Abstract
Chopping blade (), having a basic body (), which has a fastening portion () for fastening said chopping blade to a chopping drum and a cutting portion () which is angled in relation to the fastening portion, and having a crop-guiding element () which is fastened to the fastening portion () and is intended for guiding chopped harvested crop, wherein a guide surface () of the crop-guiding element () has a curved contour. A distance (a) between the beginning of the guide surface () of the crop-guiding element () and a transition edge () between the fastening portion () and the cutting portion () of the basic body () is between 4 mm and 8 mm. The guide surface () runs rectilinearly in a first portion () with a length (b) between 4 mm and 8 mm, wherein said first portion () encloses an angle (α) between 18° and 22° with the fastening portion (). The first portion () merges into a concavely curved second portion (), the radius of curvature (Rx) of which is between 21 mm and 25 mm and which has a wrap angle (β) between 29° and 33°. The second portion merges into a concavely curved third portion (), the radius of curvature (Ry) of which is between 18 mm and 22 mm and which has a wrap angle (γ) between 24° and 28°. The third portion merges into a convexly curved fourth portion (). A maximum height of the crop-guiding element is between 24 mm and 30 mm.
