the type of shafts wo,nt matter,but until your horse gets used to the cart wrap rags around the ends so if he turns sharp they wont dig his side make sure the shafts are fairly snug against her so if she kicks she is less likely to put her leg over,wen i put a horse in a cart the 1st day i tie it up allday attached to the cart and during the course of the day lift rock and push the cart against him so he gets used to the feel of everything especially the breeching hope this helps |
