The Heavy Duty Professional Flail Mower needs 35 hp for the 1.6 m Y flail model, 45 hp for the 1.8 m and 55 hp for the 2.0 m. Hammer flail versions need 40 hp at 1.6 m and 50 hp at 1.8 m. Weights range from 340 kg to 463 kg depending on width and flail type.

The HD Professional flail mower comes with either 5 mm Y flails or 0.6 kg hammer flails, and both cut scrub up to 35 mm. Y flail models carry 96 to 128 flails across the 1.6–2.0 m widths. Hammer models carry 20 or 24 heavier hammers and are offered in 1.6 m and 1.8 m.

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.
