    Abstract: A compactor vehicle is provided having a plurality of wheels in the form of drums having chopper blades attached thereto in an offset chevron pattern. The offset chevron pattern faces forwardly on the front wheels and rearwardly on the rear wheels thereby providing improved chopping and flattening action when the vehicle is used to prepare land for replanting in forest management or to compact layers or debris and soil when used in sanitary landfill operations. Extension wheels having chopper blades are additionally provided whereby the vehicle may operate satisfactorily under soft soil conditions.

    Abstract translation: 提供一种压实车辆，其具有多个滚轮形式的滚轮，其具有以偏移的人字纹图案附接到其上的切割刀片。 偏移的人字纹图案在前轮上向前并且在后轮上向后，从而当车辆用于准备用于在森林管理中补充的土地时，或者当用于卫生填埋操作时压实层或碎屑和土壤时，提供改进的切割和平整作用 。 另外提供具有切割刀片的延伸轮，由此车辆可以在软土条件下令人满意地运行。
