4 meter vicon air drill

[Billy h]

I bought a vicon 4m air drill for sowing grass seed can anyone tell me if it should be on the fine seed setting or normal setting
Thanks

I use normal on a 3m LZ304. Just remove the springs and let the coulters drag.

Ok thanks, what number setting do you have your machine set at for grass ?

So many variables, size of the seed etc, you really should do the calibration by taking off the 90 degree air pipe bend under the metering unit, put a container underneath, reset the area meter to zero, rotate the metering unit with the hand lever, or spin the wheel untill you get an area of 0.04 hectares, equal to one tenth of an acre. So if your seed rate is say 14 kg an acre ,you should weigh 1.4 kg in the container.

I normally drill twice at half rate, and use the fine roller setting but not the slow speed gearing.
As above, calibration is very quick and easy.

Seed rate work out spot on
