A 4-in-1 multi-use flail mower is a single tractor mower that works in four modes: in-line field mowing, verge mowing, ditch mowing, and bank and hedge mowing. The Ryetec Professional Multi Use Flail Mower (MUP) achieves this with hydraulic offset and incline of the mowing head, and suits agricultural and municipal work.

The MUP flail mower has a breakback safety system and a hydraulic safety device with a nitrogen accumulator, so the head can swing back when it strikes an obstacle. The double HARDOX steel frame with counter knife, forged 15 mm anti-wear skids and CE safety protections add durability for arduous verge and bank work.

Ryetec's Mini Flail Mower suits compact tractors from 12.5 hp, with minimums of 12.5–18 hp across its 960–1600 mm widths. The Professional Flail Mower needs 18–30 hp for 1.2–1.8 m. The HD Professional needs 35–55 hp for 1.6–2.0 m, the Contractor Flail Mower suits 30–130 hp up to 2.8 m, and the Triflex gang mower needs 70–80 hp for 4.2–5.0 m.

Y flails are the standard choice for general grass mowing. Paddle flails give a finer lawn finish. Hammer or cast Delta flails are heavier and suit long grass, scrub and prunings; Ryetec Contractor hammers shred shoots up to 5–6 cm. Scarifying blades remove thatch from turf.

A flail mower uses many small flails on a horizontal rotor, chopping material finely and spreading it evenly, so it handles long grass, scrub and prunings and leaves a tidier finish. A topper uses one or two large blades on a vertical shaft and is mainly used for topping pasture.

For steep banks, the ROBOFOX remote control flail mower works on slopes up to 55° (ELECTRA) or 45° (HYBRID), operated from up to 150 m away. For rough or narrow ground, the Peruzzo Motofrog is a walk-behind flail mower with a 75 cm cut. Offset and multi-use flail mowers reach verges, ditches and banks from the tractor.
