Electric Gate Trigger
Getting on and off tractors to open and close gates is no longer a problem for Phillip MacDonald, Galatea, New Zealand, inventor of a "triggered" farm gate mechanism that opens the gate at the touch of a bumper and closes it again when a pre-set amount of time has passed.
The sloping V-shaped trigger mounts at the center of the gate. When the front bumper or tractor tire nudges it, an electric switch activates a gate opening mechanism on the gate post. The closing interval can be adjusted so that, if there are animals around, the gate can close quickly behind the vehicle. The mechanism can be fitted to any existing gate and can be electrified.
