Caterpillar D6T, D7E, D8T track-type tractors
Caterpillar says its new D6T, D7E, and D8T (shown) track-type tractors deliver reduced emissions, higher productivity, and lower operating costs. All three models feature Cat engine and aftertreatment solutions to meet Tier 4 Interim emissions standards. The D6T and D7E use the Cat C9.3 ACERT engine, and the D8T uses the Cat C15 ACERT engine, featuring net horsepower ratings of 205, 235, and 310, respectively. All models offer optional Key Off Regeneration, as well as a delayed engine shutdown timer and engine idle shutdown timer. The cabs feature streamlined dash displays and instrumentation, enhanced operator efficiency, and more commonality across the tractor line up.
