Section 3: Adjustments
Blade Pitch
Blade pitch can be adjusted by lengthening or shortening
tractor’s top center 3-Point link. Increasing blade pitch will
increase blade 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 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
WARNING
!
To avoid serious injury or death:
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
Manual Offset Adjustment
Refer to Figure 2-6 on page 17:
The blade offset has 9 adjustments up to 30" left or right.
(center position, 4 positions right, and 4 positions left)
1. Manually adjust blade offset by removing hitch
pin (#5) and moving inner link (#1) to a different hole
position.
2. Replace hitch pin and secure with hair pin
cotter (#6).
Hydraulic Offset Adjustment
Refer to Figure 2-1 on page 14:

The blade can be offset hydraulically by as much as 30"
to the right or left with offset cylinder. Operate tractor
control lever to change blade offset.
1. If offset cylinder is attached to selector valve, make
certain valve lever is set to operate that cylinder.
2. Operate tractor control lever to change blade offset
by as much as 30" right or left.
Blade Angle and Reversing
WARNING
!
To avoid serious injury or death:
•
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
Manual Angle Adjustment
Refer to Figure 2-6 on page 17:
There are 9 blade angle positions in 10 degree
increments. (center position, 4 clockwise positions, and
4 counterclockwise positions)
1. Adjust blade angle by removing hitch pin (#5) and
moving inner link (#1) to a different hole position.
2. Replace hitch pin and secure with hair pin
cotter (#6).
3. The blade may also be rotated around 180 degrees.
a. Disconnect angling link from blade turntable lug.
b. Rotate Rear Blade clockwise 180 degrees.
c. Reconnect angling link to turntable lug.
Hydraulic Angle Adjustment
Refer to Figure 2-2 on page 15:

Adjust blade angle with angling cylinder by as much as
50 degrees clockwise and counterclockwise. Operate
tractor control lever to change blade angle.
1. If angling cylinder is attached to selector valve, make
certain the valve lever is set to operate that cylinder.
2. Operate tractor control lever to change blade angle
by as much as 50 degrees forward or backward.
3. The blade may also be rotated 180 degrees.
a. Disconnect angle cylinder from blade turntable
lug.
b. Rotate Rear Blade clockwise 180 degrees.
c. Reconnect angle cylinder to turntable lug.
IMPORTANT:
Make sure angling link is installed
