Well shucky darn. That didn't go well either. Got the battery back to the mower and then found I was missing one of the battery bolts. I had dug the car keys out of the pocket to get in the trunk where the chainsaw gas oil was. Bolt must have come out with the keys. Add 'get bolt' to the to-do list for tomorrow.
Fixed....I hope. No go on the recharged battery, still dead after a couple hours on charger. Took it to the dealer down the road 1/2 mile and test showed it was bad. IIRC it has been on the mowere many years. Ran to town for a new battery. They were out but promised a new one would be there at about 7am tomorrow.
I didn't buy one from the dealer because of the raping they gave me last yiear for annual service. Lube, oil, clean deck, etc. plus 1 new belt and a gasket. $454 Pape Machinery.
