The JT28 + JT20 Advantage
Two drills. One strategic advantage.
Our fleet includes the Ditch Witch JT28 and JT20 directional drills — compact, powerful machines ideal for a wide range of bore sizes and site conditions. Whether navigating tight urban environments or tackling longer rural bores, our rigs offer the versatility and performance your project demands.
By operating both a JT28 and JT20, we match the right equipment to each job—improving accuracy, reducing risk, controlling costs, and minimizing disruption.
