My craftsman riding lawnmower came with the house I bought. I've found blades at Lowe's that fit. I pulled a boner and measured the blade belt thinking I could just buy one of the same size and it would fit, but that was a wrong move. My strategy to buy some other brand backfired, especially when I learned I could have bought the craftsman for only a couple bucks more.

My problem is with the Kohler engine. If I buy an oil filter from a Kohler distributor, it is $15. I can get a Napa replacement for only $4.

Good thing: parts availability.
