Drivers passing through the Carson, N. Dak., area last summer were treated to a strange sight - a 165-ft. long section of a center pivot irrigator being pulled by a pickup down the highway.
  The operator was Loron Skretteberg, who had recently bought a used center pivot system with the intention of moving it to his farm. He had taken the 8-tower pivot system apart and was moving it one span at a time to his farm 35 miles away. He pulled it at speeds up to 50 mph.
  "I got lots of strange looks from people who wondered just what was going on," says Skretteberg. "It took eight trips to move the eight towers. I made two trips a day. Most farmers who buy used center pivots dismantle the systems piece by piece, which is a very labor intensive job. I couldn't do that because it was summer and I needed to start irrigating my crops. I didn't have much time so I came up with this idea."
  To support each tower as he towed it, he made a saddle out of channel iron that fits on top of a 2-ton front truck axle. A battery-operated winch, with its cable tied to a steering rod at each end of the truck axle, was used to steer the irrigator around corners. Skretteberg sat on the truck axle and operated the winch, while another person drove the pickup.
  "It worked great. I find it's much cheaper to buy a used center pivot irrigator and move it than it is to buy a new one," says Skretteberg. "If I hadn't used this idea, I would've had to remove all braces from the irrigator, mark each piece, put them on a truck, and then put everything back together again. It would have been a labor intensive and time-consuming job. The bolts on old center pivots get old and rusty, so sometimes you have to use a torch to cut them off. Also, it's always easier to take something apart than it is to put it back together again.
  "I also bought a used 5-tower center pivot equipped with 185-ft. spans and moved it even farther - 110 miles. For much of the way I had to travel on an interstate freeway."
  He used 8-in. sq. tubing to build the frame of the center pivot mover. A steel tongue comes forward off the axle and supports a pipe, which is secured to the center pivot's main pipe to hold the entire frame rigid. He welded channel iron to the back side of the axle to form a "saddle" for the center pivot axle that keeps it about 3 ft. off the ground.
  He cut the truck axle in half and welded in new material to lengthen it by 3 ft. for more stability. He also lengthened the truck's tie rods.
  To move each tower span, he first disassembled the tower spans. Then he used a front-end loader and chain to lift the center pivot axle high enough that he could remove the pivot wheels and back the truck axle under it. The two axles were chained together. Then he used the loader to lift the opposite end of the span onto a fifth wheel-type hitch on the pickup flatbed.
  "I was able to set up fast. I could come into the field and be ready to leave in only about 45 minutes," says Skretteberg. "For safety I had another pickup driving behind me with flashers. No special permits were required.
  "The center pivot axle is 14 ft. wide, so on the highway I tried to stay over to one side as much as I could. Whenever I came to a corner, I used a two-way toggle switch on the winch to make the wheels steer left or right. Once I got home I took everything off the truck axle, set it back on the ground, and put the irrigator wheels back on. Then I went back to the field to get another span."
  He paid $500 per span for both center pivots. Most of the electrical components weren't usable so he had to install new tower boxes. "I had to invest some money in the center pivots but it was still cheaper than buying new. My total cost was about one fourth the cost of buying new."
