Cost? No real clue about small hitch stuff. Like the bigger stuff, I figger it will be all over the place and it will pay you to shop around and do as much work yourself. Also, HF has small, light trailers for around 2 big faces that will easily haul a 250/300/sumo and your garden tractor. Combine that with a coupon for 40% off and BAM! Cheap trailer. Take your time and do your homework here. Losing a trailer at 55mph will not be fun.
