Section 2: Assembly

Disconnect the spark plug wire from the
spark plug before attempting to install
the cutter bar. Move the spark plug wire
away from the spark plug and prevent the
wire from contacting the plug.
5. Center eccentric arm (A, Fig. 2-14), if
necessary, by moving cutter bar lever to
ON (Fig. 2-15) and pulling starter rope.
6. Position the cutter bar (B, Fig. 2-9) at
the front of the cutter bar mounting
bracket (C) as shown. Place the doubler
bracket (D) on the cutter bar and align the
three mounting holes as shown.
7. Apply a small amount of Loctite®
Thread Fastener (use only a small amount,
as a total of five screws need to be coated
during the assembly procedure) to the
threads of the three 3/8-16 x 1-1/4 hex
cap screws (E, Fig. 2-9). Have an assistant
hold the unit firmly by the handlebars and
raise the front of the unit a few inches off
the ground. Securely attach the cutter bar
and doubler bracket to the cutter bar
mounting bracket with the three hex cap
screws (E), 3/8 flat washers (F) and 3/8-
16 center locknuts (G). Torque to 35 ft-
lbs. if you have a torque wrench. Lower
the unit to the ground.
IMPORTANT: Allow the Loctite® to cure
for at least one hour (preferably 24 hours
at 72oF.) before operating unit.
8. Align the middle hole (B, Fig. 2-10) in
the cutter bar with the middle locknut (CC,
Fig. 2-10) on the cutter mounting bracket.
If needed, tap the ends of the cutting blade
back and forth (see inset, Fig. 2-10) to
align the middle hole (use a wood block to
avoid damaging the blade).
9. Slide the pitman assembly (H, Fig. 2-
10A-1) onto the post of the knife head (I).
The “Top” decal on the pitman assembly
must be facing up. Remove the two 5/16
hardened flat washers that are wire-tied to
the knife head for shipping purposes.
