Advantages of Prairie Dog Boring Machines Small, lightweight and inexpensive compared to competitive products Carbide tipped bits and Back Reamers allow the machine to handle boring through the toughest conditions (including rocks) Very low operating costs Easy to operate, 1-2 operators can handle and operate the machines (except for the heavier models) Ideal machines for non destructive boring with Low Environmental Impact, No road cuts required. Sturdy Frames and long operational life Operates Above or Below Ground Best suited for : Laying water and sewerage lines Electrical conduits and wires Irrigation lines and conduits/pipes Telephone lines Gas lines Parks

How it works- Simple 7 step procedure Step 1: Dig trenches on either side of the road up to desired depth, one trench to accommodate the machine and the other for come-out hole. Come out hole Trench for machine

Step 2: Lower the machine into the trench and attach the first Drill Rod and Pilot Bit at the end. Attach the water hose and start engine. Start moving the machine forward.

Step 3: As each joint of Drill Rod is pushed into the ground a new one is added behind.

Step 3: (Contd..) Keep on adding Drill Rods until the Pilot Bit reaches the come-out hole.

Step 4: Remove the Pilot Bit and screw on the Backreamer and a cable swivel. If you need a cable to pull a swab or the pipe into place it can be attached to the swivel and pulled back while backreaming

Step 5: Start moving the machine backwards and start removing the Drill Rods as each rod becomes completely exposed (at machine end). Continue this process until the backreamer emerges.

Step 6: Once the Backreamer reaches the start point cleanup the hole with a Pullbar/plate (if required).

Step 7: Slide in the pipe while the hole is still lubricated with slurry Note: The above steps are for illustration purpose only. Please read the user manual and safety instructions (supplied with the machine) before operating.

Wheeled machines will need a trench leading up to the bore entry long enough for the drill stem to sway and level out. Drill rod guides are used to level and align the rods at the point of entry. Adding and remove rods as necessary when boring the pilot hole and backreaming.
