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.
