  • Patent number: 8132456
    Abstract: A fuel level indicator for riding lawn equipment with a fuel tank pivotably mounted under the operator seat. A fuel level indicator arm is pivotably mounted under the fuel tank and has a first end contacting the fuel tank and a second end extending through an opening in front of the operator seat. A scale on the opening indicates the fuel level corresponding to the location of the second end of the fuel level indicator arm. A pair of tension springs are attached to the fuel tank and partially support the fuel tank.
    Type: Grant

  • Patent number: 4547716
    Abstract: A windshield cleaner control for a vehicle in which signals from separate washer and wiper actuating switches in the vehicle passenger compartment are voltage multiplexed on a single electric conductor through the firewall to washer and wiper actuating circuitry in the vehicle passenger compartment. A wiper actuating path is established including, in series, a source of electric power, a wiper motor actuating coil relay, the park switch and the washer motor, the internal impedance of the actuating coil being sufficiently greater than that of the washer motor that the latter is not activated by current flow through the former. The parallel wiper and washer switches are connected in series between the source of electric power and the electric conductor, park switch and washer motor, but a resistor in series with the wiper switch similarly prevents activation of the washer motor by the wiper switch.
