Upgrades Made to Ditch Witch JT4020 Series Drilling Machines

The Ditch Witch announces a significant upgrade to two of the company's most rugged, dependable and powerful horizontal directional drilling (HDD) machines: the JT4020 Mach 1 and JT4020 All Terrain.

Both units are now equipped with a welded, double rack-and-pinion thrust drive system that is designed to withstand the rigors of long bores and tough soil conditions. Featuring 15-ft (4.5 m) drill pipe, the rubber-tracked JT4020 Mach 1 has the power and stability to pull multiple conduits up to 1000 ft (305 m) in a single pass, assisted by a cruise-control feature that maintains thrust and rotation settings. The JT4020 Mach 1 features touch-sensitive, variable-speed, electric-over-hydraulic controls that minimize operator effort, with thrust/pullback and rotation controlled by a single lever.

With patented features such as a two-pipe rock-drilling system and an integrated electronic system with cruise control, the 190-hp (142 kW) JT4020 All Terrain can efficiently install utilities underground at up to 1000 ft.

The JT4020 All Terrain’s patented mechanical rock-drilling system provides more power to the bit than any other rock-drilling system in its class. The new thrust drive system provides exceptional low-speed drilling control plus higher speeds for rapidly loading drill pipe.
