The MD-155 Middle Duty Flail Mower is built for 30–40 HP tractors with CAT I (CAT II bushings included) three-point hitch. It offers a 61″ cutting width and adjustable cutting height from 0.75″ to 2.95″, making it ideal for maintaining large fields, orchards, vineyards, paddocks, and roadside turf up to 1″ brush and up to 40″ grass height.
The MD-155 uses 800 g / 1.76 lb forged, galvanized hammer flails mounted on a 2200 RPM electronically balanced rotor driven by a 3-belt system. A heavy 5.3″-diameter self-cleaning rear roller keeps cut height consistent over uneven terrain. Power is delivered through a Comer gearbox with a 540 RPM PTO, while the rotor runs on SKF ball bearings with CNC bearing seats for durability and smooth operation.
Service is straightforward: a belt-tension inspection window lets you check tension in seconds, and the replaceable counter knife plus front safety flaps improve chopping efficiency while minimizing debris ejection. The mower ships fully assembled in a wooden crate; install the quick-attach CAT-1 hitch (CAT-2 bushings included), fit the safety bars and PTO, and you’re ready to mow ~1.5–3 acres/hour depending on conditions.
