I only am cutting with a 21in now and am wondering what is the next size u guys think I should get. Most of my current customers are 1/8-1/4 acre lots. I'm thinking a 36 wb would be the most logical and affordable choice as I could use it to cut back times on most existing jobs and if need be could use my small 21 as a back up. Of course I'd like to have a 48 or bigger Z, a 36 and 48 in wb, and big trailer, but all that would be over 10 grand and I'm having to probably finance this so I'm trying to keep in as small a debt as possible but yet still help me do my jobs faster as well as get me in a bit bigger neighborhoods. I have about 25-30 regular weekly-bi-weekly customers now. So would the 36 be the best first upgrade or should I go larger like a 42 or 48?
