Check all your cables, make sure all connections are clean. Don't just look at them; unbolt/unscrew them. At the battery, at the starter, solenoid, and the frame/ground.
Check your cables closely, around the insulation.
I had a ground on my Kubota, that looked fine. But, when I removed the cable, found corrosion I was not able to originally see; it went up under the insulation. Turned out the battery was ok, but I needed a new negative/ground cable.
