iMatch seems great, but when not in use it bounces around, is noisy, and seems to rub pretty hard against the tires. I see an s-shaped metal hook in the back, which looks bent. However, even if this wasn't bent I don't see how it could hook under the top link. My question: is there a way to secure the iMatch when not in use? For reference, I have a 2016 model year 2032 Tractor. Thanks.
