I've got a used John Deere LA145. After using it perfectly a few times, it started developing some issues that I am 99% sure has to do with the mower "thinking" the blades are engaged when they aren't.
Every time I try to start it after leaving it overnight, it gives one try, then sounds like it has a dead battery. Using a battery charger/jumper makes it start the first time.
Once it starts, you can flip the switch to start the blades fine, then it runs for 5-10 minutes, and eventually the blades cut out, but the mower keeps running. At this point, if I stop the engine, it will NOT start at all (even with the charger/jumper). It acts exactly like it does when it is in working condition and you try to start it with the blades on.
After I leave it out overnight, the next day this process repeats again.
I'm not a handy man, but I'd like to try to figure this out. Anyone have any advice?
