Open and Closed Center Hydraulic Systems
•
Most late model tractors use a Closed Center hydraulic system with a variable displacement pump which
only pumps oil as required. This system is commonly CCLS (Closed Center Load Sensing), also known
as PFC (Pressure and Flow Compensated). The ball valve on the spreader should be closed.
•
Other tractors may have an Open Center hydraulic system with a fixed displacement pump which pumps oil
continuously. This type of system typically does not have adjustable flow control from the tractor cab. The
Excess Flow (EF or EX) port on the spreader valve allows the excess flow to return to the tractor. The ball
valve on the spreader should be open.
•
Check with your tractor dealer if you are not sure of which system you have equipped.
TRACTOR HOOKUP
1. Check that area is clear,
SLOWLY
back up tractor to spreader and line up draw pin holes.
2. Shift tractor to neutral or park and set the brakes.
3. Hook the spreader hitch to the tractor drawbar with Ø1-1/2
” secured hitch pin.
4. Raise the jack off the ground. Remove the jack hub pin and rotate the jack to the horizontal position or move to
secondary storage location and secure with the pin.
5. Connect the PTO drive shaft to the tractor PTO output shaft and be sure it is locked to the tractor PTO shaft.
6. Connect the 7-Pin electrical plug for the lights to the receptacle on the tractor.
7.
Run the “twist hose” (if equipped) for controlling apron speed to the tractor cab where it can be operated.
8. Connect the hydraulic hoses from the spreader to paired remote ports on the tractor.
Apron Drive
– (2x) 8M3K Ø1/2” ID Hoses Hydraulic Gate – (2x) 6M3K Ø3/8” ID Hoses
NOTICE!
The spreader apron circuit has a check valve so that the apron may not be operated in the wrong
direction. If the hoses are reversed, the apron will not operate and the hoses should be switched.
TRANSPORTING
GENERAL
While towing the spreader, check for traffic constantly. Be sure you
c
an see that no one is attempting to pass you
and that all traffic is sufficiently clear from you before making any turns.
Operating speed is dictated by the terrain over which you are traveling. Always use caution. Avoid traveling on
slopes or hills that are unsafe. Also beware of slippery conditions such as traveling over areas previously spread
with manure. If possible, avoid spreading over areas where manure has been previously applied.
If you will travel on public roadways and it is legal to do so, you must know all rules governing such operation. This
will include lighting and brake requirements in addition to traffic rules. You may also be required to install a safety
chain on the spreader.
CAUTION
REGULARLY CLEAN OFF THE REFLECTIVE TAPE
AT THE REAR AND SIDES OF THE SPREADER
WHEN TRANSPORTING IT ON THE HIGHWAY.
WARNING
DO NOT TOW AT SPEEDS GREATER THAN 20
MPH. FAILURE TO HEED MAY RESULT IN
SERIOUS PERSONAL INJURY OR DEATH.
