Abstract
A machine powertrain having a transmission includes a control device responsive to selectively vary the transmission ratio in response to a shift signal. A lift sensor associated with a machine implement monitors an implement position and provides a lift signal. A ground speed sensor monitors the ground speed and provides a ground speed signal. A controller monitors the lift and ground speed signals, compares the lift signal to a predetermined position range, compares the ground speed signal to a predetermined ground speed range and, when the ground speed signal is within the predetermined ground speed range and the lift signal is within the predetermined position range, provides the shift signal causing the selectively variable ratio of the transmission to change.
