The TMG-AFM40 ATV Flail Mower makes the cutting of uneven, overgrown and harsh terrain efficient and easy to do. Simple, easy hookup to a 2" ball receiver on your ATV or UTV for use around your home, farm or commercial property. This mower is the perfect attachment for your four-wheeler and turns it into a versatile maintenance machine to keep your property looking sharp.

40" of working width for fast, efficient cutting and 5-point offset capabilities for when you’re working around trees and bush lines or getting close to buildings and garden areas. Cut grass up to 15" in height and leave a smooth, finished surface with the attached heavy-duty rear roller. A two-belt drive system provides efficient energy transfer and reduces slippage for a long-lasting, low-maintenance mower that will last for many years.

64 razor sharp 4" Y-shaped blades are powered by a reliable, electric start 13.5 HP Briggs & Stratton XR Professional Series engine to make sure you get the job done right. The engine is durable and features a Dura-Boreβ„’ cast iron sleeve and cartridge air cleaner that includes a standard pre-cleaner. Ships free from our warehouse in Richmond, BC.
