I've got an old 72" scag walk behind. It's a great mower but on rough ground the corners of this wide deck sometimes dig in. I'm thinking about adding a set of 8" push mower wheels to each side of the mower deck. Just bolt them onto the deck edge near the front of the deck. Most of the time these extra wheels would just hang in the air. But if the deck edge was going to dig in, it would roll on these wheels instead. Just wondering if anybody's done this or if anybody's got a smarter solution. Thanks.
