Deere 35D trouble starting

Checking in to see if anyone has some advice. I have a 2014 Deere 35D with around 900 hours on it. Over the last month or so it has slowly taken longer and longer to start in the mornings. Then once it's started it usually starts immediately after turning the key the rest of the day. Yesterday it did the same thing, but after it sat for a few hours it took about 10 seconds of cranking to get it to start again to move it at the end of the day.

This morning it wouldn't start. Tried cranking...
