Operation
Adjust Tine Depth
To adjust the working depth of the tine, proceed as
follows:
1.
Remove the lynch pin from each depth adjust handle
(Fig. 19).

2.
Turn the depth adjuster handles to raise (deeper) or
lower (shallow) the roller.
Note:
Make sure that the roller is on the ground once the
depth is chosen.
3.
Depth guides (Fig. 20) are provided with numbers 1
through 27. Depth varies with the mounted angle of
aerator, tine type and amount of tine wear. Refer to
Depth Chart on page 16. Adjustment between two
numbers will give approximately 0.20 inches (5 mm)
change in depth. The higher the number, the deeper the
tine penetration. Always adjust each side to the same
number.

Important
If a large change in height is required,
adjust each leg by a small amount to ensure the roller legs
are adjusted as evenly as possible.
Note:
Remember when depth changes are made, you will
need to adjust the top link length to give the correct
machine angle. Refer to Connect Upper Link, page 8.
Important
Tine depth is affected by the mounted
angle of the aerator as well as the depth setting. If the
aerator is angled rearward, the tine heads may contact the
turf guards and damage may occur. Depths 26 & 27
cannot be used when the aerator is in the vertical position.
See Depth Chart.
4.
Install the depth adjust handle lynch pins before
running the machine, even if you are just testing for
correct depth.
Important
Tine depth is determined by the tine type,
depth adjustment, amount of tine wear and mounted angle
of the aerator. Refer to Depth Chart on page 18.
Important
Maximum depth is achieved when the
aerator is mounted vertically (Fig. 21) and the depth
adjustment set at 25. In this condition, do not operate at
greater depth settings, as there is minimal clearance
between the tine head and the turf guards. Never operate
with the aerator angled rearward or damage to the turf
guards may occur.
