| 摘要 |
A rotor for a rotary mower of a kind adapted to cut a crop at two levels has sets of cutting blades (27, 28) with interposed crop deflecting ramps (22) to throw upwardly crop cut by the lower blades (27) above the level of the upper blades (28) to minimise multiple cutting or mincing of the crop. The blades (28) are angularly disposed relative to the blade (27) so as to ensure that at least a major part of a crop is first cut at the upper level. <IMAGE>
