8.7.1 SICKLE SECTIONS
Check daily that sections are firmly bolted to the
sickle back, and are not worn or broken.
Damaged or worn sections leave behind uncut
plants.
Coarse serrated sections last longer than fine
serrated sections in dirty or sandy conditions.
Fine serrated sections perform better in fine
stemmed grasses and plants that contain more
fibrous stems.
A worn or broken sickle section can be replaced
without removing sickle from cutterbar.
