HOW DO YOU KNOW IF A CART IS OVERLOADED?
Small pony (11-12hh) – a maximum of 600kg
Medium pony (12-13hh) – a maximum of 750kg
Big pony and horses over (13hh) – a maximum of 1000kg
The above mentioned guidelines include the cart, passengers and load. If you are unsure, the easiest way to tell is to watch the horse start or stop the cart. If the horse struggles to pull away or stop it with ease, then it is most likely too heavy for the particular horse!
