In my humble opinion, me-thinks the single-stage snowblowers should come already with the holes drilled into the side housing, ready to support an optional two front wheels as an option. Having the holes present, designed by the single-stage manufactorer with knock-outs so the user would not need to drill the two holes, himself, would be an innovative design improvement. This way the two front wheels could be sold as an option and much easier to do than drilling two new holes and possibly making a major boo-boo with the drilling.

You know that lawn mowers all have four wheels, so why not single-stage snowblowers, as well? installing front wheels on a single-stage snowblower seems like a good design improvement.
