Anybody using them? When I first started mowing everyone told me stay away from non-commercial stuff, the Home Cheepo machines are junk, specifically the blade speed has to be lower to comply with the Consumer Protection Act. So I bought a used commercial WB and it's great but getting old and I'd like something to sit on for bigger jobs. So my question is, I've looked at the Cheepo and Lowes stuff, and it's not anything I would consider buying. But I keep finding deals on residential type ztrs that are sold by the dealer and not big box stores. I'm told the dealer models are much better than the ones sold through the box stores. Having trouble finding the info relating to blade speed specs. Does anybody use quasi-residential machines? I know commercial is better by far, but I don't have $10,000 to spend, and I only mow part-time. I feel like if I can get a faster machine that will cut grass 2 days a week I'll be okay. Specifically I've been seeing used Cub Cadets, 22 hp 50 inch cut. Know anything about them? I'd be interested in hearing opinions from people who've used them.
