Backfilling
Backfilling is a process where the operator turns the
blade around 180
o
and pushes the product while
backing-up. Be careful not to overstress the Rear Blade
while backfilling as load forces on the blade and frame
increase when backing up. To help protect the Rear
Blade from damage, lengthen the tractor’s center top link
until the blade will move across the top of the ground
without forcing itself into the soil, adjust the offset to be
straight behind the tractor and set the blade angle at 90
o
(perpendicular to the Mainframe). Keep the load in the
center of the blade and not on the end of the blade. Don’t
ram a load with the blade and always operate at slow
speeds when backing-up. Be ready to stop immediately if
a solid object is hit. Removing snow while backing-up is
especially dangerous as snow can hide solid objects and
there is a tendency to drive too fast to get the snow
removal job done. High speeds multiply forces exerted
on the Rear Blade.
Un-Hooking the 3-Way Rear Blade
Un-hook 3-Way Rear Blade from the tractor as follows:
1.
Park on a level solid hard surface. Place tractor gear
selector in park and set park brake.
2.
Lower parking jack and secure with hitch pin.
3.
Lower blade and parking jack onto level ground or
onto blocks supporting the unit just above ground.
4.
Shut tractor engine off and remove key.
5.
If coupled to hydraulic cylinder(s), move hydraulic
control lever(s) back and forth several times to
reliever hydraulic pressure at the couplings and then
unhook couplings from the tractor and store on the
Rear Blade frame to keep couplings up out of the dirt.
6.
If necessary, adjust length of upper center 3-Point
link until the hitch pin can be removed from the hitch
frame.
7.
Remove hitch pins from the lower 3-Point arms at the
hitch frame.
8.
Reinstall hitch pins and linch pins in the Rear Blade
hitch frame for storage.
9.
Refer to “Storage” instructions on page 23 when
storing the Rear Blade for a long time.
Basic Operating Instructions
1.
Thoroughly Inspect the work area for buried utility
cables, pipelines, sprinkler heads, and any
unforeseen objects. Mark any potential hazards.
2.
Place grade stakes if you intend to develop a specific
grade or soil level.
3.
Adjust blade to the desired angle, tilt, and offset
position before lowering blade to the ground.
4.
Lower blade to the ground and proceed forward at a
speed of no more than 2 to 4 mph. The blade should
immediately begin shaving the soil surface.
5.
Set tractor’s draft-link height control lever to the
desired grade position. If blade is set at a 90 degree
angle to the direction of travel, it may be necessary to
raise the blade slightly so that dirt and gravel can flow
out evenly under the blade as it shaves off high spots
and fills in potholes or depressions.
General Operating Instructions
Once you have familiarized yourself with the Operator’s
Manual, completed the operations checklist, and
properly attached your Land Pride Rear Blade to your
tractor, you are now almost ready to begin work. The
RBT40 Series Rear Blades were designed and built by
Land Pride for category I or II three-point hitch and Quick
Hitch attachment to 60 to 100 hp tractors equipped with
remote hydraulic outlets and two wheeled drive
capability. Tractors with 4-wheeled drive capability may
also be used but additional care must be taken when
making tight turns with 4-wheel drive engaged and blade
in working position or pivot arm damage may occur. They
are ideal for snow removal as well as dirt leveling, finish
grading, and backfilling applications at feedlots, outdoor
arenas, building and construction sites, and
maintenance operations on farm and ranch lanes or
roadways. They are also excellent for soil contouring and
construction and maintenance of ditches and waterways.
Hopefully you have checked out your work site for any
buried utility cables, pipelines, sprinkler heads, or other
obstacles that you wouldn’t want to damage or
encounter. Grade stakes should now be in place if you
intend to develop a specific grade, elevation, soil contour,
or roadbed crown. A RBT40 Series Rear Blade’s primary
purpose is for grading or leveling of soil, gravel, or
aggregate in the warmer months or snow removal in the
colder months. These functions are best done at an
approximate 2 to 4mph ground speed. Becoming
proficient with a rear blade takes practice.
Tractor horsepower, your personal skill level, soil or
aggregate composition, moisture levels, and compaction
factors will all have a definite impact on how easily and
effectively you get the job done when you are in the dirt
working mode. Develop a plan to achieve your expected
results. Set the blade up at the proper angle or angles to
do the job. The hydraulic angling, tilt, and offset
capabilities of the RBT40 series will make these
adjustments easy utilizing the tractors remote hydraulic
