So, for a while now, the GT battery has been having trouble holding a charge and I now can't get the tractor to start even when doing a 60 amp jump from the charger. Charger tells me the battery is full, but it barely has enough oomph to turn the motor even once. Original is only 235 CCA, and I'd like to get something better.The original has been marginal from the git go. I can maybe get one at the local Auto Value (I'll need to check), or Wally's house, but I'd like some opinions first. I need the tractor back. I use the darn thing year round, and I'm getting behinder on some stuff w/o it. Wood hauling comes to mind. Any ideas?
