Developed in conjunction with Lincolnshire farmer Tony Gent, the patented disc coulter on Weaving Machinery’s new GD (Gent Disc) drill results in low soil disturbance and a draught requirement of 40hp/m. The new coulter design is based on a double disc arrangement. The larger leading outer disc cuts an opening slice in the soil while the smaller inner disc forms an opening for the seed. The lifted wall of the soil is firmed by a single press wheel, which also acts as a depth regulator for the disc coulters. Drilling depth is adjusted by moving a single pin through a bank of holes with a depth range of 0-130mm in 15mm increments. Coulters are individually pressurised by a hydraulic system providing up to 200kg of downwards pressure. With an inter-row clearance of a metre, the company says the coulter is able to work in extremely trashy conditions and cover crops, and can be used on all cultivation systems and soil types. The new GD coulter will be available in either a mounted or trailed format. Available in widths from 2 to 4.8m, and, mounted zero-till machines are a new addition to the company’s portfolio. Fitted with a 1.2t seed hopper, prices start from £24,642. Trailed widths range from 4 to 8m, with prices starting at £42,700.
