Looking for some options. Went to start my tractor and it wouldn’t crank. Pulled the battery and cleaned all connections and checked voltage. It reads 6.35 which is full charge on a 6 volt battery. It’s only 6 months old. Put it back together and still nothing when I pushed the starter button down. I pulled another tractor in and jumped it from the the other tractor to the starter and it fired right up. Is there a chance my battery could be bad. I was wondering if maybe the push button is bad. Don’t want to start replacing stuff for no reason. I did try and jump it directly from the battery on the tractor to the starter and it barely cranked then stopped like it didn’t have enough juice. The other tractor was 12 volt so it turned it easily and started. What should I do Thanks
