The reason I say it was good is because its only about 2 yrs old and I know that doesn't man anything and I always 100% of time keep a battery tender on it when not in use. So even after I charged and jumped it with my jump box the solenoid clicked but no start. So do you still think it is battery or could it be solenoid? If battery was bad it should have started with the jump box or not? Appreciate all your reply's and suggestions.
Not necessarily.
I along with many others here have had batteries that were bad enough they would not take a jump or work off a jump box.
The first time it happened to me I was running the tractor just fine for an hour or so. Loaded it on the trailer - then travelled to the next job 5 minutes away. Jump on the tractor.....nothing.
Took it home - thankfully it was stuck on the trailer - tried jumping it, charger both fast and trickle - nothing. New battery the next day and it was fine.
What happens is one cell can get a short - then the battery won't work at all.
If you have a multi meter you can load test it yourself if you have another pair of hands or clips to attach the leads to the battery. With the meter connected read it
while the key is turned to the start position. If it drops to 10.5v or less the battery is bad.
Or you can take it to an auto parts store to have it load tested.
Or...if you have multiple equipment and vehicles, it's a good investment to get your self a cheap battery load tester. I use mine every fall to test the health of the batteries in everything.

With issues like you are having it is well worth the few minutes it takes to thoroughly check the battery before continuing on with any diagnosis. I've seen people throw hundreds of dollars of parts at a machine trying to guess what the problem is only to find in the end that the battery was bad to begin with.
