Blade Adjustments
There are 5 adjustments that can be made to the blade.
They are blade pitch, angling, reversing, tilting, and
offsetting. Most are done manually, Blade angling can be
done hydraulically if Hydraulic Angling Kit is installed.
WARNING
!
To avoid serious injury or death:
•
Do not come in contact with turntables or stick objects into
the turntable holes while adjusting the unit’s angle. Doing
so can pinch or shear body extremities and objects.
• 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
implement and/or tractor.
Blade Tilting
Refer to Figure 3-1:
WARNING
!
To avoid serious injury or death:
Do not tilt blade when backfilling. Tilting the blade to backfill
can result in lost of control and damage the unit.
Five holes are provided for tilting end of blade up or down
by as much as 15 degrees in 7 1/2 degree increments.
1. The Rear Blade must be hitched to a tractor and
raised off the ground high enough to make this
adjustment.
2. Rotate handle of bent pin (#2) up and pull pin out.
3. Tilt blade to desired angle and reinsert bent pin.
Rotate handle down to secure bent pin in place.

make the following adjustments.
NOTE: Make certain hitch pin (#1) in Figure 3-2 is
removed before operating hydraulic cylinder.

Blade Pitch
Refer to Figure 3-3 on page 14:
Blade pitch can be adjusted by lengthening or shortening
the tractor’s top center 3-point link. Increasing blade pitch
will increase blade’s ability to dig.
Lengthen center 3-point link to increase blade pitch when
grading while traveling forward. Shorten center
3-point link to decrease blade pitch.
The opposite is true if backfilling. Shorten center 3-point
link to increase blade pitch and lengthen center 3-point
link to decrease blade pitch. To help protect the Rear
Blade from becoming damage while backfilling, lengthen
tractor’s center 3-point link until the blade moves across
the top of the ground without forcing itself into the soil.
Manual Angling
Refer to Figure 3-2:
Seven holes are provided for angling the blade up to 45
o
when traveling forward.
1. Remove hairpin cotter (#2) from hitch pin (#1) and
pull hitch pin from mainframe hole.
2. Rotate blade to desired angle and reinsert hitch
pin (#1) into hole in mainframe and hole in turntable.
3. Secure hitch pin (#1) with hairpin cotter (#2).
Manual Reversing
Refer to Figure 3-2:
Three holes are provided for angling the blade up to 30
o
when traveling in reverse.
1. Pull hairpin cotter (#2) from hitch pin (#1) and hitch
pin from mainframe hole.
2. Rotate blade 180
o
and reinsert hitch pin (#1).
3. Secure hitch pin (#1) with hairpin cotter (#2).
