Knock Down Operation
Knock downs require no specific procedures during field
operations, other than to periodically check that
clearances and gaps remain correct.
Accelerated Wear Risk:
Under no circumstances allow the polymer bar or tine to
contact the ground during operation. The knock down kit is not
designed for use as a row cleaner, and will wear rapidly if so
used.
Knock Down Maintenance
Knock Downs
2 tines per row
Clean away any debris that has collected ahead of the
opener disc or between the polymer knock down bar and
the disc.
Inspect the adjustment bolt/nut settings to ensure
desired polymer bar-to-disc gap is being held. Inspect
the tine and replace if not flat along the polymer bar.
Inspect polymer bar for wear, chipping and cracks, and
replace as necessary.
Check Grade 2 torque on the bolts holding the bar to the
tine.
