So I scored a free round of mulch-quality hay Jim Hunter was giving away...
And when I got home I went to unload it and the tractor wouldn't start :/
I was able to engineer a temporary repair, but since she is under warranty I sent the tractor to the dealer to have the cable properly replaced. There was a bad batch of batteries, so I'll use some sealant on the terminal (and dielectric grease) to keep this from re-occuring.
I also splurged on a walk-behind string trimmer which is a lot faster than the one I carry. Still haven't caught up because with my sprained foot I still need to get back up to speed & stamina.
