Activists’ aerial attack
Farmers are bracing for a major animal rights campaign against their winter grazing practices.
Dutch firm WOPA, whose products are distributed in New Zealand by Veehof, Canterbury, has developed such a machine: the TrimMaster is said to be ideal for tracking over uneven surfaces or working on soft or unstable ground.
In operation, power from a lead-acid battery runs an electric motor for up to about 30 minutes, and this powers a hydraulic pump that feeds oil to track-drive motors in the track unit under each side of the machine.
Although built the same as the standard wheeled unit that rides on its own wheels, the tracked version needs a flat-bed trailer to make the move between jobs and it costs more.
