Version three of Househam’s TMC display is now Linux-based. Apart from using Total Machine Control software to govern and analyse sprayer performance, it can optionally host Househam’s Fieldmaster GPS guidance/variable rate control package. This — which can manage Househam’s Spray Pilot autosteer — runs faster and smoother under Linux, says the company. The new unit is standard in the company’s Merlin and Air Ride machines.
