I have a new to me amazone adp 402 profi air drill, am trying to calibrate to get barley drilled at 300kg/ha
This is an old drill so hopefully someone on here maybe able to help, it has the old style green gearbox on so you remove the plate and turn the bottom cog around to switch between fast and slow. The most I can get out of a calibration test is 6.3kg at 17 turns that equals 1/40 of a ha so times my 6.3 gives me 252kg/ha, I have checked that the gear box is on the fast cog and the above rate is with the slide as far as it can go even past the 100 setting.
many ideas?
Thanks
