I got a bigger 350 CCA U1 SLA battery. But the battery is not really the problem as the frequent starting regime when hauling, the time the engine is running doesn't get the battery topped off. The battery in it now is 4 years old and as long as it was start and mow things worked OK. Plus it was seldom used when cold. 6 years ago or so I started using it to haul wood mulch. That killed that battery. So I guess using a charger to keep it topped off at the end of the day will be in order.
