Terminal Tractors ECM Programming

Terminal tractors and yard spotters cover the gap between heavy-duty long-haul and stationary equipment. The duty cycle — sustained idle, frequent shifting, low-speed yard operation, PTO duty for refuse or fluid transfer applications — is brutal on aftertreatment systems engineered around highway-cycle operation. Two platforms dominate the segment: the Kalmar Ottawa T2 and the Autocar ACTT XSpotter, both running Cummins B6.7 / L9 power.
