Adjust Tine Depth

To adjust the working depth of the tine, proceed as

follows:

1. Remove the lynch pin from each depth

adjustment handle (Fig. 18).

2. Turn the depth adjuster handles to raise (deeper)

or lower (shallow) the roller.

3. Depth guides (Fig. 19) are provided with

numbers 1 through 27. Depth varies with the

mounted angle of aerator, tine type and amount

of tine wear. Refer to the Depth Chart. Tine

depth between two numbers is approximately

0.20 inches (5 mm). 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 the Upper Link.

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 the Depth Chart.

4. Install the depth adjustment handles’ 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 and mounted angle of

the aerator. Refer to the Depth Chart.

Maximum depth is achieved when the aerator is

mounted vertically (Fig. 20) 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
