This European Standard specifies the accuracy of the performance measurement system of road service area maintenance equipment described in the scope of CEN\/TC 337 and used for:<\/p>\n
grass-cutting and brush-cutting;<\/p>\n<\/li>\n
mechanical plant-cutting.<\/p>\n<\/li>\n<\/ul>\n
This equipment is mounted on self-propelled carrying vehicles and is designed to cut and shred grass, brushwood, trees, saplings and bushes in road service areas.<\/p>\n
This European Standard does not cover the collection and transportation of shredded grass.<\/p>\n
