Setting the Application Rate
The application rate of material is controlled by the back door settings and gear selection.
Refer to the rate charts in appendix 1 at the back of this manual for guideline settings of the
door opening in millimetres and which gear should be selected. Once you have selected your
rate from the charts, remove the retaining pins in the door handles and adjust the door so that
the top of the door indicator lines up with your selected figure on the chart. Replace the
retaining pins and check that both doors are level with each other. The rate is now set. With
the huge variation of prills and compounds it is impossible to be 100% accurate without
checking the batch of material you are spreading.
GEAR SETTINGS
Med..High..Low gear denoted on the table refers to the gear box selector on the inside of the
jockey wheel drive arm. Gear is selection is indicated on the decal on the gear box. Neutral is
between each gear. Always remember to replace the retaining pin after changing gear.
Use will dictate accurate settings.

gearbox to keep the engine from labouring. This will ensure the hydraulic flow will be
sufficient to maintain spinner speed.
