Checking the Springs

Service Interval: Before each use or daily
Check the springs for crossed or broken wires
51). Crossed or broken spring wires will cause an
erratic hole pattern in the turf.

1. Correct spring wires
Note:
The aerator includes replacement wires. The
wires are a consumable item.

Adjusting the Hole Spacing

The forward hole spacing is determined by the traction
unit gear ratio (or the hydrostatic traction pedal)
Note:
Changing the engine speed does not affect
the forward spacing.
The lateral hole spacing is determined by the number
of tines in the tine heads.

Removing the Aerator from

1. Stop the aerator on a level surface, not on a
slope.
2. Disengage the PTO and engage the parking
brake.
3. Raise the aerator roller(s) 7.5 to 15 cm (3 to 6
inches) off the ground. Place support blocks
under the roller(s).
4. Shut off the engine and remove the key.
5. Before leaving the operator's seat, shut off the
engine, remove the key, and wait for all moving
parts to stop.

aerator bracket. Retain the pin with the aerator.
Also, on models with a hydraulic top link,
disconnect the hydraulic hoses and the
connecting link from the traction unit. Cap the
hydraulic hoses. Store these components with
the aerator.

shaft.
11. Pull back on the lock collar to disconnect the
power shaft from the traction unit PTO shaft.
12. Slide the PTO shaft back and remove it from the
traction unit.
13. Connect the PTO safety chain to the aerator
to prevent the PTO shaft from contacting the

the aerator brackets. Retain the pins with the
aerator.
