ADJUSTING TOP LINK
The box scraper is leveled by adjusting the length of the
tractor's top link.
●
Shortening the top link will deepen the scarifier tooth
penetration.
●
Lengthening the top link will provide better scraping
and leveling action.
Experience will allow the operator to determine the best
setting for the application being done.
NOTICE
This unit is intended to move materials such as dirt,
sand, gravel, etc. Unintended use may damage the
box scraper.
SCARIFYING
1.
Place the scarifier shanks in position with the points
facing toward the tractor.
2.
Lock into position with the lock pins provided. The
lower shank position provides the greatest ground
penetration.
3.
Lower the box scraper and drive the tractor ahead to
begin the scarifying operation.
4.
Adjust the depth of the scarifier by tilting the unit with
the tractor top link. Shortening the top link will
provide deeper and more aggressive operation.
SCRAPING
1.
Raise or remove the scarifier shanks. Lower the box
scraper and drive forward to move material.
2.
Adjust the depth of the scraper by tilting the unit with
the tractor top link.
Shortening the top link when scraping will transfer
more weight on the front of the scraper and will raise
the cutting scraper to provide a more shallow cut.
NOTE:
When the top link is adjusted properly, the
bowl of the scraper should fill easily and material can
be pulled to a desired location.
3.
To change the level of the scraper, shorten or
lengthen the tractor lift arm tilt link to provide the
correct slope.
4.
Spread material by gradually raising the box scraper
as the tractor moves forward.
NOTE:
Top link adjustment for loose or previously
scarified material will differ from adjustment for hard
or compacted material.
BACKFILLING
1.
Raise or remove scarifier shanks.
2.
Lower the scraper to the ground and back up into the
fill material.
3.
Shorten the top link to raise the cutting scraper and
control how much the scraper digs in.
LEVELING
1.
Raise or remove scarifier shanks.
2.
Shorten the top link so the cutting edge clears the
ground.
3.
Drive forward with the box scraper in this position
and loose material will be leveled.
