Big Tex 25DU Tandem Dual Gooseneck Dump Trailer, Dump Trailers
If I had the need to haul my tractor to worksites (aka
paying jobs), with a single driver and a single trip, I'd look at this. Of course, since that would require a bigger truck, I'd probably keep the car trailer and buy a dump truck instead.
About the time I bought my tractor, I decided to buy a trailer to haul stuff to the landfill. I also wanted to be able to haul my tractor, and stay within my budget. This led me to a 16' landscaping trailer - basically a car hauler with sides and a ramp tailgate. It was a very capable trailer - hauled the tractor a few times, two cords of firewood, two cubic yards of gravel, a load of 16' composite decking, and many loads of tree trimmings and brush to the recycling grinder.
And then, due to a health issue, I decided to work smarter. I bought a grapple. When the spring cleanup season started, I got a ton of work done with much less time and effort. I was also able to load the trailer with brush and branches quickly, and pack it down into a tightly-knitted mass 16' long, nearly 7' wide, and about 4' tall. Easy peazy - until the unloading part. I took SWMBO and a small chainsaw with me to unload, and we attacked the load from both sides. Had to cut the loaf into manageable chunks and tear it apart to pull it out. About ten minutes in, the wife snapped off a branch she was pulling on, and fell. She landed on her thumb, spraining it badly. She sat in the truck with a cold pack while I finished unloading. When I got in, she informed me that a dump trailer was in order.
I bought a 12' from Sky Trailer manufacturing. The 16' landscaping trailer was now obsolete for my uses. It just went to work for someone else, paying for a substantial portion of the dump trailer. I am completely happy with the ability to dump the load without touching it.
