Kellfri ATV Flail Mower with Flap — 1.2m Working Width

⚠️ Price includes UK delivery. Customer assembly required.

A robust, field-proven flail mower built for ATV use across pastures, parks and roadsides. The rear flap design allows higher operating speeds, more even grass spread, and reduced belt wear — making it the smarter choice over a standard flail mower. At 238 kg and 28 hardened flails, it handles tough vegetation, tussocks, and uneven ground with ease.

Why Choose the Flap Version?

The rear flap actively releases cut grass rather than allowing it to accumulate under the hood. This means:

• Higher operating speeds compared to a standard ATV flail mower
• Reduced fuel consumption and belt wear
• More even grass distribution across the cut area
• Better performance through tougher, denser vegetation

Built for Longevity

• Grease nipples on all support and rotor roller bearings
• Sealed cover over drive belts
• Easy access for cleaning, servicing, and repair
• Flap at the rear opens via two plate handles on each side

Delivery & Assembly

Delivered in a steel crate box. Price includes delivery to your address. The mower requires self-assembly on arrival — all necessary components are supplied. A support leg is available as an optional accessory (not included).

Tips for Best Results

For normal grass height, mow at 10 km/h for optimal cut quality and belt longevity. For taller or denser growth, raise the mower to its maximum height and make two passes.
