I am currently in a bind. Would a 5'x14' open trailer work out ok with a single 3500# axle? I figured anything over 12' would need tandem. I only have a 32" Ferris Hydrocut and 21" Toro Proline, but after reading the countless posts of people needing more than they originally thought, I'm thinking a 14' would be wise. I don't plan on buying a rider anytime soon, but maybe a 48" walkbehind eventually. But I figure I'd use the extra space for bags of fertilizer, spreader, tool box, etc.
