When Pat Burrington needed a small box scraper to level his road and driveway, he built his own 6-ft. wide, 3-pt. mounted “quick-adjust” box scraper for only about $700. He uses his Allis Chalmers WD-45 tractor to pull it.”
    He mounted a 4,000-lb. trailer screw jack equipped with a hand-operated crank on the scraper frame. The bottom of the jack is bolted to a horizontal steel tube that raises and lowers the scraper’s ripper teeth. To raise or lower the teeth, Burrington just reaches back from the tractor seat and turns the crank.
    “It’s the lazy man’s way to adjust the ripper teeth depth on a box scraper,” says Burrington, who operates a local fabrication shop. “The quick-adjust feature is something I haven’t seen on any commercial box scraper. Most small box scrapers come with individual ripper teeth that pin into place, so you have to get off the tractor and pull the pin on each one to adjust the ripper up or down. If the hole spacings are 2 in. apart, you have to live with that amount of pre-determined adjustment.
    “With my design I never have to get off the tractor, and I can adjust the teeth depth incrementally. I can set all the teeth to dig deep on the first pass and then raise them on the second pass to level the loosened ground in a matter of seconds and never leave the tractor seat. Or I can raise the teeth completely out of the ground and use the scraper to fill pot holes.”
    Another advantage, says Burrington, is that the scraper is built “simple” without needing hydraulics to adjust the teeth depth, which makes it easy to operate. “I added more than 100 lbs. to the scraper with the jack, the pivot arm and miscellaneous hardware, which helps it dig better since I don’t have 2-way hydraulics on my old tractor’s 3-pt. hitch.”
       The box scraper’s body is made from 3/16-in. steel plate. The frame is made from 2 by 4-in. rectangular tubing. The wear bar is an old grader blade; the pivot arm is made from square tubing and flat bar; and the teeth are built from 1/2-in. thick abrasion resistant AR400steel. “I cut out all the teeth on my waterjet cutting table,” notes Burrington.
