Lincs firm Bristows had a new version of its Split-Level subsoiler on display, specifically for establishing crops of oilseed rape.  Up front there is a choice of surface loosening tines or discs, followed by a selection of subsoiler legs — either wide-winged, minimum disturbance or rearward raked. The company’s trademark hedgehog Multi-Tooth Tiller Roll provides initial consolidation and levelling, ahead of pairs of angled disc coulters.  Supplied with seed by a Stocks TurboJet metering unit, the discs are cranked over at a 45° angle, placing the seed in two rows directly in line with where the legs have run. Finally, individual flat roll sections firm up the ground behind each pair of coulters.
