BLADE ASSEMBLY FOR ALL TRACTORS
STEP 1: (SEE FIGURE 15)
• Assemble the two angle lock bars together as shown
in figure 6, so that all holes are aligned. Use one 3/8"
x 1-1/4" carriage bolt (E) and one 3/8" nylock nut (L).
Be sure to insert bolt from side indicated. Do not
tighten at this time.
• Hold the angle lock bars so that the square holes are
at the top. Insert the straight hook end of the angle
lock spring through the small middle hole in both
angle lock bars.

STEP 2: (SEE FIGURE 16)
• Insert the round hook end of the angle lock spring up
through the hole in the spring mount bracket.
• Insert the angle lock bars down through the slot in the
channel. Underneath the channel, place a 1" long spacer
(U) on each side of the angle lock bars and insert a 1/4"
x 3-1/4" bolt (A) through the channel, angle lock bars
and the spacers. Secure the bolt with a 1/4" nylock nut
(J). Tighten so that lock bars can pivot freely.
• At this time tighten the 3/8" carriage bolt and hex nut
previously assembled to angle lock bars.
NOTE: When the angle lock bars are pulled back in slot,
the pivot plate should unlock and be free to pivot to the
right or left position.

• Using a hammer, assemble a 3/8" palnut (S) onto one
end of the spring mount rod. Insert the other end of
the spring mount rod through the pivot plate using the
rear set of holes. Support the assembled end of the
spring mount rod on a block of wood, and assemble
the remaining palnut onto the other end of the rod.

STEP 4: (SEE FIGURE 18)
• Assemble a 3/8" x 1-1/4" carriage bolt (E) through
the square hole in the cable mount bracket and
through the square hole in the angle lock bars. (The
carriage bolts should face in opposite directions.)
Using pliers hold the cable mount bracket in position,
angling down towards the L.H. hole in the channel as
shown in figure 15. Secure with a 3/8" nylock nut (L).
Tighten. Refer to the figure for the correct angle for
the cable mount bracket.
