The W-FA85 Winton 0.85m Compact Flail Mower is perfect for cutting grass and weeds in paddocks. It is also an ideal tractor attachment for cutting between trees in orchards and vineyards. This is due to its narrow design, which increases its manoeuvrability. This style of mower has Y-blades for pasture topping. However, it is light enough to be run by sub-compact tractors with a low horsepower.

The machine has several Y-blade pairs mounted onto a cylindrical rotor. The spirally arranged Y-blades make for an efficient cut. The multiple blade action creates finer cuttings on overgrown areas. It is also better suited to uneven ground types than conventional topper mowers. The mower is belt driven, meaning that there are drive belts which give power to the blade rotor shaft.

The Winton 0.85m Compact Flail Mower has 2 height adjustable skids to adjust the cutting height between 3cm and 8cm. This also helps to avoid the mower scalping the ground and leave an even cut when mowing. The mower benefits from an adjustable rear roller. This can be adjusted up or down along with the tractor top link arm to change the mower angle and cutting height, as well as helping to avoid blade scalping on uneven areas.
