I was recently laid off from my full-time groundskeeping job at a local university and now I'm looking at maybe starting up a lawn mowing business after a few suggestions were made about it. I'm used to Commercial mowers, we had three John Deere 997 72" and 4 other commercial mowers when I was working. Obviously there's no way for me to afford an $18,000 mower. Even the low end JD 700 series mowers are pushing the price even though I know they're worth it. I'm trying to keep my initial start up expenses under $10,000 so I've been looking at what they call Semi-Pro mowers, in particularly the John Deere Z425 54" mower. What are your thoughts on these kind of mowers? Are they durable enough to handle a small commercial business, but also durable enough to mow 15 acres in a day on one job? I was looking at trying to secure the mowing contract this year with our local school system, which is generally around $12-$13,000 a year for the three separate schools.
