Adjusting Tine Penetration

To adjust equally on both sides:

1. Loosen the capscrews securing both height adjusters

(Fig. 1). Raise the adjusters until the bolt bottoms out in

the slot.

2. Maximum penetration depth of 12.7 cm (5 in.) for 7/8

in. (2 tine) and 7.6 cm (3 in.) for 3/4 in. (6 tine) config-

uration. To adjust for less penetration, lower the height

adjusters.

3. After adjusting to the desired depth setting, tighten the

mounting capscrews to secure the adjustment. Adjust

the height adjuster on the opposite side to the same set-

ting.

Check the Reservoir & Gear Case

Oil Levels

1. With machine on level surface, remove the oil fill/dip-

stick plug from the right-angle gear case (Fig. 2).

2. The oil level should reach the mark on the dipstick. If

oil is needed, add SAE EP 90W gear oil. Install the fill

plug.

3. At the rear of the machine, remove the dipstick assem-

bly from the reservoir. The oil level should be between

the marks on the dipstick (Fig. 3). If oil is needed, add

SAE EP 90W gear oil. Replace the gear case cover.

Timing The Aerator To The Tractor

To operate the aerator correctly, set the tractor as follows:

1. There must be 540 PTO rpm at normal engine operating

speed.

2. With the PTO operating at 540 rpm, select a transmis-

sion gear that allows the tractor to operate 30.5 m (100

ft) within 30–38 seconds; i.e., 2.9–3.5 km/hr (1.8–2.2

mph).
