Choose the HB511 if...
The wider step up from the HB506, for larger horses or owners who want more room in transit. The extra 12cm of internal width and 36cm of length cost 80kg unladen, which is worth checking against your tow vehicle before choosing it over the HB506.
Full specifications →Choose the TA5 if...
The standard British livestock trailer, and the one most smallholders and farmers picture when they say livestock trailer. Low loading height and flexible partitions matter more here than raw capacity, because the job is getting animals in and out calmly rather than maximising a payload.
Sold in three lengths and two heights, plus heavy-duty versions at a higher gross weight. Figures above span the range rather than describing one trailer.
