NOTE: Heaped loads have significantly higher
capacities resulting in increased weight and higher
center of gravity, requiring extra precaution during
operation.
Tractor Hookup
FIGURE 2. TRACTOR HOOKUP
1. Hook the spreader hitch to the tractor drawbar
with secured hitch pin conforming to the pin hole
size in the spreader hitch.
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.
3. Connect the PTO drive shaft to the tractor PTO
output shaft and be sure it is locked to the tractor
shaft.
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.
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 convenience. The flow control lever has
a tension screw adjustment to regulate force to
retain settings, Figure 3.
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
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 through the return hose back to the
tractor reservoir by closing the ball valve on the
flow control. 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 illustrated on Figure 3. If you have a
Closed Center, close the ball valve shown on
Figure 3.
