Knowing how to properly remove, install, and maintain the parts associated with your equipment will save you unnecessary damage and wear. For the Gravely ZT and many other mowers, being able to smoothly work with the deck will save you a lot of stress.

Before servicing your mower deck, set the parking brake and make sure that all parts of the equipment have stopped moving. Stop the ignition and take out the key. Disconnect the spark plug wire and place it away from the spark plug.

It is extremely important to wear proper protective clothing such as safety glasses/goggles and gloves while working around blades and power equipment in general.
