CONNECTING UP YOUR TRAILER
1. Connect the large diameter return hose to the return line breakaway coupling on your
tractor.
2. Connect the small diameter pressure hose to the pressure line breakaway coupling on
your tractor.
3. With the tractor at an idle, engage your hydraulic spinners. The right hand spinner
should rotate anticlockwise. The left hand spinner should rotate clockwise.
NOTE: If the spinners do not rotate or rotate the wrong direction then the delivery and
return hoses may have to be swapped over.
CAUTION !!
Spinners can be over speeded Check Your Tachometer !! Max. for 575 mm spinners 1300 rpm,
475 mm spinners 1600 rpm. On any new set-up always shut flow control before start up and
open up with tractor at Max. RPM until desired spinner speed, mark flow control setting to keep
Max. spinner speed within above parameters.
SETTING SPINNER SPEEDS
Spinner Speed is the most important factor in achieving an accurate spread pattern. The
spinner speed is adjusted by altering the control on the valve at the front of the machine.
Guideline speeds for various different materials are given in the table on page 16 . When
setting spinner speeds ensure the engine of the tractor is running at the same R.P.M. as it
will normally be operating in the field and make sure that the oil is warmed up to its
normal operating temperature. Always monitor the spinner speed by watching the
tachometer when operating the spreader as an error of 50 R.P.M. on spinner speed will
result in a deterioration of the spread pattern. If the spinner speed is to high there will be
to much material behind the spreader. If the spinner speed is to slow there will be to little
material behind the spreader.
SETTING THE APPLICATION RATE.
The application rate of material is controlled by the back door settings and gear setting.
Refer to the rate charts in appendix 1 at the back of this manual ( ensure you get the
correct density ) 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 pin in the door handle 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. 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.
