Abstract
An interlock circuit on a mowing vehicle or tractor deactivates the engine if a signal from a single backup sensor is interrupted. The mowing vehicle or tractor has an engine, an electric power source to provide electric current to a magneto and an ignition, a transmission connected to the engine and having forward, neutral and reverse operations, a controllable tool drive (PTO) connected to the engine for powering an accessory, and a single backup sensor to provide a signal if no object is detected behind the vehicle. A reverse sensing switch is movable between a first position if the transmission is in forward or neutral, and a second position if the transmission is in reverse. A PTO switch is movable between an on condition for activating the PTO and an off position for deactivating the PTO.
