Previous field scouting can be used to identify areas of field that need remedial treatments such as subsoiling. A variable treatment plan can then be used to work specific areas, saving the cost of cultivating the whole field unnecessarily.

Using lightbar guidance to steer the tractor will bring considerable savings and workrate improvements. A realistic 800mm (2ft 6in) overlap when working an 8m (26ft) wide cultivator represents a 10% loss in output. Over an entire season, working 1,000ha (2,500 acres) that represents 100ha (250 acres) of additional capacity. It also equates to a saving of more than 1,000 litres (222gals) of fuel.
