I confess that I loved my riding mower. It took a lot of rational thinking and logical arguing with myself to finally let it go. It was my first major purchase ofter DH's passing and I maintained the farm property with that tractor so well.
My little lot in town does not need a tractor. But the yard was mostly a gravel pit when I moved in to my new house so I hauled needed topsoil, multi-year layers of mulch and planted trees and shrubs which were easily moved with the tractor and its little cart so I was pleased to have it. The property is lovely now and thriving.
Last year I realized that the annual maintenance costs exceeded the benefits in mowing so have spent about a year arguing with myself. But I am now at peace with the decision.
The deciding factor in so many situations is getting the emotion out of the equation which is sometimes really hard
