The breast collar needs adjustment. That's one reason Sarah isn't in the cart. If you look at the video on my website, the shafts don't go that far on him. With the breast collar on it wouldn't have so much play back and forth. He was only out for about 10 minutes on a level track. I knew the pic showed them long, but I didn't have another picture of him in harness. I'll keep your comments in mind the next time we hook him up.rabbitsfizz said:Where is the breast collar on that harness, is it hidden by the shafts?? He does look good but the shafts look a bit long for him, and are a trifle low, flat tyres or not (mine are flat and finished- need new tyres!!) if you adjust his position (Assuming he has got a collar on) he will find it easier to pull.
