Fox Ridge ranch The one thing I can say is you have a great horse!
You have adjustment issues with your cart.
I can help you to a point hooking up your horse and adjusting you harness. You are in the middle of midwest driving USA. It would be best to join a club or find a mentor to help you with the finer points of harnessing and driving.
Every adjustment on a harness affects other adjustments so it is a bit of a complicated process.
SO THAT SAID: This will probably be several posts with you adjusting then taking photos. Posting, then adjusting again. So if you are up to this so am I.
My main question is why do you not have a bridle? Are you planning on driving in a halter? I would not recommend this, as this is highly dangerous, and it is not IF but WHEN a serious problem will occur.
In the American Driving Society rulebook, is says ..Removal of the bridle while the horse is still hooked to the vehicle, the driver will be eliminated from any event and in some instances be asked to leave the property. I am paraphrasing, but you get the idea.
So back to your harness;
#1 Put on a bridle! Blinkers or not, Put on a bridle. At all times while harnessed and while harnessing have a bridle on, I can't stress this enough.
#2 You horse is too far back in the shafts. The shafts are supposed to end at the point of the shoulder. Reason, shafts lto far forward will hit the horse in the face/head or neck when the horse turns, causing discomfort and counterbending, a no=no. And his rear end is too close to the cart.

I put the cart up to the horse, put the shafts to to the shoulder the attach the traces. If the traces are to short figure out how to make them longer or buy longer ones. There is no negotiation here. Shafts can be a bit short but not a bit long.
This will bring your horse's rear end further away from the cart. Where he is now, there is no way his hind legs wont hit the cart, causing all but the oldest and kindest soles to kick. And you can't blame a horse for kicking if every time he takes a step his hocks hit the cart..
There are several more adjustments to make then maybe you can implement those adjustments, take a photo and then we will see what other adjustments need to be made.
I will try and post again this afternoon, I am having company this evening and need to clean house.
I just wanted you to know I will give you a hand.
