The digits in the updated Qualidisc range now end with an 01. So what’s changed? We hitched up to the 5.00m version

The Qualidisc short disc harrow is made as a fully mounted, rigid version (2.0, 2.5, 3.0, 3.5 and 4.0m) or folding (4.0, 5.0 and 6.0m) or as a semi-mounted machine (4.0, 5.0, 6.0 and 7.0m). It comes in two flavours, Farmer and Pro, with the latter getting 600mm diameter serrated discs that are suitable for work at depths of 3 to 15cm.
