CONVERTING A SPREADER FROM
CLOSED CENTER TO OPEN CENTER
WARNING
ESCAPING HYDRAULIC FLUID UNDER PRESSURE
CAN PENETRATE THE SKIN AND CAUSE SERIOUS
INJURY. RELIEVE ALL PRESSURE FROM THE
HYDRAULIC SYSTEM BEFORE CONNECTING OR
DISCONNECTING THE LINES OR MAKING
REPAIRS. CHECK ALL HOSES AND FITTINGS
BEFORE START-UP AND PERIODICALLY DURING
OPERATION.
Most late model tractors use a closed center hydraulic
system which only pumps oil as required. Some other
tractors may have an open center system which
pumps oil continuously, in which case provision must
be made to allow excess flow back to the tractor reser
-
voir. This is done by converting your spreader to open
center as instructed in the following.
If you are not sure of your system, contact your tractor
dealer.
