I use mine all the time to maintain a long caliche driveway. I leave the boom pole on the tractor most of the time. Just back over the harrow, hook the chains, raise it up and take off (less than 1 minute to hook up). To cut the chain lengths, I lowered the boom all the way, then measured and added about 1 ft on each chain to allow some slack when the harrow was on he ground. These heavy chain harrows will do surprising nice work.
