Place the tractor rockshaft control in “position con- trol” (non-floating) for attaching and detaching the rear mounted blade. “Draft control” or “position con- trol” can be used while operating. Back the tractor until the ends of the lift arms can be attached to the lift pins on the implement. NOTE: Hitch pins can be mounted extending toward the outside or center of the implement to fit different tractor lift arms. Secure the lift arms to the pins. (Figure 1) Attach the center link to the top of the mast and adjust so that the blade frame will be level in the operating position. DETACHING FROM TRACTOR Lower the blade to the ground with rockshaft control in position control. Remove top link from mast, dis- connect hitch arms from bottom pins and pull tractor away from blade. 6 Figure 3 Scarifier Shank Adjustment Pin OPERATION Level the box blade from side to side and front to rear using adjustments on the tractor’s 3-point lift. To adjust the scarifier shanks, first remove the pins which hold the shanks in place. Slide the shanks up or down to desired position and replace the pins. (Figure 3) SECTION II - MAINTENANCEKeepallbladenutsandboltstightenedto175ft.lbs. Blades can be reversed to use opposite cutting edgewhen needed. (Figure 2) ReplaceableTipsReversible Blade The scarifiers should be adjusted to the lowest posi- tion to penetrate and break up the surface when moving large volumes of soil. When leveling, the tips should be positioned to barely chip the surface, and when smoothing, the tips should completely clear the ground. Care should be exercised during use of the box blade to prevent hanging the scarifier points or the blades on immovable objects or otherwise use the implement under conditions beyond its designed capacity. CAUTION WHEN EQUIPMENT IS TRANSPORTED, USE NECESSARY DEVICES REQUIRED BY LOCAL REGULATIONS FOR ADEQUATE WARNING TO OPERATORS OF OTHER VEHICLES. CAUTION LOWER THE BLADE AS MUCH AS POS- SIBLE AND SECURELY SUPPORT BEFORE MAKING ANY ADJUSTMENT. Inspect your box scraper periodically and replace any worn or broken parts in order to have it ready for use when needed. Worn scarifier tips may be replaced by grinding or torching off the old tips and welding on replacements. (Figure 3) Store the box blade out of the weather when it is not in use. This helps prevent rusting of the blades and other components. 7 SAFETY DECALS To promote safe operation, Bush Hog supplies safety decals on all products manufactured. Because damages can occur to safety decals either through shipment, use or reconditioning, Bush Hog will, upon request, provide safety decals for any of our products in the field at no charge.
