FEATURES AND BENEFITS
Feature: Compact Size
Benefit: The D20x22 is the only drill on the market that provides 85 hp (63 Kw) in a 48-inch (122 cm) wide machine. Its small size allows it to be used in congested areas where other machines cannot be used. The D20x22 can be trailered side by side with the MX125 drilling fluid system, allowing the use of smaller support equipment.

Feature: Rack and pinion thrust drive
Benefit: The narrow rack and pinion thrust drive design utilizes replaceable gear track sections. If damage occurs to a track section, an operator unbolts the section and replaces it. Some competing manufacturers weld the gear track to the rack.

Feature: Two-Speed Rotational Operations
Benefit: The two-speed rotational operations allow the operator to choose a high RPM to do the pilot bore, and then select a high torque for the pullback.

Feature: 60-Gallon (227 L) On-Board Water Tank
Benefit: A 60-gallon (227 L) on-board water tank provides clean water supply for easy clean-up and can supply ample drilling fluid for smaller jobs.

Feature: 2200 ft-lb (2983 Nm) of torque
Benefit: With 2200 ft-lb (2983 Nm) of torque, the D20x22 has enough power to turn cutting tools in demanding soil conditions and longer distance bores. The D20x22 has enough torque to accomodate larger backreamers than other machines in this HDD class.

Feature: Pullback
Benefit: The D20x22 has 20,000 lb (9072 kg) of pullback for longer, heavier product.

Feature: Operator's Station
Benefit: Elevated operator's station with swing-open design offers the operator comfort and a clear forward view of the drilling operation. Thrust/pullback, rotation and water-pressure gauges are conveniently located to the right side of the operator for simple reference during boring operations. Operator's presence switch located in the operator's seat stops thrust/pullback and rotational functions when the operator leaves the seat. The strike alert system located at the operator's station warns the operator of an electrical strike.

Feature: Simplified Electrical System
Benefit: By implementing a CAN Bus electrical system, approximately 20 percent of the wiring is eliminated. CAN Bus systems have been used for years in the airline industry and on construction equipment, such as excavators.
