I have a chance to purchase a toro 217d 52" that has been well maintained. with a blower kit on it as well, I have offered $800 for it but I was wondering if I should spend my money on a zero turn. As of right now I have mostly larger commercial accounts that have over an acre to mow and I currently mow them with my walkbehind (kinda sucks but its excercise). Don't know if its the best investment especially when diesel goes to $5/gal. Any thoughts?
