Support until the

screwdriver fits in the second hole in the inner shaft, locking it in place.

3. With your hands, turn the Mow-Ball

™

Support

assembly with your hands until it completely
unscrews from the bearing housing (Figure 27).

4. Reassemble the components in the order shown

in Figure 28, adding the additional cutting
height disk above or below the one already
installed.
• Be sure to align the notches in the cutting
height disks and the Mow-Ball

™

Support

before completing assembly.
• Check the head of the Mow-Ball

™

should sit in the groove (square washer) at the
bottom of the Mow-Ball

™

Support.

5. Keeping the bearing housing locked with the

finger and turn the assembly onto the bearing
housing until it's finger tight.

6. Spin the Mow-Ball

anti-wrap device does not hit the trimmer head

clearance between the top of the flat plate and
the end of the anti-wrap bracket. There will be
some resistance as you turn the trimmer head
because of the belt and pulley.
