Detailed Description & Applications

Overview

The Used CAT Bulldozer D7 series (D7, D7H, D7G, D7R) presents a balance of proven power, versatility and serviceability for mid-size earthmoving tasks. Powered by a turbocharged C9 Acert diesel engine delivering 194 kW (275 hp), the machine combines reliable traction and blade control for grading, pushing and clearing across a variety of site conditions. With a semi-universal blade and a robust undercarriage, the D7 family remains a preferred choice for contractors seeking dependable performance from pre-owned equipment.

Key Features

• Turbocharged C9 Acert engine: efficient power delivery and proven fuel economy for sustained workloads.

• Semi-universal (SU) blade: adjustable for slicing, carrying and finishing tasks, suitable for bulk earthmoving and profile grading.

• Robust drivetrain and LS transmission: consistent torque transfer and manageable service intervals reduce downtime.

• Optimized size and weight (24.96 t): provides stability while remaining transportable within standard freight dimensions.

• Top travel speed suited to job site mobility: 10.54 km/h forward (approx. 6.2 mph) and 13.58 km/h reverse for efficient repositioning.

Operational Advantages

These used CAT D7 variants deliver a clear return on investment by combining durability with straightforward maintenance. Under typical operating cycles, the C9 Acert engine tolerates heavy loads and extended runtimes, while replacement parts and technical know-how remain widely available due to Caterpillar’s global presence. The machine’s control layout is intuitive for trained operators, shortening familiarization time and improving on-site productivity.

Applications and Target Users
