When truck accessibility is not an option we offer the use of our custom built tractor rig. Fully self contained, this 4-wheel drive rubber tire tractor allows quick set up in a wide variety of site conditions. The turning radius (11ft) and width (5′ 8″) allows this rig to locate in very tight spaces, and the short tower (14′ 9″) allows work in places where the overhead conditions are low. (power lines, trees, etc.) The 40 H.P. John Deere engine provides plenty of power to drill through dense material. This rig also has a wire line sampling system that is fast, and accurate.
