16 DR ® LAWN AERATOR
Adjusting the Drive Cable
For proper Belt tension the Drive Cable Spring should have gaps of 1/16"
between the coils when the Tine Engagement Bail Bar is pulled all the way to the
Handlebar. If there is less or much more than 1/16" then the Drive Cable
should be adjusted.
Tools and Supplies needed:

6mm Wrench

10mm Wrench
1. Hold the hex of the Cable adjuster with a 6mm Wrench and loosen the Jam
Nut with a 10mm Wrench (Figure 24).
2. Screw the Cable Adjuster in a few turns towards the Spring to tighten the
Spring tension. Turn it a few turns away to loosen the Spring tension.
3. Pull the Bail Bar to check Spring tension and continue adjustment as
needed.
4. Tighten the Jam Nut against the Cable Adjuster when adjustment is finished.
Replacing the Wheels
Tools and Supplies needed:
 Two 15/16" Wrenches
1. Lift the DR LAWN AERATOR Wheel off the ground with Blocks or Jack
Stands and remove the Locknut from the Wheel Bolt with two 15/16" Wrenches
(Figure 25).
NOTE: The front Wheel Locknuts can be accessed from the top of the Frame so
lifting the Wheel just off the ground is enough. The rear Wheels however will need to
be lifted enough to access the Locknuts from underneath.
2. The Frame is threaded for the Wheel Bolt. Remove the Bolt from the Frame
with a 15/16" Wrench.
3. Position the new Wheel and reinstall the Wheel Bolt until it is snug with the
Wheel but not tight so the Wheel still turns freely.
4. Reinstall the Locknut onto the Wheel Bolt.
5. Lower the machine to the ground.
Replacing the Tines
Tools and Supplies needed:

15/16" Wrench

7/8" Wrench
 7/16" Wrench

Jack Stands

Wheel Chocks
1. Remove the four Bolts and Flat Washers that secure the Cover using a 7/16"
Wrench (Figure 26) and remove the Cover.
