How to Lubricate Mower Decks


Riding lawn mowers are certainly the most effective of lawn care equipment. High precision machines require a high level of maintenance, and a riding mower is no exception. Oil changes, air filter cleaning and engine care only scratch the service. An often neglected part of riding mower maintenance is the cleaning and lubrication of the lawn mower deck. Failure to lubricate the deck can cause jamming, premature wear and eventual failure of the mower's deck components.

Step 1

Engage the mower parking brake, and remove the key from the ignition switch. Remove the cable from the spark plug to prevent the mower from turning on during maintenance.

Step 2

Remove the mower deck according to the instruction in your mower manual. Each mower is different, having a separate removal procedure, but many come with a safety catch that you can disengaged. If a mower manual is not available, contact your local mower dealer.

Step 3

Spray excess grass from the mower using a garden hose, and wipe down with an old rag.

Step 4

Inspect the mower deck for lubrication linkages that require greasing, or check your owner's manual for the points.

Step 5

Clean excess grease from the deck bearing using an old rag to prevent old, dirty grease from getting packed into the deck mechanism.

Step 6

Attach the grease gun tip to the lubrication points, and give two pumps from the gun. Do not over grease the point. Clean the lubrication linkage to clear away excess grease. Attach the mower deck to the mower.
