4. Knive sharpening
Field test results indicate the knives
can best be
resharpened
after approximately 500 bales in clean
crop conditions. In contaminated crop
conditions
resharpening may be necessary after 200 bales.
Grind on the smooth side of the knife

on the notched side.

ones on the outside and vice versa, to
equal out their
wear pattern
