If you have been there I want to hear from you. I plan to purchase a more productive mower this spring. What should I buy and why? I started business last summer, solo, with a 36 ExMark Metro belt driven WB with Mulching Kit and a Velkie. All my customers were residential plus one cemetary. My services was mostly mowing, edging, trimming, and blowing. Average mowing time per yard ranged from 30 minutes to 45 minutes. I want to double or triple my business over the next year. I plan to buy either a 44 Lazer ZRT or 52 Lazer ZRT or a 52 WB Hydro. If you have been in my shoes, please give me your advice on upgrading. I plan to keep my 36 WB. Thanks in advance.
