I looked at all of the triple axle gooseneck dump trailers before deciding on the iron bull. So far I’ve hauled over 200 tons of 1 1/4 minus and numerous odd loads without one problem. The only gripes I have are that the rear supports for loading equipment would be better if they were a swing away style so you can back up to get them out of mud once your loaded. Second the tarp ratchet design and jack handle holder are an embarrassment to the rest of the trailer, they look like afterthoughts. Great trailer otherwise has no problem with 8 ton and piles great.

I have a few issues with the trailer. I’m registering my warranty now. If these are addressed in a satisfactory manner then I’d be at 5 starts.

Was looking for a dump trailer to haul our skidsteer. We were having trouble finding one rated for the weight we needed until we found this triple axle. Just what the doctor ordered and from what I can tell everything was made in the USA like it should be!

With a heavy hauling 83" x 16' triple 7k axle for a total GVWR of 21,000 lbs., this configuration means business, and it's owners do too. It is perfect for construction, ag, or any commercial operation. 7k brake axles and radial tires provide a solid foundation for each Iron Bull dump trailer and ample grip for stopping power. A fresh coat of primer and powder coat gives each trailer a rugged finish with a showroom shine. Hydraulic cylinders are the muscle for each Iron Bull dump trailer with remote operated hydraulic pumps that feed the beast.


Made in the USA, it comes with lifetime LEDs, provided by TecNic lighting. All units are powered by a deep cycle battery as well. Each Iron Bull Trailer also comes equipped with a standard tarp kit, stake pockets, locking pump box, 5 position adjustable coupler, multi-function gate and 110v wall outlet charging receptacle for your battery. Our 83" wide 21k gooseneck is equipped with three cambered 7k electric brake axles and tons of standard features.

Did a lot of research and excited for my new Dump Trailer!
Sandy Adcock - 02/01/2021
We were moving to a new location and to get gravel delivered was $400 not including a load of gravel So we decided to look at a dump trailer. We looked at Big Tex and several other brands. Then we discovered Phil's Trailers and they had an Iron Bull 3 axel dump trailer. The construction looked to be better than the other trailers we had and the cost was less. The trailer was just what we were looking for.
