ADJUST THE CORING DEPTH
1. Raise the coring head and engage the lock-up brack-
ets.
2. Loosen the jam nut on top of the adjusting bracket
(Fig. 11).
3. Thread the adjusting screw into the bracket to
increase coring depth. Thread it out to decrease
depth (Fig.11).
4. Repeat this procedure using the long end of the
height gauge on each rear wheel spindle (Fig. 13).

5. Best recommended coring depth is achieved when the
distance from the end of the screw head to the brack-
et is
11
⁄16” (Fig. 11).
IMPORTANT: Do not adjust the screw to a setting
less than
11
⁄16” or damage to turf guards may
occur.
6. Make sure adjustments are the same on both sides of
the coring head and tighten the jam nuts.
CHECK FRAME HEIGHT
1. Position the machine on a level surface.
2. Slide the short end of the frame height gauge under
the front axle to verify height. The gauge should
contact the axle when on the floor. Check both sides
(Fig. 12).
