Section 3: Adjustments
Gauge Wheel Depth
Refer to Figure 3-1:
Move gauge wheels up or down to set working depth. Do
not use skid steer to control roller height.
1.
Remove linchpin (#5) and washer (#4).
2.
Reposition spacers (#3) on spindle (#1) as follows:
To Increase Working Depth
Remove desired number of lower spacers (#3) from
below the support arm and add to gauge wheel
spindle (#1) above the support arm.
To Decrease Working Depth
Pull desired number of upper spacers (#3) from
above the support arm and add to notch (#2) below
the support arm.
3.
Replace washer (#4) and secure with linchpins (#5).
4.
Repeat above steps 1-3 for the other side.
Angle/Float Hitch (Optional)
Refer to Figure 3-2:
1.
Shut skid steer down properly before dismounting.
Refer to
“Skid Steer Shutdown Procedure”
20.
2.
Place two solid support blocks on the ground in front
of the rake hitch plate. Support blocks must be strong
enough and high enough to support the roller and
gauge wheels slightly off the ground with the rake
hitch plate resting on the blocks.
3.
Return to the skid steer. Start skid steer and raise
Powered Rake up.
4.
Drive forward until rake hitch plate is above support
blocks (#4). Lower rake until its hitch plate is resting
on the support blocks.
5.
With hitch plate resting on support blocks (#4), shut
skid steer down properly before dismounting.
6.
Remove hairpin cotter (#3) from hitch pin (#2) on the
right-hand side of the hitch plate.
7.
Place pin (#2) in holes “A” to unlock parallel arms and
in holes “B” to lock parallel arms. Secure pin (#2) with
hairpin cotter (#3).
8.
Repeat steps 6 & 7 for the left-hand side.
Material Control Blades
Refer to Figure 3-3:
Adjust gap opening of front material control blade (#2) or
rear material control blade (#3) as follows:
NOTE:
The gauge wheel on the chaincase side
should be down approximately 1" more than the non-
drive side to compensate for extra chaincase weight.
NOTE:
To remove lower spacers (#3) from gage
wheel spindle (#1), rotate open end of spacer to
align with notch (#2) and pull spacer from spindle.

Float Hitch Adjustments
Figure 3-2
Front & Rear Material Control Blade Adjustments
Figure 3-3
1.
Loosening hex flange nuts (#1) for front material
control blade (#2) or rear material control blade (#3).
2.
Slide material control blade up or down to increase or
decrease opening between blade and roller.
3.
Tighten hex flange nuts (#1) to the correct torque.
4.
If additional adjustment down is needed, move
bolts (#1) up to hole (#4).
