Today I learned that the Sears lawn tractors are useless in the snow without wheel weights and also chains. So.... we went to Sears to buy both, but, it turned out that the chains will not be available until Tuesday. Scot put the weights on and I found that the chains really are needed also. When I tried to go up a tiny hill, the wheels spun. So until the chains become available, it is no go.
I needed the little tractor to go feed the neighbors horses despite the snow that ordinarily stops my perambulation. Fortunately, after I became exhausted from the tractor no-go, Lona volunteered to go do the job of feeding the horses.
I bought a Sears model 4500 lawn tractor and snowblower attachment. It arrived too late for the attachment mounting process to be completed before the expected snowstorm. Later this week, Quick and I plan to take all parts to his garage where we hope to figure out the complexity and also to work in comfort. But it looks like we are going to be snowbound until then.
