ScanStone destoners are high-performance soil separation machines designed to remove stones and clods from agricultural beds, primarily for root crops like potatoes and carrots. Based in Scotland, ScanStone manufactures these machines to operate in harsh, stony conditions to enhance crop harvesting efficiency, reduce tuber damage, and improve machine reliability.
The ScanStone destoner range comprises of six models. Starting with the 3 webber, which is a lightweight nimble machine for smaller fields, we have 4 webber, 5 webber S and 5 webber L in the web category of our machines. We also have a fixed star machine and a vari-star machine. Each machine can come with various specifications and with or without a stone box.
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.
