Blade Rotation Change
The SC40 cutter has the capability to switch blade
rotation directions. This will help utilize the dual sided
blades. Once the blades get dull you can switch blade
rotation and use the other side of the blades.
Refer to Figure 2-3:
1. Remove 5/16" hex nuts (#4), lock washers (#3) and
flat washers (#2). Remove U-bolt (#1).
2. Loosen nuts (#5 & 6). Do not take apart.
3. Loosen nuts (#7 & 8) and remove from hydraulic
fittings.
4. Rotate hose fittings (#9 & 10), along with the hoses
attached to them, 180 degrees so that fitting (#10)
attaches to hose nut (#8) and fitting (#9) attaches to
hose nut (#7).
5. Tighten nuts (#5, 6, 7 & 8)
6. Re-install U-bolt (#1) with flat washers (#2), lock
washers (#3) and nuts (#4). Tighten to correct torque.
7. Continue to step 8 if you have a pressure gauge
option. Otherwise blade rotation change is complete.
8. Remove cap (#11) from fitting (#13) as shown.
9. Remove pressure gauge hose from fitting (#12) and
attach the hose to fitting (#13).
10. Attach cap (#11) to fitting (#12).
11. Tighten the cap and pressure gauge hose.

Equipment Clearances
Visually inspect hydraulic hoses for possible pinch points
and length. Make any necessary adjustments before
putting equipment into service.
1. If necessary, have someone stand nearby that can
motion for the operator to stop if a problem develops
while checking for clearances.
2. With deck lowered to its minimum cutting height,
slowly tilt the hitch plate back raising the front of the
cutter while watching for interferences between skid
steer, skid steer wheels, and cutter. Make sure
hydraulic hoses are long enough and do not become
pinched through the full range of motion.
3. With hydraulic cylinders still retracted, slowly raise
cutter up while continuing to watch for interferences
between skid steer, skid steer wheels, and cutter
until height adjustment safety chain limit is reached.
4. Slowly tilt the hitch plate forward until the front of the
deck is touching the ground.
5. Tilt hitch plate back until the deck looks parallel with
the ground.
6. Slowly lower deck down while retracting hydraulic
cylinders on end of loader arms until deck is level and
resting on the ground.
7. Be sure to make any necessary corrections to the
hydraulic hoses before putting cutter into service.
