Acremeter inaccurate
Excess wheel slippage Check frame height. If correct, solution may
be to wait for drier conditions.
Passes misaligned Check that planting passes are not leaving
gaps (under-reporting area) or causing
overlap (over-reporting area).
Wheel slippage is varying from
nominal If variance is consistent, develop a correction
factor for your conditions.
Check that acremeter is for your drill. Activate display. Lower left corner must be:
3P606NT: 913.0 Revs/ac (2256.1 Revs/ha)
606NT: 995.0 Revs/ac (2458.7 Revs/ha)
Contact dealer if otherwise.
