The grass has been growing like crazy in my area and I'm looking to upgrade my mower. Right now I do about 10 yards every weekend with a little 21" John Deere. I want to get a 36" commercial walk benind with a sulky to get the work done much quicker. What can I get for around $1400?? I know I will have to buy used, but still want a dependable machine that stripes well. PLEASE HELP!!!!!!!! What should I buy?????
