What is the best choice for your first mower and why? I am currently using a 48" scag WB. I have not been using a sulky, but I know that it would increase productivity once I got use it. My problem is that this mower is a loaner and I will need to purchase a mower for next season. Should I get the Scag Zcat 42"? I realize the type of yards I mow is a deciding factor. Most of them are small residential lots 1/3 - 1/2 acre. I plan to expand my business on the residential side first and then begin a few commercial accounts. I want to get the most for my money in terms of longevity of equipment vs price. Do walk behinds offer longer trouble free life vs small ZTR's?
