Heavy-Duty Rock Roller

Heavy-Duty Rock Roller MISCELLANEOUS EQUIPMENT Miscellaneous 19-1-36 Rocks in our hay fields cause real head-aches when we're swathing. It's impossible to pick all of them up, so I made a heavy-duty "Rock Roller" for pushing them into the ground. It's made out of a 36-in: dia. section of road culvert 12 ft. long and filled with 3 cu. yds. of concrete. A 3-in. dia. pipe runs through the center of the culvert section. Stub axles off a 914 International combine fit right inside the pipe. Axles mount in two 1/2 in. thick steel plates, 18 in. wide by 20 in. long, bolted to the sides of the frame of an old chisel plow. We pull the "Rock Roller" with a 1070 Case tractor, but any tractor rated at over 100 hp. would probably do. You have to slow down on corners because the weight of the roller - 5 tons - will push you around. Otherwise, we can run at field speeds of between 8 and 10 mph. When the ground is moist enough, we're able to bury all the rocks up to 6 in. in dia. I invested only $1,000 in the device. Grant Gulleson, R.R., Box 17, Rutland, N. Dak. 58067.
