John Deere Z335M riding mower oil change

Sorry for the plumbers crack in the sped up parts (not really but my coat kept pulling my shirt up and I'm 6'4" so I needed a long shirt). Doing an oil change on my John Deere Z335M 42" zero turn riding lawn mower. The whole process involved cleaning it, changing the oil filter, fuel filter, air filter, and spark plugs. I also slow charged the battery and siphoned old gas out of the mower since it sat all winter. Aired up the tires and determined the blades were fine. If you're doing this, do it in fall, run the mower (use it) to warm the oil up, drain the oil and change the filter, put in 2 new quarts, change the air filter and spark plugs, and run it again until the gas is out. That way in the spring when you put gas in it will be fresh. Should take you about 30 minutes tops if you don't clean it like I did, lol.
