Zusammenfassung:	A method of reducing speed in a hydrostatic drive work machine, and a hydrostatic drive work machine are provided. The method includes the steps of retarding the work machine by at least one of, upstroking a variable displacement hydraulic motor thereof, and downstroking a variable displacement pump coupled with the motor. An offgoing clutch pressure is dropped after each of the motor and pump displacements reaches a predetermined point. The steps of slowing the work machine are carried out by adjusting the respective displacements at rates based on a predetermined acceleration limit and/or a predetermined jerk limit of the work machine. The hydrostatic drive work machine further includes an electronic control module having a control algorithm recorded thereon for to neutral.
