Caterpillar says its new D11T dozer and D11T CD (carry dozer) set the standard for productivity, durability, reliability, safety, and operator convenience with design refinements that include enhanced auto shift, a dynamic inclination monitor, automatic climate control, and available automated ripper control. Blades range in capacity up to 57 cubic yards, operating weights range up to 248,456 pounds, and the C32 engine meets Tier 4 Final emissions standards. Both units feature an “OK-to-Start” system that electronically checks critical fluid levels.
