1. 

Lubricate pivot points on the blade and drive controls 

at least once a season with light oil. These controls must 

operate freely in both directions. See Fig. 6-1.

2. 

Lubricate the wheels at least once a season with light oil (or 

motor oil). If wheels are removed for any reason, lubricate 

surface of the pivot arm and inner surface of the wheel 

with light oil. See Fig. 6-1.

3. 

Lubricate the torsion spring and pivot point on the rear 

discharge door and side mulch plug periodically with light 

oil to prevent rust. See Fig. 6-1.

4. 

The transmission is pre-lubricated and sealed at the factory 

and does not require lubrication.

Follow the Maintenance section in the engine manual for 

lubrication schedule and instruction for engine lubrication.

Clean underside of the mower deck after each use to prevent 

build-up of grass clippings or other debris. Follow steps below 

for this job.
1. 

Disconnect spark plug wire. Drain gasoline from lawn 

mower or place a piece of plastic under the gas cap.

2. 

Tip mower so that it rests on the housing. Keep the side 

with the air cleaner facing up. Hold mower firmly.

Never tip the mower more than 90º in 

any direction and do not leave the mower tipped for 

any length of time. Oil can drain into the upper part 

of the engine causing a starting problem.

3. 

Scrape and clean the underside of the deck with a suitable 

tool. Do not spray with water.

4. 

Put the mower back on its wheels on the ground. If you 

had put plastic under the gas cap earlier, make sure to 

remove it now.

NOTE: Refer to the operation and maintenance sections in the 

accompanying engine manual for detailed instructions.
