You have probably seen Teamdonk’s new Modified Breeching.. if not go back to https://2014teamdonk.wordpress.com/2014/10/29/the-modified-yankee-breeching-is-done/ to see the breeching transformation. That was my first #1 fall project.
I am so excited about this next upgrade I can hardly stand the wait before hitching again! Our newest edition reminds me of the famous Cape Cart. This design of a two wheeled cart for pairs was a huge success across several continents. Take a look at where the single trees are mounted on this Cape Cart.
Part of why this cart was such a superstar in its day was the unique method of adding a pole across the front of the horses that was a part of the harness. **Please Note** this illustration is incorrect, I use it only as a general idea of how the cape harness looked.
The Pacific Gig is the most comfortable riding of the two wheeled poled vehicles that I use, unfortunately it was intolerable for the donkeys to pull due to their height and the incorrect line of draft when compounded with a collared harness.
To explore more on about this topic I highly recommend Barb Lee’s booklet entitled, “Understanding Harness Balanced Draft, Breast and Neck Collars”. Every driver, new or experienced, should own a copy of this detailed book. It is my harness driving bible.
This diagram is from Barb Lee’s book and demonstrates what I have been up against.
“Turnout D Horse is hitched to a high (Horizontal) draft vehicle with a neck collar. Acute angle between hame and trace will divert weight to lower third of collar, with little or no weight bearing above the traces. Very little body mass above the load. Traces are very high above center of draft. This is an inappropriate combination.”
Before I had the single trees lowered I researched the internet and my collection of driving books and was astonished to find newer CDE four wheeled vehicles with collared harness and single trees located near the top of the pole. Experience has taught me this was very inefficient and the line of draft was creating incorrect trace position on the collar which forces the top of the collar to rock forward. This made the teams want to back off and not push into their collars. The other ways to fix this was to change the line of draft at the collar with an adjustable hame or go to a breast collar harness.
Here is a photo of Hank hitched to the Pacific Gig with Merlin before the single trees were lowered. I printed this photo out and drew lines in where I felt the correct line of draft angle should be. That helped to determine the needed changes.
Now back from the welder the single trees have been dropped 11 1/4 inches by moving the pole braces, and rehanging the single trees. Here is how they look on the Pacific Gig looks now.

The shorter length breeching with the addition of the Yankee Breeching Straps that run across the top of the butt will really help Teamdonk to hold the cart back when cruising down our steep hills. Dropping the single trees on the Gig should make that vehicle useable again, I really cannot wait to test all our new upgrades and let you know if it is a thumbs up!
It really does take a great deal of engineering to attach two animals to a two wheeled cart. I don’t believe you can just take any two wheeled vehicle and attach a pole and make it work effectively out of an arena situation. The donkeys and myself love our Teamdonk off-roading adventures and 2015 is looking to be a terrific driving year, anyone up for a ride?
Happy Thanksgiving to all our Teamdonk Friends!
