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 the Greens Aerator is to be operated at altitudes
of 3000 feet or above sea level, it may require a high alti-
tude carburetor main jet. Order Part No. 8055537 from
your Authorized Briggs & Stratton Service Dealer.
CHANGING HYDRAULIC SYSTEM
OIL
The hydraulic system oil must be changed immediately
when any contamination, sludge, water or condensation
appears.
1. Remove the tines from the tine blocks and lower the
coring head; refer to Install Tines.
2. Position a drain pan under the chassis below the
pump assembly (Fig. 25).
3. Remove the hose clamp securing the return hose to
the pump. Disconnect the hose from the pump, allow-
ing oil to flow into the drain pan.
4. Connect the return hose to the pump and secure it
with the hose clamp.

5. Fill pump reservoir; refer to Checking Hydraulic
System Fluid.
6. Check all connections for possible leaks.
CHANGING TRANSAXLE OIL
Each year oil in transaxle must be changed. If possible,
run the machine just before changing oil. Warm oil flows
more freely and carries more contaminants than cold oil.
1. Place a drain pan below the drain plug on the axle.
Clean the area around the drain plug (Fig. 26).
1. Drain plug
2. Fill plug
2. Remove the drain plug and allow oil to flow into the
drain pan. After oil is drained, install the drain plug.
3. Remove the fill plug (Fig. 26) and pour approx. 1.89 l
(64 oz.) of SAE E.P. 90 wt. oil into the extension
tube. Stop when the oil level reaches the top of the
tube.
4. To check the oil level in the future: remove the plug
and add oil as required to bring the level to the top of
the tube.
