How much horsepower do you need for a flail mower?

Most flail mowers require between 25–85 HP, depending on their size and cutting strength. A hydraulic flail mower like the HFSS79 works best with tractors in the 30–85 HP range to power the blades and hydraulic hose for side shifting, especially when cutting through thick grass or brush.

How big can a flail mower cut?

Flail mowers vary in cutting width, typically ranging from 50" to over 90". The HFSS79 provides a mowing width of 79 inches—great for covering large plots efficiently. It’s ideal for handling fields, ditches, and uneven ground while maintaining control and precision.

What is a flail mower best for?

Flail mowers are perfect for cutting tough matted grass, brush, and even small tree prunings. With the HFSS79, you get versatility—thanks to optional hammer blades for making it ideal for maintaining fence lines, orchard rows, and ditch banks.

Which is better, a rotary cutter or a flail mower?

While rotary cutters handle open fields, a flail mower with hydraulic side shift provides more precision and safety. It excels in overgrown terrain, leaves a cleaner finish, and prevents debris from being thrown—perfect for areas where safety and mulching matter most.

With proper care, a flail mower like the HFSS79 can last a decade or more. Farmry supports a full line of replacement parts to keep your equipment in top shape. Regular blade sharpening, belt tension checks, and gearbox maintenance will protect your mower’s key features for long-term use.

How to Choose a 3-Point Flail Mower

When selecting a flail mower, keep these simple guidelines in mind:

1. Know Your Tractor’s Power Range
   Match the mower’s size and weight to your tractor’s PTO rating. For a hydraulic flail mower, 35–85 HP is optimal.
