after they are installed.

Storage
Clean, inspect, service, and make necessary repairs to
the Retractable Box Scraper when parking it for long
periods and when parking it at the end of a working
season. This will help ensure that the scraper is ready for
field use next time you hook-up to it.
1. Clean off loose and compacted dirt that may have
accumulated on the scraper and cutting blades and
then wash surfaces thoroughly with a garden hose.
2. Check shank bars and plow bolts for wear and
replace if necessary. For additional instructions, see
“Cutting Blades” on this page.
3. Inspect Retractable Box Scraper for loose,
damaged, or worn parts. Adjust and tighten loose
parts. When needed, replace parts with genuine
Land Parts only.
4. Repaint parts where paint is worn or scratched to
prevent rust. Ask your dealer for Land Pride aerosol
touch-up paint. They are also available in touch-up
bottles with brush, quarts, and gallon sizes by adding
TU, QT, or GL to the end of the aerosol part number.
5. Replace all damaged or missing decals.
6. Lubricate as noted in “Lubrication” on page 13.
7. A light coat of oil or grease may be applied to the
shank bar and to any exposed hydraulic cylinder rods
to minimize oxidation.
8. Store scraper on a level surface in a clean, dry place.
Inside storage will reduce maintenance and make for
a longer scraper life.

Section 4: Maintenance & Lubrication
Maintenance
Proper servicing and adjustment is the key to the long life
of any implement. With careful inspection and routine
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
Land Pride dealer. Add grease to the zerks per
Lubrication Schedule on page 13.
The parts on your Retractable Box Scraper have been
specially designed and should only be replaced with
genuine Land Pride parts. Do not alter the scraper in a
way 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
maintenances will go a long way to prevent occurrence of
control valve and hydraulic cylinder problems.
Cutting Blades
Refer to Figure 4-1:
The front and rear cutting blades (#4) have two cutting
edges. Replace cutting blades when both edges are
worn out.
1. Unbolt cutting blade (#4) and turn it over when its
bottom cutting edge wears out.
2. Inspect 5/8" -11 x 1 1/4" GR5 plow bolts (#1),
5/8"-11 x 2" GR5 plow bolts (#2), and hex flange lock
nuts (#3) for wear. Replace as needed.
3. Reattach blade and tighten to required torque.
