HX50 Vacuum Excavator
Featuring superior power and versatility, the Ditch Witch HX50 is equipped with a 49-hp Kubota® diesel engine to support all machine functions – from potholing and small-slot trenching applications to HDD fluid and jobsite debris cleanup. The machine offers outstanding suction and water pressure and features minimal noise disturbance. Plus, it incorporates customer-driven enhancements to meet the unique needs of operators using the machine daily.
Key Features
  • The HX50 is powered by a 49-hp (36.5-kW) Kubota diesel engine to support all machine functions from potholing to cleanup of a variety of soils, HDD fluids and jobsite debris.
  • The HX50 provides 20 percent more fuel capacity than its predecessor for improved productivity and fewer refueling stops during the workday.
  • New with the HX vacuum excavation line, a patent-pending make/break seal design optimizes air flow for increased efficiency, and simplified plumbing.
  • An auto-clutching feature disengages the water pump when water is not in use, allowing full system power to the blower for improved productivity.
  • A now standard reverse-flow feature allows quick and easy spoil offloads for improved productivity.
  • A standard, cyclonic three-stage filtration system cleans the air before it reaches critical components. It is comprised of the debris tank, cyclonic filter, and 0.5-micron washable vacuum filter – offering the industry’s best filtration for maximum protection of key components.
  • Featuring outstanding suction, the HX50 is equipped with an efficient 1,005-cfm blower.
  • The HX50 is designed for a wide range of applications, including potholing, storm-drain cleanout, HDD site cleanup, water-leak repair, valve-box and utility-vault cleanout, commercial and residential debris cleanup, and landscaping and posthole digging.
  • The HX50 is equipped with an 800-gal debris tank to meet the requirements of any size soft excavation or cleanup job. 800-gallon configurations includes a standard configuration equipped with a 200-gal freshwater tank and 20K GVWR trailer. A heavy configuration equipped with a 400-gal freshwater tank and a 24K GVWR trailer.
  • All trailer configurations are NATM compliant and are offered with an optional toolbox for extra storage.
  • An optional jib boom is available on all HX50 configurations and has exclusive dual articulation, providing the widest range of motion in the industry, as well as a hose restraint, which helps control the unit’s hose while working.
  • A power boom, available on the 24K GVWR trailer package, features an advanced design that reduces manual labor for the operator. The boom is hydraulically powered with a 330-degree rotation and includes a self-locking gear, acting as a boom brake, to restrain motion of the boom and maintain its desired position.
  • The machine can easily be configured to accommodate operator controls on either the left or the right side to meet each contractor’s individual needs.
  • Featuring a low-profile design, the machine’s full unit height is reduced. This eases maneuverability and allows the unit to fit in height-restrictive areas, without compromising ground clearance so operators can more easily avoid ground-level obstacles.
  • An exclusive, lockable hose-storage design allows operators to store the hose flat and straight inside the unit frame – a direct customer-driven enhancement. The vac door also features lockable, convenient storage for unit tools, including the vac tube and digging lance.
  • Patent-pending, advanced door linkage automates lockout when fully opened, without requiring any additional effort from the operator.
  • The HX50 now has hydraulic controls located at the rear of the units, enhancing operator visibility.
  • An optional dual work light features two LED floodlights in the back of the vac unit for use in dark or night conditions.
  • The HX models feature improved serviceability as all maintenance points are more accessible with a liftoff power pack door design.
  • Standard on the HX50 is a cyclonic filtration system that minimizes filter cleaning frequency, while providing superior filtration, resulting in increased productivity.
  • An optional spare tire with a carrier allows easy access to a spare when needed, reducing downtime.
