We have two models available, there is a trailer for two rows of bales and the other version carries three rows high. The trailers can be used for round or square bales, the important point is that the retaining arm must be at least half way up the bale to keep it securely on the trailer.
When using the trailer you do need to stack the bales neatly, the frames are not there to be used to tidy up a poorly stacked load. When the bales are loaded you just raise the frames to hold the bales in place and that’s it ready to travel. It is much quicker and easier than using straps; it is also safer, no one needs to stand near the unsecured bales as you would when using straps. It is important when you unload the trailer that you stay clear when the frames are lowered in case any bales have shifted during transit as they may fall.
