Problem
Possible Solution
4.
Difficulty obtaining High Rates
Check the variator setting guide (pages
41 to 55) to obtain more information on
what can be expected from the metering
system.
Check the meterwheels are not damaged
in some way and have been fitted to the
metershaft in the correct orientation.
Check that the meterwheel cover plates
have been removed (refer page 110).
Check that the main drive sprocket ratios
have not been altered (refer ‘Parts
Section’).
Material bridging may be occurring if
sowing difficult product. Refer to page
112 for oats. If product is fertilizer, check
that it is not wet.
Check that there is no blockage inside the
bin at the meterbox.
Check that the variator is being adjusted
correctly when operated through the
cable. The variator should not turn when
adjustment is set at zero. Check grub
screws that retain the arm onto the
variator are tight.
Check the variator for damage (refer
page 62).
Change the sprocket ratio over to the
high ratio setting on the particular
meterbox if required (refer page 63).
Increase ratio only if recommended.
5.
Seed Dribble occurring
Block off unused primary tubes at the
meterboxes. (Refer page 11
1, ‘Blocking
Air Flow’ for further information).
Check that the meterwheel cover plate is
fitted. Refer page 112 in the metering
oats section.
Check for air leaks on the meterbox
hatches and bin lids.
Check for even airflow coming from the
plenum chamber attached to the seeders
blower.
Check all primary hoses for a severe
blockage that would cause an uneven
pressure or airflow in the system.
6.
Metershaft not Turning when Drive
System is engaged.
Check drive pin and drive shaft on the drive
end of the SR metershaft assembly.
Check metershaft is fully engaged.
