I got a new battery last year for the Tiger. Well today it was cranking slow, amp meter showing 0 or -5 with pto engaged, fuse blowed. Tested battery at Advance auto, checked bad, so I got another one. Seems like no one is having luck with mower battery's around here and I'm not sure if it's the batteries are defective or the charging system is not taking care of them. Do they make a good aftermarket ZTR Battery? The last one was a Interstate, and they are supposed to be good. Still have the original on the 05 Exmark.
