Operation 10
ADJUSTING TOP LINK
The box blade is leveled by adjusting the
length of the tractor’s top link.
• Shortening the top link will deepen the scari -
fier tooth penetration.
• Lengthening the top link will provide better
scraping and leveling action.
• Experience will allow the operator to deter -
mine the best setting for the application being
done.
SCARIFYING
1. Place the scarifier shanks in position with
the points facing toward the tractor.
2. Lock into position with the shank key pro-
vided. The lower shank position provides the
greatest ground penetration.
3. Lower the box blade 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 blade and drive forward to
move material.
2. Adjust the depth of the box blade by tilting
the unit with the tractor top link. Shortening
the top link when scraping will transfer more
weight on the front of the box blade and will
raise the cutting blade to provide a more shal-
low cut.
NOTE: When the top link is adjusted properly,
the bowl of the box blade should fill easily and
material can be pulled to a desired location.
3. To change the level of the box blade, short-
en
or lengthen the tractor lift arm tilt link to provide
the correct slope.
4. Spread material by gradually raising the box
blade as the tractor moves forward. 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 box blade to the ground and back
up into the fill material.
3. Shorten the top link to raise the cutting blade
and control how much the box blade 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 blade in this posi-
tion and loose material will be leveled.
STORAGE
• Block equipment securely for storage (see
Blocking Up Box Blade, page 11).
• Keep children and bystanders away from
storage area.
