  • Patent number: 6589136
    Abstract: A power boost control system is provided for an agricultural vehicle with an engine which is normally governor controlled to run at throttle-selected constant engine speed up to a normal or rated engine speed. The power boost control system receives a road speed signal. Power boost is enabled if the sensed road speed is greater than an “on” threshold, above which is considered to be a transport speed. Power boost is disabled if sensed road speed is less than an “off” threshold, below which is considered to be less than a transport speed. When power boost is enabled, the controller will increase maximum power limits to above normal levels, so that, for example, the desired road or transport speed can be maintained as the vehicle goes up a hill.

  • Patent number: 6571836
    Abstract: A fill cup is provided for a fluid filter having a housing and an end plate which enclose a filter element. The end plate has an inlet port for receiving unfiltered fluid and an outlet port from which flows filtered fluid. The fill cup includes a base having openings formed therein, a cylindrical rim which surrounds the base, and a hollow tube which extends axially through the base and rim. The tube forms a stub which projects away from the base and which is adapted to be coupled to the outlet port of the filter. The tube also forms a hollow standpipe which is aligned with the stub and which projects away from the base and into an interior of the cup. When the filler cup is mounted on the filter, the cup openings communicate fluid to the inlet ports of the filter, and the hollow tube prevents unfiltered fluid from directly entering into the outlet port and communicates air from the filter to atmosphere as the filter is filled with fluid.
