In Hopper feeding and Coal loading applications the 655D can load more, move faster and burn less fuel

Multiple work tools are available for increased versatility

Efficient Hydraulic System

Twin pump flow merging hydraulic system increases machine efficiency

The optimized hydraulic system paired with the drive train reduces machine cycle time and increases productivity

Joystick hydraulic control for easy and precise operation

Operator Station

Premium operator station with big space and superior visibility

Patented MAC mount provides less noise and increased comfort

Adjustable suspension seat

Sliding side window and AC with fresh air circulation provide operator comfort

Single lever shifting is flexible and convenient

Adjustable air flow outlet delivers better defrost performance

Reliable Drivetrain

Countershaft transmission with upgraded core components provides high reliability

Large rim-pull in 1st gear and higher speed in 2nd gear provide high efficiency for load and carry applications

Clutch cutoff selection switch ensures stable and safe operation

Torque convertor structure is simple and efficiency is high

The SEM designed and built axle provides best in class performance in heavy duty applications

Advanced Cooling System

The standard cooling package provides high reliability in 50℃ ambient conditions.

Shock pad mounts ensure reliability under severe applications

Solid Structure

Structures undergo Finite Element Analysis (FEA) and On Machine Stress Analysis (OMSA) to ensure durability

Performance Series (PS) buckets improve loading capability

Serviceability

System pressure test ports are standard

Big angle engine hood side open door provides easy service access
