ABSTRACT:
A tillage implement comprising a plurality of coulters or discs is provided with disc cleaning means to prevent the accumulation of dirt and debris between adjacent coulters or discs. The disc cleaning means can comprise a rotatable belt mounted between adjacent coulters or discs and drive means operable to cause rotation of the belt. The drive means may comprise a drive gear secured to a power source. As the belt rotates, it removes soil from between adjacent coulters or discs.
