    Patent number: 6199450
    Abstract: A drive line assembly for a work machine is disclosed. The drive line assembly includes an engine driving an engine output shaft and an engine speed sensor which generates engine speed signals indicative of a speed of the engine output shaft. The drive line assembly further includes a torque converter driven by the output shaft which drives a transmission input shaft and a transmission speed sensor which generates transmission speed signals indicative of a speed of the transmission input shaft. The drive line assembly yet further includes a transmission driven by the transmission input shaft and having a first speed clutch, a second speed clutch, and a directional clutch, and a controller. The controller is operable to determine a torque converter ratio from the engine speed signal and the transmission speed signal and determine an engine load based on the torque converter ratio.
