That is not correct. That is a King Kutter or if it was bought at Tractor Supply called something else. AK, you are correct that the bolt hole in the bottom is suppose to have a bolt with a sleeve on it. The metal stud on the hitch is suppose to go in front (tractor side) of the bolt with sleeve. The top link should be on top, thus you must extend the link out quite a ways. Looks to be a Kubota tractor. With these cutters on a Kubota not unusual for it not to lift very high, especially for loading. Most Kubotas have different holes to hook the linkage to the tractor. Use the bottom hole for higher lift. If you need pictures I have one hooked to a Kubota now.
