1. Battery goes dead when using headlight's (yes the engine Is running, but light's get dim and wont restart when u shut It off, needs jump).
2. Battery goes dead If cranking more than 10 seconds.
If I take the spark plug boot off and engage the starter, It spins fast then starts to slow down and eventually stops spinning, then I need to jump It.
Yesterday I was mowing my neighbors yard front and back and got Into some deep heavy grass and stalled before I could disengage the blades. Started right back up but hesitated, while Im holding the key In start It cranks over stops then continues cranking and finally starts. So I hooked my jumpers from my Jeep to the mowers battery and cranked It up over 10 times and It started instantly each time. Also I had the battery on the charger for over 12 hours and It couldn't even crank the engine for 10 seconds, but when I hooked up the jumpers It cranked for as long as I had the key turned. So Is this just a simple battery replacement? I also took It up to AutoZone and had It tested/charged 2 times and they said It passed both times. But when I put It back on the mower It still couldn't crank It for more than 10 seconds. But again when I hooked the jumpers up It cranked as long as I held the key. It's a DEKA battery. Battery Is only 2 years old but was dead all winter and a few months before that.

You've got one indication of a good battery (Autozone test) but everything else indicates a bad battery.
Have another place test it.
Also, it sounds like your charging system is not working if the battery goes dead with the headlights on. It would go dead eventually, even with the lights off--it would just take longer.
