What length of landscaping trailer would you have purchased 16 0r 18 ft. Enclosed or open?Also I currently have a 60" ztr but am going to look into a walk behind. What sise do you primarily use? Belt or hydro drive ? I am thinking of a 36" to get threw gates into backyards etc or should I go with a 48". Any suggestions.I currently run a stump grinding business and am looking into expanding into lawn care to supplement the down time along with using this to be on site looking for stumps? We also run a snow removal business in the winter. This information would be greatly appreciated.
