Preparing the Machine
1. Park the machine on a level surface, fully raise
and latch the handlebar to engage the parking
brake, shut off the engine, remove the key, and
wait for all moving parts to stop.
2. Remove the coring-head cover; refer to
Removing the Coring-Head Cover (page 68) .
3. Secure the coring head with the service latch;
refer to
Supporting the Coring Head with the
Service Latch (page 50) .
Adjusting the Roto-Link
Dampeners
Note:
The factory positions 1 roto-link spacer at the
roto-link dampener shaft and 1 spacer is in the stowed
position for each stomper arm.
Note:
Adjusting the roto-link dampers allows you to
operate the machine at full engine speed (3400 rpm),
however you may need to aerate at slower engine
speeds to improve the hole quality.
1. Remove the 2 flange locknuts that secure the
roto-link dampener shaft to the rear frame of the
machine (
Figure 131 ).

4. Position the roto-link spacer to correct the
following hole-mounding conditions:
Note:
Each spacer is equivalent to 12.7 mm
(1/2 inch). The lower bumper-spacer must
remain assembled to the damper shaft.
•
If the front of the holes is slotted or
tufted—position the spacers above the rear
frame, in the stowed position.
•
If the back of the holes is slotted or
tufted—position both spacers above the rear
frame, at each side of the roto-link dampener
shaft.
5. Rotate the dampener link and dampener shaft
up, and insert the studs through the holes in the
rear frame of the machine.
6. Secure the dampener shaft and spacers to the
rear frame with the hardened oval washers and
locknuts (
Figure 133 ).
