  • Pilot valve mounting which functions as a hot air duct
    Patent number: 6126539
    Abstract: A pilot valve mounting system for lift arm control of a work machine having an operator's cab compartment includes a shroud for the pilot valve mounting. Utilizing the pilot valve mounting system as a hot air duct for bringing hot air to the machine operator's feet and the machine windshield reduces the need for additional components and maximizes usage of space within the operator's cab compartment. A cab heater motor/blower exhausts heated air into the pilot valve mounting shroud whereby the hot air is delivered through directionally movable louvered grills into the operator's cab compartment to direct the heated air where desired.
