Connecting to Tractor (Cont’d)
Hydraulic Connections
Connect the spreader’s hydraulic hoses to the tractor’s
hydraulic system. Hydraulic hoses are marked with
corresponding “TANK” or “PRESSURE” decals.
Setting Tractor Hydraulics
For Clutch Disengage:
1. Valve should be set fully so cylinder extend/retract
time is 3 seconds.
IMPORTANT:
Clutch disengage cylinder is small – high
cylinder speed could damage cylinder
For Conveyor Drive and Spinners:
1. Make hydraulic hose connections.
2. Set hydraulics to continuous flow.
3. Determine if your tractor is equipped with an open-
center or closed-center hydraulic system.
NOTE:
For tractors equipped with an open-center
system, contact your dealer for an open-center
kit.

4. If the tractor has an
open-center system, pull the
red button (1) on the conveyor manifold out, and turn
to lock into place.
If the tractor has a
closed-center system, turn and
push the red button (1) on the controller in.
5. If the tractor is equipped with an open-center
system, set the tractor hydraulic flow to maximum.
6. Set the controller to Test mode.
7. Set the speed to 15 MPH.
8. Set the rate to 1,000 lbs.
9. Decrease the tractor hydraulic flow until the conveyor
slows. Then slightly increase tractor flow.
IMPORTANT:
This is done to reduce the amount of
bypass oil.
10. Exit the Test mode on the controller.
Connecting to Truck - Transporting
CAUTION:
Tow only with a truck or vehicle
capable of pulling the weight of the spreader
and its contents.
Adjust the spreader hitch so the spreader is as level
as possible. Connect to the truck hitch and install an
approved hitch pin for the load, securing hitch pin with
a safety locking pin. Connect the safety chains to the
truck.
IMPORTANT:
Make sure hydraulic hoses are secure
before transport.
IMPORTANT:
For PTO drive models, make sure PTO is
locked in the storage cradle and hydraulic
hoses are secure before transport.
