How many of you use Grasshopper mowers? I have a opportunity to mow for one customer, approx 4 acres. I want to purchase a 60" mower. I believe I can mow the whole thing in approx. 4 hours (not much to trim). The income from this job will pay for my mower in about 1 year. Is this a good deal? Then I would have a mower that my brother would like to rent from me for 1 to 2 days a week, and gererate more income. I don't want to quit my full time job, the money is too good!!
