Effective Spread Width
Refer to Figure 7-2:
The spread pattern of the Pendulum Spreader takes the
shape of a pyramid. That is to say, the distribution is
heaviest directly behind the spreader and steadily
decreases the farther away the product is thrown. This
decreasing pattern is approximately equal on the left and
right side. To achieve an even amount of spreading over
the surface of the ground, the tractor and spreader
should travel parallel to the previous path at a distance
equal to 1/2 the overall spread width away from the first
path. This distance is known as the “Effective Spread
Width”. It is recommended that a GPS or markers be used
to control the path the tractor will travel.
Field Application
Refer to Figure 7-3:
1. Be sure hopper discharge rate is set and spreader is
at the application site before filling the hopper.
2. Start tractor #1 in a field corner at a distance equal to
(W/2) away from the field edge.
3. Maintain this half distance from the field edge as you
travel around the complete perimeter of the field.
4. When approaching starting point, turn tractor #2
when at distance (W/2) away from the first run and
travel parallel to the first run until the tractor #3 is at
distance (W/2) away from perimeter run.
5. Turn tractor and drive forward until at distance (W/2)
away from the last run and then turn the tractor #4
again to head back across the field.
6. Continue back parallel to the previous run until
tractor #5 is again at distance (W/2) away from
perimeter run.
7. Continue this back and forth pattern (2 to 3, 4 to 5,
6 to 7 etc.) until field plot has been covered.
Refer to Figure 7-2:
W = Overall Spread Width
W/2 = Effective Spread Width
(1/2 Of Overall Spread Width)
IMPORTANT:
Always disengage power take-off
before fully closing the discharge gate. Running
power take-off with gate closed can crush product,
break drive unit components and break or bend the
regulation bar.
IMPORTANT:
When manually opening discharge
gate, hold gate lever in the open position until power
take-off is running. Release grip of lever slowly.
NOTE:
Do not travel long distances with product in
the hopper or carry fertilizer bags stacked on top of
product in the hopper. Both situations will cause
fertilizer to compress and settle in the hopper
resulting in improper discharge rate.
