Rear Blade Functions
WARNING
!
To avoid serious injury or death:
Never operate hydraulic cylinder(s) with blade in the ground
or under load. Improper use can result in loss of control and
damage the Rear Blade. Always lift blade up before operating
hydraulic cylinder(s).
Grading
Place grade stakes if you intend to develop a specific
grade or soil level. Pivot moldboard to the desired angle,
lower blade to the ground and set the tractor’s draft-link
height control to the desired position. Proceed forward at
a speed of no more than 2 to 4 mph. The blade should
immediately begin shaving the surface. A blade full of
material can be raised slightly so that the material can
flow out evenly under the blade to effectively shave off
high spots and fill in potholes or depressions. Loose soil
can be smoothed out by pushing the soil with the back of
the moldboard while backing-up.
If single or dual gauge wheels are included, set tractor’s
draft-link height control to the maximum preferred cutting
depth. Raise and lower blade with the gauge wheel(s).
Edge work
Material that is close to fences, buildings, and other
obstructions can be graded by offsetting the moldboard
to the right or left beyond the tractor tire. Always make
certain the end of the blade is offset far enough to be
visible to the operator. Always keep a safe distance away
from obstructions, drive slowly when passing by them
and stay clear of them when turning. Always be aware
that the blade will make a wide swinging pattern in a turn
and always be ready to stop immediately to keep from
hitting an obstruction. Never hit an obstruction as this can
damage the blade and/or obstruction.
Ditch Work
The Rear Blade is good for making V-type ditches. Tilt
one end of moldboard down to desired ditching angle.
Offset that end to be in line with tractor’s rear tire and
pivot opposite end of moldboard back. The combined
angles, pivot, and offset, should be between 45
o
and 60
o
.
Operate tractor at slow speeds when cleaning a ditch or
removing snow. Be careful not to hit hidden solid objects
that can damage the Rear Blade. Always be ready to stop
immediately. Remember, the lighter the blade load, the
easier it is for the tractor to damage the blade.
Fill ditches by offsetting the blade beyond the tractor
wheel to keep the tractor out of the ditch. Angle the blade
to move the dirt toward and into the ditch while traveling
forward. Set blade depth as needed (see “Grading”
instructions on this page when setting blade depth).
IMPORTANT: The warranty shall not apply to
damage caused by misuse, abuse, or contact with
obstructions.
Backfilling
Backfilling is a process where the operator turns the
blade around 180
o
and pushes product while backing-up.
Be careful not to overstress the blade while backfilling as
load forces on the blade and frame increase when
backing up. To help protect the blade from damage,
lengthen tractor’s top center link until the blade will move
across the top of the ground without forcing itself into the
ground.
Adjust offset to be straight behind the tractor and set
blade angle at 90
o
(perpendicular to the Mainframe).
Keep load in the center of the blade and not on the end of
the blade. Don’t ram 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.
Unhook Rear Blade
WARNING
!
To avoid serious injury or death:
When using the park stand, make sure it is fully down with wire
retaining pin fully inserted and wire retainer over end of pin.
If not, the implement could fall.
Unhook 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.
6. Unhook couplings from the tractor and store in
coupling storage slots to keep couplings out of the
dirt. See “Figure 1-2” on page 11 for location of
coupling storage slots.
7. If necessary, adjust length of upper center 3-Point
link until the hitch pin can be removed from the hitch
frame.
8. Remove hitch pins from the lower 3-Point arms at the
hitch frame.
9. Reinstall hitch pins, linchpins and hairpin cotters in
the Rear Blade hitch frame for storage.
10. Refer to
“Long-Term Storage”
instructions on page
25 when storing the Rear Blade for a long time.
