A method is provided for controlling a self-propelled work vehicle comprising a work attachment and at least left and right ground engaging units driven by respective first and second drivetrains. Upon determining transition from a first operating mode to a second operating mode (e.g., creep mode), the method includes selectively derating at least a portion of the drivetrain speed commands corresponding to propulsion of the work vehicle (e.g., the average of left and right track speeds), independent of a portion of the drivetrain speed commands corresponding to steering (e.g., the difference between the track speeds). The derate value may optionally be applied only to propulsion commands that produce forward motion, and not for reverse motion. Separate (non-zero) derate settings may optionally be provided for reverse and/or steering functions. Derate functionality may optionally be implemented upon detecting particular types (e.g. dozer) of attachments, or an associated work state. 113 18122 116 114 <- 120
