just remeber that sears is only a house brand,could have been built by any outfit,but to standards that allow sears to stand behind it.
now for the important question,do you want the mower only for cutting grass[if so buy sheep]or do you maybe want to get into racing,if so a whole lot of factors will have to be considered.
many more than if you want the mower for doing something as mundane as "mowing" the grass
when every one starts to buy mower's for actually mowing,you know were in for trouble. have a great day
