Clutch Troubleshooting
Acremeter Inaccurate
Incorrect tire size or pressure.
Check against page 89. Meter is factory-pro-
grammed for the original tire size, pressure,
as well as sprockets to jackshaft.
Pass misalignment (overlaps or gaps) -
drill is actually covering more or less
acreage than is present.
Check/adjust markers.
Soil conditions
Loose soil or excess tire slippage causes
variations in registered acres (and variations
in seeding rates).
Acremeter revs/area incorrect
Check displayed revs/ac or revs/ha against
page 83.
Actual field size is different, and
acremeter is correct
Check field size.
Chain fouling
Clip reversed at link
