Ditch Witch Upgrades JT4020 Mach 1, JT4020 All Terrain

Construction Equipment Guide

Ditch Witch has upgraded two of the company’s 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.

JT4020 Mach 1 Overview

Featuring a 15-ft. (4.5 m) drill pipe, the rubber-tracked JT4020 Mach 1 has the power and stability to pull multiple conduits up to 1,000 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.

Like all Ditch Witch HDD units, the JT4020 Mach 1 has a pipe loader system with hydraulic pipe grippers, single pipe-loading capability, shuttle stops, and automated thread lubrication. When using the Ditch Witch organization’s Fluid Miser drill pipe, the machine uses far less drilling fluid and creates far less job site mess, according to the manufacturer.

The JT4020 Mach 1’s 190-hp (142 kW) diesel engine has sufficient power to drive all functions simultaneously. Its hydraulic, four-point anchor system keeps the unit firmly secured during operation in virtually any soil condition, and its rubber tracks minimize damage to pavement, curbs, lawns, and landscaping.

JT4020 All Terrain Overview

With 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 long range — up to 1,000 ft.

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

The machine is designed to provide increased drilling fluid flow. An onboard pump enables productive drilling at extended distances, while a normal flow rate can be operated simultaneously with thrust/pullback and rotation.

With its hydraulic, four-point anchor system, the JT4020 All Terrain can be firmly secured in all types of ground conditions, including rock, and its adjustable drill frame design allows setup at normal drilling angles without raising the tracks off the ground.
