cutter bar will break away more easily, turn nut (E) counter¬
clockwise to increase the length of spring (D). If it is desir¬
able to adjust the break away mechanism so more force is
required before it will swing back, turn nut (E) clockwise to
decrease the length of spring (D).
CAUTION: DO NOT
OVER TIGHTEN THE BREAK AWAY MECHANISM.
NEVER TURN NUT (E) MORE THAN 2 COMPLETE
TURNS CLOCKWISE WITHOUT TESTING THE CUTTER
BAR TO SEE IF IT WILL STILL BREAK AWAY. THE
BREAK AWAY MECHANISM MUST OPERATE TO PRO¬
VIDE OPERATOR SAFETY AS WELL AS PREVENT
DAMAGE TO THE MOWER.
SICKLE BAR REGISTER ADJUSTMENT
See figure 17. To operate most efficiently, the sickle knives
(B) must center in the guard (C) as shown, when the sickle
drive mechanism is turned so that the sickle knife is as far to
the right as it will go. If adjustment is required, proceed as
follows:
1. See figure 17. Rotate the mower drive mechanism by
hand turning the drive pulley until the sickle knife is as far
to the right as it will go.
CAUTION: USE CARE WHEN
WORKING AROUND THE CUTTER BAR ASSEMBLY,
THE KNIVES AND GUARDS ARE VERY SHARP.
2. Remove capscrew (D) and raise bearing housing (E) out
of the sickle head assembly (F). Be careful not to allow the
washers on either side of the bearing housing (E) to fall out
of place.
3. Move the sickle knife (B) until it is lined up as shown with
the nearest guard (C).
4. Turn bearing housing (E) clockwise, or counterclockwise
as required to line it up with the sickle knife head (F) so cap¬
screw (D) can be inserted without moving either the mower
drive mechanism or the sickle knife (B).
NOTE: BUSHING
ASSEMBLY {E) WILL HAVE TO BE TURNED FULL
REVOLUTIONS SO THAT GREASE FITTING (H) ISON
TOP WHEN IT IS REASSEMBLED.
5. Install capscrew (D) and tighten the nut securely.

MAINTENANCE
ORDERING REPLACEMENT PARTS
Replacement parts required for performing maintenance
services or repair work should be purchased from your
Simplicity dealer. When ordering parts be prepared to give
him the identification number of your sickle bar mower
If you have not already recorded this number on the inside
front cover of this manual, we suggest that you do so now,
for convenient future reference.
AFTER EACH USE
Inspect the sickle bar mower thoroughly, looking for any
loose or missing bolts, pins, or spring clips; or worn, or
damaged parts. Clean or repair the sickle bar mower as needed
to insure that it is ready to use the next time you need it.
