I am new to winter tractor use also. From talking to friends and surfing the tractor forums weight is important when pushing snow, chains are needed when doing anything on ice or grades. I went with both by ordering some v-bar chains and getting my rear tires filled. I am using a TYM t353 with a Meteor 68' snow blower for maintaining my long drive and a portion of our private road. Both have steep areas and ice is a common occurance on the road.
