I purchased a Troy Built Super Bronco 42inch deck last summer and want to get more yards this summer. I have 1 yard that is constant right now, but want to get at least 5-7 part time. I use a bolens 20 inch or so push mower to get close and a sthill residental trimmer. How much faster could I mow with a walk-behind with skids to stand on? I was looking at a few eXmarks at a dealer this week. Or would I be better to keep the 42inch rider? It is lightly used and could probably sell it for a decent amount.
