Rotary harrow

摘要

Rotary harrow with a plurality of implement rotors which are arranged next to one another and which are driven by spur wheels arranged on the shafts of the implement rotors. So that spur wheels for rotary harrows can be produced as cost-effectively as possible, provision is made for designing the spur wheels (11) in two parts, one part (14) which has the teeth (13) being produced from material of low strength in a non-cutting manner and the other part (16) which has the hub (15) being produced from metal of higher strength, and for these two parts (14, 16) to be connected to one another (Figure 2). <IMAGE>
