I really don’t know anything much about tandem, but I would imagine on a draft, you would want a tandem bar? Although, I also don’t know anything about full collar harnesses, so I would have no idea how to attach a tandem bar/leader bar to your wheeler.
With the miniature horses (lol, a LOOOOOoooooong way off from drafts, haha ha!) that I drive tandem, I have a set of trace extensions that are 14" long attached to my wheeler’s breast collar, at the shoulders, where the traces would buckle in.
the 14" of space between them, plus the length at the end of the traces gives what I think is the perfect space between them. When they are both working properly and in pace, the traces to the leader are slack, there’s about maybe 18" of room between the horses, and everything “jives” really well.
When they don’t work properly, and my wheeler slacks off, the leader ends up too far in front and pulls the traces taught, and there’s ton of distance between them. Or, on the opposite end of it, if my leader for some reason backs off (rarely happens), the horses get smushed together and my wheeler can (and has) gotten her leg over the leader’s traces. One good reason why a leader bar would work in my situation, so that hopefully wouldn’t happen, but I don’t have a good way to attach one.
Are you planning to show the draft tandem?
