Safety First
WARNING
!
To avoid serious injury or death:
•
Do not allow anyone to go near the blade while grading and
operating the controls. A person can be crushed by the unit.
•
Avoid injury from a falling blade. Always check to make
sure all hardware is secured before adjusting the blade.
•
Never fully extend or retract hydraulic cylinder(s) without
first checking to make sure the implement does not make
contact with tractor tires. Extending implement into the
tractor tires can result in loss of control and damage to the
Blade Pitch
Blade pitch can be adjusted by lengthening or shortening
the tractor’s top center 3-Point link. Increasing blade pitch
will increase the blades digging ability.
Lengthen link to increase blade pitch when grading while
traveling forward. Shorten link to decrease blade pitch.
The opposite is true if backfilling. Shorten link to increase
blade pitch and lengthen link to decrease blade pitch. To
help protect 3-Way Rear Blade from damage while
backfilling, lengthen tractor’s center top link until blade
will move across top of ground without forcing itself into
the soil.
Blade Offset
Manual Offset Adjustment
Refer to Figure 2-4 on page 12:
The blade offset has 15 adjustments up to 33" left or right.
(Center position, 7 positions right, and 7 positions left.)
1.
Read and follow
offsetting the blade.
2. Manually adjust blade offset by removing hitch
pin (#2) and moving outer link (#3) to a different hole
position.
3. Replace hitch pin and secure with hair pin
cotter (#5).
Hydraulic Offset Adjustment
Refer to Figure 2-1 on page 10:
The blade can be offset hydraulically by as much as 33"
to the right or left with offset cylinder.
1.
Read and follow
offsetting the blade.
2. If offset cylinder is attached to the selector valve,
make certain the valve lever is set to operate that
cylinder.
3. Operate tractor control lever to change blade offset
by as much as 33" right or left.
Blade Angle and Reversing
Manual Angle Adjustment
Refer to Figure 2-4 on page 12:
There are 15 blade angle positions; up to 45 degrees
right or left. (Center, 7 clockwise, and 7 counterclockwise
positions.)
1.
Read and follow
offsetting the blade.
2. Adjust blade angle by removing hitch pin (#2) and
moving outer link (#3) to a different hole position.
3. Replace hitch pin and secure with hair pin
cotter (#5).
4. The blade may also be rotated around 180 degrees.
a. Disconnect angling link from blade turntable lug.
b. Rotate blade clockwise 180 degrees.
c. Reconnect angling link to turntable lug.
Hydraulic Angle Adjustment
Refer to Figure 2-2 on page 10:
Adjust blade angle with angling cylinder by as much as
45 degrees clockwise and counterclockwise.
1.
Read and follow
offsetting the blade.
2. If the angling cylinder is attached to the selector
valve, make certain the valve lever is set to operate
that cylinder.
3. Operate tractor control lever to change blade angle
by as much as 45 degrees forward or backward.
4. The blade may also be rotated 180 degrees.
a. Disconnect angle cylinder from blade turntable
lug.
b. Rotate 3-Way Rear Blade clockwise 180 degrees.
c. Reconnect angle cylinder to turntable lug.
IMPORTANT:
Make sure angling link is installed
correctly before using the blade. If not the blade and/
or angle cylinder can be damaged.
IMPORTANT:
Make sure angle cylinder is installed
correctly before using the blade. If not, the blade
