When you find yourself in a tight space with a tight deadline, the JT520 is your HDD solution. Bury service wire and pull up to two-inch (50 mm) diameter conduit up to 150 feet (46 m), then head to the next job”no costly restoration of lawns, streets, or sidewalks.
KEY FEATURES, JT520
- Compact and maneuverable; the JT520 can be transported with a 3/4-ton pickup and fit through a 36-inch (910 mm) yard gate; ideal for shallow product installations in congested locations.
- Rugged construction for even the most demanding short-range installations.
- 117-inch (2.97 m) compact size allows street setup without blocking traffic.
| DETAILS, JT520 |
|
- Rubber tracks and single-auger anchoring system minimize impact on lawns, sidewalks or asphalt.
- Pipe is designed, built and tested by Ditch Witch engineers and manufacturing specialists for maximum performance with the JT520; 70-foot (21.3 m) bend radius allows the operator to make shallow installations without exceeding pipe capabilities.
- Convenient, pedal-operated lubrication system helps maximize the life of pipe joints and increase productivity.
- Single-handle control operates both thrust/pullback and rotation with variable speed for all functions; operation requires only a tracking equipment operator and a seated drilling operator.
- At only 3150 lb (1429 kg), it”s not intrusive to soft or irrigated lawns.
