Backfill and Backgrade
BACKFILLING -
To reduce the risk of a
trench caving in, keep
tractor tires back from
the trench, the same
distance as the depth
of the trench.
Approach pile with level bucket.
Operate at right angles to trench
taking as much material
as tractor and loader
can handle.
BACKGRADING -
Backgrade with heel of bucket only, or
use optional BACKDRAG BLADE. Place control lever in
float position so bucket follows the contour of the surface.
Angle the bucket slightly, move forward slowly and lower
the bucket to start the cut.
When the bucket has penetrated the material, level the
bucket and move forward until the bucket is full. Use
the bucket control lever to control the
depth of the cut. Use FLOAT to
reduce down pressure and
wear on the cutting edge
when scraping.
Make additional passes until desired depth is reached.
During each pass, use only the
bucket cylinder control while at
working depth to control the
bucket angle to maintain
a precise cut.
Peeling and Scraping
While working on a hard surface, level the bucket and
place control lever in float detent. This will allow the
bucket to “float” and follow the surface contour.
To place control lever in float, lower bucket or attachment
and push control lever fully forward into detent. The
control lever will remain in detent until manually pulled
back out of detent to deactivate float. Using float will also
prevent surface gouging and the mixing of the surface
material with the stockpile material.
Operating With Float Control
TIP
Pushing with the material in the bucket will save time.
To prevent electrocution:
•
NEVER
let equipment near or
contact power lines.
• Electrocution can occur with-
out direct contact.
•
ALWAYS
check clearance before raising equipment.
•
DO NOT
leave operator’s seat if any part of
equipment contacts power lines or cables.
•
ALWAYS
have local utilities
locate and mark underground
wires, cables, pipelines and
other hazards before digging.
ELECTROCUTION
HAZARD.
DANGER
Example: If the trench is 3
feet deep (B), the tractor tires
must stay 3 feet (A) from the trench.
• Backfilling and backgrading with the bucket dumped
may damage the bucket control cylinders.
• If bucket hits a solid object while INCORRECTLY
positioned, you will damage your cylinders, linkage
and/or cutting edge.
• Backfill and backgrade with the bucket level.
