my mini carts with a halter and reins and no bit
Yes it is possible to cart without a bit they do not make halkamores for cart but you can do what I do and use cart reins and a halter I first broke my horse with a bridle and bit this is just to teack him the basics you want to lung a lot to teach your horse to obey your commands too...It is possible and you have to remember that but I hardly suggest ground work and keeping it safe, I have been to the ER for a cart accident before so yes just because it looks safe doesn't mean it is. The best way your horse will trust you is by letting them know there is a big cart behind them because it is a little scary having something follow you around and not know what it is. So you want your horse to be fully aware and OK with it. If not try teaching your horse that it is harmless.
