit flail width?
  4. Is a slip clutch included?

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.

Gross or net engine horsepower: SAE J1995, SAE J1349 and engine-rated attachments

Some tractor makers print two engine figures: gross power under SAE J1995 and net power under SAE J1349. The net figure is lower. When an attachment is rated in engine horsepower without naming a standard, a tractor near the line can pass on one figure and fail on the other. Kubota’s MX specification sheet shows both, and the gap decides several screens.

Tractors near 35 PTO hp: Woodland Mills WC88 and Farmry LFS

Woodland Mills WC88 starts at 35 PTO hp and Farmry’s LFS45, LFS53 and LFS61 flail mowers stop at 35 hp, so a tractor near 35 can fit one and not the other. 32 tractor configurations on this site sit between 33 and 37 PTO hp, where a transmission or a spec sheet can move the answer.
