Combine Powers Gravel Screener
Orland Ohe runs his sand and gravel business with the help of a combine. Like a giant gearbox, the old IH 914 pull-type combine transfers tractor pto power to two conveyors and a screener.
  “I used to hire a contractor to come in and screen gravel for me,” says Ohe. “I was able to pick up some used conveyers and a screener to do it myself. Without the combine, I would have needed a big diesel genset and electric motors on all the equipment.”
  Instead, Ohe gutted the 914, stripping away the cylinder, straw walker, sieves and hopper. The grain platform and anything not related to jackshafts, chassis and the pto were gone.
  He pulled the remains of the combine into position at the quarry and set up the feeder conveyer with its screener deck mounted to the top of the combine. Ohe ran a drive belt from a pulley on the jackshaft that previously powered the cylinder to the screener.
  A second jackshaft runs the stacking conveyer for screened sand and gravel, while the pulley that ran the feeder house now runs the oversize rock conveyor.
  The feeder conveyor was the only one too far away to be powered by belts off the combine. Here, too, Ohe took advantage of the tractor. He mounted a hydraulic motor on the feeder conveyor and ran hoses to the tractor.
  “I didn’t even have to buy new belts,” says Ohe. “I just set up the conveyors to match the belts I had. Using the combine, I knew I could just go to my local IH dealer if I needed replacement parts.”
  Ohe says the old conveyers cost him only $350. The combine was free, as it hadn’t been used in years, and a friend gave it to him. Best of all, the system worked better than a standard feeder conveyor and screener unit would.
  “The screener unit had been attached to the end of the feeder conveyor,” says Ohe. “That way you could only do a load at a time. With the three conveyors, I can stockpile 10 to 15 loads without stopping.”
