2. Raise the jack off the ground. Remove the jack hub
pin and rotate the jack to horizontal storage position
and secure with the pin, Figure 2.
3. Connect the PTO drive shaft to the tractor PTO out-
put shaft and be sure it is locked to the tractor shaft.
4. If your spreader has an optional fine spread pan, tie
the rope control to a convenient place for operation
from the tractor seat.
Hydraulic Apron Drive
1. Connect the two hydraulic hoses for the apron drive
to a set of remote ports on the tractor. These are the
two hoses coming from the hydraulic flow control valve.
NOTE:
One of the lines going to the flow control has a
check valve in it so that the apron cannot be operated
in the wrong direction. This line must be connected to
the tractor return port. If the hoses are reversed, the
apron will not operate and the hoses should be
switched, see Figure 3 or Figure 4.
2. A “control hose” is connected to the flow control lever
with the opposite end having a bracket to hook at a
convenient location on the tractor for operator conven-
ience. The flow control lever has a tension screw ad-
justment to regulate force to retain settings, see Figure
3 or Figure 4.
3. Connect the two hydraulic hoses for the end gate to
a second pair of tractor remote ports.
Hydraulic System
1. Most late model tractors use a Closed Center hy-
draulic 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 through the return hose
back to the tractor reservoir. If you are not sure of your
system, contact your tractor dealer.
2. The spreader is normally shipped with the apron
drive flow control valve plumbed for Open Centers as il-
lustrated on Figure 3. If you have a Closed Center,
close the ball valve as shown on Figure 4.
