Tire Cutter Runs Off Tractor Hydraulics
The tire cutter is powered off tractor hydraulics and consists of a steel table equipped with a 7 1/4-in. dia. skil saw blade. The blade is chain-driven by a hydraulic motor. A 6-in. dia. slotted press wheel slides back and forth inside the tire, controlled by a hydraulic cylinder. A dual spool valve and control levers for the motor and cylinder mount at one end of the table.
To cut a tire, Lindstrom places it on top of the table and uses the press wheel to push the tire against the blade, which rotates the tire as it cuts through the center of the tread. "The saw blade grabs the tire and pulls it into the slotted press wheel in a kind of shearing action. I can cut up 150 to 200 tires per hour. I've also done a few jobs for neighbors, charging 40 cents per tire. The machine can handle most car or truck tires, but it is not designed to handle semi tires.
"The total cost to build was less than $200. I salvaged the hydraulic motor from a junked auger and the hydraulic cylinder from a manure spreader. I had the blade and the shaft that supports it was made at a machine shop."
