Acremeter inaccurate
Excess wheel slippage Check frame height, wheel axle position, tire
size and pressure. 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
“656.2 revs/ac” or “1621.5 revs/ha”. Contact
dealer if otherwise.
Acremeter battery exhausted Replace acremeter (unit is sealed and
battery is not replaceable). See page 59.
