  • Safety gear change apparatus for snow clearing vehicles
    Patent number: 4030380
    Abstract: A safety gear transmission having a plurality of forward gears and a single reverse gear is provided with preselection control means for operation of the reverse gear by means of which the reverse gear is automatically actuated in response to a given stimulus for a sufficient time to assure that the vehicle, or at least the snow clearing unit moves free of the obstacle. The control means may operate either on sensing the presence of a dangerous obstacle itself, or on the changing directional state of the snow unit occurring as a result of the vehicle driving into such an obstacle, or in response to the manual operation of a manual control member.
