Volvo’s EC35C and ECR48C compact excavators both use the D2.2D diesel engine rated at 36.3 horsepower, but the 7,800-pound EC35C digs to 11 feet 10 inches from a conventionally designed upper structure, while the 10,700-pound ECR48C can dig more than 13 feet deep from a short-radius house that swings within the track width.
