1. An apparatus for providing a detent function on a hydraulic system, the hydraulic system including a hydraulic implement movable between first and second implement positions, comprising:

  • control input means, operable by an operator between first and second control positions, for producing a control input signal indicative of desired movement of the hydraulic implement between the first and second implement positions;

    electronic control means, coupled to said control input means, for receiving said control input signal and responsively producing a valve actuation signal;

    hydraulic control means, coupled between said electronic control means and the hydraulic implement, for receiving the valve actuation signal and responsively providing hydraulic fluid flow to the hydraulic implement;

    wherein said electronic control means includes;

    means for monitoring said control input signal and responsively producing an active detent signal if said control input signal follows a preset pattern; and

    means for receiving said active detent signal and automatically providing a detent function by actuating said hydraulic control means at full displacement in response to receiving said active detent signal.
