John Deere S120 -30 second oil change - 1st time! #johndeere #oilchange #s120 #diy #lawncare

This is a quick, first-time DIY oil change on a John Deere S120 lawn tractor, done at the 8-hour mark using the tool-free filter system. It covers warming up the engine, removing the zip tie, twisting off the old cartridge filter, and locking in the new one, plus the 50-hour/annual reminder. It's a short, narrow how-to for S120 owners doing their very first service, not a broader review or performance overview.
