GENERAL ________________________________________________________________

!
WARNING
To prevent injury, disengage master clutch, lower
aerator head to the ground, stop engine and
disconnect spark plug wire before making any
adjustments or performing maintenance.
Make sure the aerator is parked on a solid and level
surface. Never work on a tractor that is supported
only by the jack. Always use jack stands.
If only the front or rear of the unit is raised, place
chocks in front of and behind the wheels that are not
raised.
1. Adjustments and maintenance should always be
performed by a qualified technician. If proper
adjustment cannot be made, contact an authorized
Jacobsen Dealer.
2. Replace, do not
components.
6.2

TURF GUARD _____________________________________________________________

The turf guard (C) is used to prevent the turf from lifting
up as cores are pulled out. The pressure on the turf
guard can be adjusted by increasing or decreasing
tension on the springs (A).
Add or remove spacers (B) above spring as required so
the turf guard provides enough presure to prevent turf
from lifting up, but not so much that they mark or cut the
turf.
