Buy or hire the Portax K if...

- you want one that is 22cm wider inside
A mid-range Portax with a front unloading ramp, bought by owners who value being able to lead a horse out the front rather than reversing it out. It sits below the Big Portax models in size and price.

Buy or hire the TA5 if...
- you want one that is rated 300kg heavier gross
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.
