SPIKE-TOOTH HARROW

The spike-tooth harrow is given such a name because of the teeth in which it is made of that stir the soil, resembles long spikes, unlike the spring-tine harrow, one or more of its sections ranging from 120cm to 180cm wide. The numbers of spikes per section of the spike-tooth harrow ranges from twenty-five to thirty-five teeth. The section may be flexible or rigid. The principle behind it is to smooth and levels the soil directly after harrowing with disc harrow in order to provide a suitable seedbed for planting. It is also used to cover small seeds broadcast over the surface. It is an excellent tool for pre-emergence cultivation to break the rain-formed crust and destroy small weeds.
