I have a chance to buy a 33 inch Troy Bilt mower. I mow residential yards on the side, nights and weekends. Yes I have a business license and pay taxes, insurance etc. I only want it for a season or two until I can afford to buy a real walk behind. It would really help on yards I have been doing with my 21". I have read good reviews and bad, just like with most mowers. Troy Bilt is MTD now right? The guy is asking 600. No way I'm paying that much but what do you think I should offer?
