Seven forage trailers took part in our big comparison test. Our focus in part one is on payload, unloading speed and running gear.

Tipping trailers do the vast majority of silage carting in the UK and Ireland, so why are we testing seven different makes of forage trailer? These trailers with a moving floor have two key advantages when compared with similarly sized tippers: for starters, they don’t demand a vast amount of take-out oil; and, secondly, they are much more stable when unloading.
