All Rangers can tow max gross weight @ 3500 # ( 2.4L 4 bangers can do just 2000#, a Z and the trailer ), they printed higher for newer model but they can't handle more than 3500 #. The small V 6 or newer 4.0 v6 is okay to pull a Z and a hydro WB, and 6x 10 trailer with equipment as long as they don't go over 3500. If you go over, your clutch will be very shortlived.
F-150 and up all the way if you want to do lawn service.
