Replacing the Mow-Ball ® or Cord Head
Tools and Supplies Needed:
 Phillips head Screwdriver with at least a 6" shank

Gloves
1. Align the hole in the Anti Wrap Canister with the hole in the internal housing
at the location shown (Figure 23).
2. Insert a Philips Head Screwdriver into the hole in the Anti Wrap Canister
and the hole in the internal Housing.
3. Rotate the Mow-Ball ® Assembly until the Screw Driver slides into a hole in
the shaft, locking it into place.
4. Looking down at the top of the Frame, turn the Mow-Ball ® clockwise until it
unscrews completely from the Bearing Housing.
Note: If the Mow-Ball ® continues to turn, but does not come off, check to be sure
that you locked the Screwdriver into the shaft.
If the Mow-Ball will not turn by hand a 9/16" Socket can be used on the Bolt (inside
the bottom of the Mow-Ball) to loosen it. You may need to clean grass or debris out
of the recess first.
5. Slide the Cord Head, Adapter and Molded Spacer off the Shaft (Figure 24).
6. The Anti-Wrap Can and Spacer should remain on the Shaft with the
Screwdriver.
7. Replace parts as needed and install them onto the shaft in the order shown.
8. Place the head of the Mow-Ball ® Bolt so it is sitting in the hex cavity at the
bottom of the Mow-Ball ® .
9. Looking down at the top of the Frame, hold the Bolt Head in place with your
finger and turn the Mow-Ball ® counterclockwise to start the Bolt into the
Shaft.
10. Tighten the assembly securely by turning the Mow-Ball ® counterclockwise
when looking down on the top of the Frame.
