MAINTENANCE/SERVICE
SICKLE AND SICKLE DRIVE
WARNING: Keep hands clear of the
area between guards and sickle at all
times.
CAUTION: Wear heavy gloves when
working around or handling sickles.
Sickle Lubrication
Apply SAE 10 or equivalent light weight oil daily
(one or two drops per section) along entire length
of sickle.
NOTE: Do not oil sickle if operating in sandy
conditions. Oil will cause sand to adhere to sickle
components, resulting in excessive wear.
Sickle Sections
Check daily that sections are firmly bolted to the
sickle back and are not worn or broken. Replace
as required.
To replace sickle section:
1. A worn or broken sickle section can be
replaced without removing sickle from
cutterbar.
2. Remove lock nuts (A) and lift section off of
bolts.
IMPORTANT: Do not mix heavy and light
sickle sections on same sickle.
3. Clean any dirt off of sickle back and position
new sickle section on bolts. Secure with lock-
nuts.
