6.2. UNLOADING
DANGER: MAKE CERTAIN ALL PERSONNEL ARE CLEAR OF THE SPREADER AND THE
ROTATING SPINNERS BEFORE APPLYING POWER. FAILURE TO HEED MAY RESULT IN SERIOUS
PERSONAL INJURY OR DEATH.
When you are ready to begin spreading application on the field, open the hydraulic flow control rear gate and
slowly engage the tractor PTO clutch. This can be done while traveling forward to avoid a heavier application of
liquid manure at the edge of the field than desired.
For liquid and semi-liquid manure, the application rate can be
controlled by the amount the flow control rear gate is opened.
The gate indicator on the front of the box will provide a ready
reference for the amount of opening. For solid manure (dry,
pen-packed or manure containing long straw or hay) the flow
control rear gate MUST be completely open since this
material is not free flowing.
The rear spinners have been designed and tested to provide
the best spread pattern for most liquids and semi solid
manure. However, the pattern will vary for each specific
condition. The factors that contribute most to differing
patterns will be moisture content and the amount and length
of bedding material. For most typical conditions, the spread
pattern should be uniform and about 15 ft. wide. When this is
the case, plan your spreading patterns so you do not have to travel over previously spread manure which will be
slippery, resulting in poor traction. Traction on wet grass is also poor. When the resulting pattern may require
that you overlap during spreading, use precautions on slopes and hills where you could experience a loss of
traction by traveling over ground with previously spread manure.
NOTE: Further control of the application rate is possible by the relationship of tractor engine speed to ground
speed (transmission gear selection). For optimum, trouble-free performance it is recommended to operate at or
near engine PTO speed.
When the spreader is empty, idle the tractor and stop the PTO. Close the flow control rear gate.
NOTE: Failure to idle the tractor before disengaging the PTO will
cause roller chain over-running and damage to the chain tighteners.
NOTE: Maximum life of the PTO shaft universal joints will result if
you stop the PTO while making turns at the end of the field.
NOTICE: DO NOT EXCEED THE MAXIMUM 80° TURNING
ANGLE ON THE CONSTANT VELOCITY PTO DRIVELINE.
EXCEEDING THE TURNING ANGLE WILL DAMAGE THE
CONSTANT VELOCITY “CENTER HOUSING” AND WILL EXERT
EXCESSIVE PRESSURES ON THE PTO INPUT CENTER SHAFT
AND RELATED BEARINGS.
