With this particular dolly what you do is back up to the bale activate the electric brakes then back up more until the half loop shaped frame is against the bale then flip the hook downthis will hold the bale in the frame while you pull forward with the brakes still holding until the bale comes over center and is fully seated in the frame for unloading just flip the hook up set the brakes and back up the bale will roll out then release the brakes and drive off to get another bale if that is what you are doing
