machine, stop engine and remove key from
the switch.
ENGINE CARE
The Engine Manual supplied with your Greens Aerator
provides the maintenance procedures for service of
the air cleaner, oil requirements, ignition components,
etc.
Note:
If Greens Aerator is to be operated at altitudes of
3000 feet or above sea level, it may require a high
altitude carburetor main jet. Order Part No. 8055537
from your Authorized Briggs & Stratton Service Dealer.

head; refer to Install Tines.
2.
Position a drain pan under chassis below pump
assembly (Fig. 28).
3.
Remove hose clamp securing return hose to

CHANGE TRANSAXLE OIL
Each year oil in transaxle must be changed. If possible
run machine just before changing oil. Warm oil flows
more freely and carries more contaminants than cold
oil.
