Abstract

In the case of a soil cultivation device with multiple harrow tines, the harrow tines are fastened to levers, which are mounted to pivot on tie bars of the supporting frame via carriers. The operating position of the harrow tines is defined by the levers being adjacent to tie bars, and the harrow tines are prestressed into the operating position by springs assigned to them in the form of pneumatic cylinders.

Abstract

In the case of a soil cultivation device (1) with multiple harrow tines (10), the harrow tines (10) are fastened to levers (12), which are mounted to pivot on tie bars (3) of the supporting frame (2) via carriers (13). The operating position of the harrow tines (10) is defined by the levers (12) being adjacent to tie bars (3), and the harrow tines (10) are prestressed into the operating position by springs assigned to them in the form of pneumatic cylinders (17).
