6. Check that the tines line up with the center of the gaps
in the turf guards (Fig. 27). Adjust turf guards as
required and tighten the nuts.

7. Install remaining tines into #1, 3, 4 & 6 tine holder.
Torque all tine holder capscrews to 30 ft.–lbs.
When replacing all the tines, proceed as follows:
1. Raise the coring head and lock in position with the
service latch.
2. Loosen the tine holder retaining capscrews and remove
the old tines.
3. Insert the new tines into the tine holder.
4. Tighten the capscrews to recommended torque level.
5. Repeat procedure on remaining arms.
Setting the Coring Depth
To set the coring depth of the aerator, proceed as follows
1. Select the preferred tine for your application
2. Lay the tine on the tine depth decal (Fig. 28) with one
end lined up with the desired depth of aeration (see the
tine overlay on the decal).

3. Determine which letter setting the other end of the tine
lines up with and set the depth control lever to the
corresponding letter setting.
Note: As the tine wears, you may be able to reset the
depth setting to account for that wear. For instance, if your
new tine depth setting has you in the “G” setting, you can
reset to the “H” setting after 1/4 inch of tine wear.
Manual Ground Following
The only time the manual depth setting spacers are
required is if the TrueCoret ground following system is
not functioning due to damage to the feedback system
(turf guards, tie rod, and actuator assembly).
To use the manual depth setting, proceed as follows:
1. Remove the lynch pin retaining the spacers and depth
pins (Fig. 29).
2. Position the spacers above or below the bracket to
attain the desired coring depth.
• Thick spacers equate to 3/4 inch increments.
• Thin spacer equates to 3/8 inch depth increment.
• With all spacers on the top side, the depth setting is
4–1/4 inches.
