The 18-hp Terex TC20 compact crawler excavator is designed with a top-mounted boom cylinder to provide maximum protection during operation. The boom on the TC20 is offset to the right in order to provide improved visibility to the operator. A quick-couple bucket adaptor makes it easy for bucket and attachment changes, and this unit is plumbed with an auxiliary hydraulic circuit with open (pressureless) retune to provide additional flexibility in adding attachments. The TC20 has an operating weight of 4,455 pounds with a maximum dig depth of 8 feet, 2 inches and a maximum reach of 14 feet, 4 inches. It has a bucket capacity of 1.38 to 6.18 cubic feet.
