The OFM36 feature hammer knives with a 1" cut height and a 2.5" cut capacity. The unique float capabilities allow the mower to follow the terrain for an even cut on sloped surfaces. The reverse rotor rotation carries the cut material up and over the rotor, directing it downward to minimize thrown debris. The deck has an operational range of 90° up and 65° down making it a good solution for ditches, roadsides, tree lines, and vineyards.
