Setting Spinner Speed
Spinner speed is one of the most
important factors in achieving an accurate
spread pattern. The spinner speed can be
adjusted from the cab on most modern
tractors if equipped with closed centre
hydraulics, or from the front of the spreader
by using the flow control valve on open
centre hydraulic equipped tractors.
Refer page 18 for a guideline of
suggested spinner speeds for various
products. Every product will spread
differently depending on its bulk density,
granule size, variation in size and shape.
An incorrectly set spinner speed can
influence the spread pattern. By adjusting
the spinner speed by as little as 50rpm up or
down, it is possible to improve or alter
spread pattern.
Fig. G8 Speed control from spreader. Normally
set to fully open position for closed centre
equipped tractors.
For this reason it is suggested that
a spread pattern test be carried out if
maximum accuracy is required.
As a guide, if the spinner speed is too
high, there will be too much material directly
behind the spreader. If the spinner speed is
too slow, there will be too little material
directly behind the spreader.
Maximum spinner speed for the 675mm
spinners is 1050rpm.

Engaging the Jockey Wheel
To operate the feed chain the jockey
wheel must be in contact with the ground
wheel. A hydraulic cylinder is used to raise
and lower the gearbox/jockey wheel. Before
operating the spreader in the field, check that
the transport lock has been pulled out and
rotated from the link arm.
Fig. G10 Transport lock for gearbox.
Once link is free to move, the gearbox /
jockey wheel can be lowered by engaging the
hydraulically driven spinners from the cab of
the tractor.
To disengage the feed chain lift the
gearbox / jockey wheel by reversing the flow
at the tractor’s controls. This will stop oil flow
to the spinners and raise the gearbox in one
operation.
Use the transport lock if travelling
between paddocks or across roads.
