I am currently mowing 5 lawns, all of them are less than one acre. I am mowing them with a garden tractor and the deck is beginning to rust through on the welds. I will have to purchase a new mower before next season at the latest. I plan on expanding my business and was planning on buying a used commercial walk behind. There is a Scag dealer very close to where I live so I'm thinking about getting one from there. I can't spend any more than $1800 on a mower. Any suggestions?
