I am not at my farm and my tractor will not start. I had a walmart n1 battery in it but they no longer make it. So what size battery do i need. Such as cold cranking amps
The M4900 battery tray is huge so pick out Walmart's biggest best battery with the right terminal orientation. Their CCA is 800+. The M4900 doesn't need a large CCA - it will start fine with less but the bigger batts seem to last longer if they sit a long time between uses.
