General Maintenance Information
Proper servicing and adjustment is the key to the long life of any implement. With careful inspections and
routing maintenance, you can avoid costly downtime and repair.
Check all bolts after using the unit for several hours to be sure they are tight. Replace any worn, damaged or
illegible safety labels by obtaining new labels from your Bush Hog dealer.
The parts on your Pull Type Drag Scraper have been especially designed and should only be replaced with
genuine Bush Hog parts. Do not alter the scraper in anyway which will adversely affect its performance.
Tractor Maintenance
One of the most important things you can do to prevent hydraulic system problems is ensure that your tractor’s
reservoir remains free of dirt and contamination. Use a clean cloth to wipe hose ends before attaching them to
your tractor. Replace your tractor’s hydraulic filter element at the prescribed intervals. These simple
maintenance will go a long way to prevent occurrence of control valve and hydraulic cylinder problems.
Cutting Edge
Always secure scraper in the up position with solid supports before servicing the underside.
Never work under equipment supported by hydraulics. Hydraulics can drop equipment if
controls are actuated or if hydraulic lines burst. Either situation can drop the scraper
instantly even when power to the hydraulics is shut off.
Always inspect cutting blade (#1) before each use. Make certain it is properly installed and in good working
condition.
1. Unbolt cutting blade (#1) and turn it over
when the bottom cutting edge is worn out.
Replace blade when the top and bottom
edges are worn out.
2. Inspect 5/8”-11 x 1-3/4” GR5 plow bolts (#2)
and hex nuts (#3) for wear. Replace if worn
out.
3. Reattach blade (#1) with plow bolts (#2) and
hex nuts (#3). Tighten nuts to the correct
torque. (See Torque Value Chart in
Maintenance Section).
