PROBLEM TO BE SOLVED: To provide upshift in a hydrostatic drive work machine. SOLUTION: This invention relates to a method of upshifting the hydrostatic drive work machine. This method includes the step of adjusting a high clutch pressure of the work machine toward an elevated pressure. While the high clutch pressure is adjusted, motor displacement in a hydrostatic drive of the work machine is increased toward predetermined motor displacement. The hydrostatic drive work machine is also provided, including a control module having a computer readable medium with a control algorithm recorded thereon. The control algorithm includes a first means for controlling the motor displacement based on a throttle position of the work machine, and a second means for controlling the motor displacement based on a factor other than the throttle position.
