I am considering purchasing a used easy entry cart on craigslist for my standardbred mare. My girl used to race and now has some back and stifle issues that currently prevent her from carrying a rider at more than a walk. I talked to my vet and wanted to try pleasure driving with her since she lunges and ground drives at the trot just fine without a rider, so I am looking for a cheaper cart to test this out with her. If it works, I will likely upgrade, but I want to be sure I am getting an appropriate sized cart.
Anyhow, my mare is 15.1 H and wears a 72" size blanket. The seller lists it as cob size with 72" shafts, but to my novice eyes it appears they are not measuring all the way back to the singletree. Is that how cart shafts should be measured? I was using this website as a guideline: American Driving Society
Here are a couple pictures from the ad:
Thank you in advance!
