Destoners largely cultivate to a depth of between 10 and 18 inches. This means that it can produce a graded amount of soil to these depths. All the clods, stones and soil goes into the front of the destoner through an intake web. The choice of web pitch, or star configuration will depend firstly on the forward speed of the machine, the quality of the graded soil and the depth of the finished bed.
Using webs to destone will always give a consistent grade of soil, however output can be limited if ground is wet or full of grass fibre. The star system is slightly more complicated to operate, whereby the finished bed is changeable, subject to the forward speed of the machine, the RPM speed of the tractor and the amount of soil in the machine at any one time. The stars generally perform well in grassy conditions, wet sandy conditions or heavy clay conditions.
