The DR PRO 48 in. Power Grader with Powered Remote is a tow-behind grader that attaches to most lawn tractors, utility tractors and ATVs. DR's PRO grader models offer the convenience of cabled remote control that lets you adjust your grading depth from your tow vehicle while you drive. 12 carbide-tipped grading teeth loosen hard-packed dirt and gravel to remove bumps and washboard, as well as fill in potholes. The rear leveling blade then spreads the loosened material evenly. You can easily add weight (standard masonry blocks) to the power grader's frame for more aggressive performance. Precise remote control lets you raise or lower the scarifying teeth from your towing vehicle with the touch of a button 12 tungsten-carbide scarifying teeth are 10x harder than steel - it's the same material used on mining equipment to chew through solid rock Powerful actuator provides a 4-in. stroke, raising the teeth from 4.5 in. above the surface (for travel and turning around) to 9/16 in. below the surface Steel box shields the actuator from the elements and kicked-up debris while using the tow-behind grader Solid 1/4-in. thick steel leveling blade Rechargeable battery is easily removed without tools for bringing indoors during the off-season and can be charged on or off the grader (charger included) DR PRO 48 Power Grader comes with pin hitch and ball hitch connectors for attachment to a lawn or garden tractor (14 HP and/or 400 lb. minimum).
