4.6 Metering motor – manual override/Half-Width Shut off (HWSO) drilling
As fitted to 6m and above drills. When wanting to only drill with one half of the machine, it is achievable
by switching either the right or the left hand side motor. Seed is then delivered to just one of the
distribution heads and subsequently just one half of the machine.
Simply press the desired key(s) to switch off either the left half or the right half of the machine.
The metering motor(s) can be stopped using this system manually as desired, if for example:
(a)
An area of field needs further cultivation before seeding.
(b)
In the case of a front-mounted hopper, the metering motor is switched off just before the
end of the bout to clear the seed through (the opposite of the ‘pre-start function).
(c)
You want to drill at half-width in order to correctly align tramlines
When half width is enabled the main screen displays as follows:
Figure 12. Usual operating screen for single product, dual metering.
With one half shut down (the right in this case) the screen displays as follows:

If left or right is switched off and a product calibration is initiated the following screen is shown:
