AK ... I use one and I have for the past several years ... Hay Buddy works best with your bales at 36" ... I may add that if your bales are not tight your right... it is a problem. I screw my wire tie baler down so darn tight its near impossible to get your fingers under a wire. If bales are twisted, bowed, C shaped thats a result of poor baler settings ...I guarantee you this is by far better than any pull behind accumulator 1.) No moving parts, latches, springs,gates to wear out adjust replace. 2.) If the baler misses a bale it don't plug the accumulator cause it aint right behind the baler. With this just go around the occasional missed bale...go back the next day and gather your missed bales with the JD Gator!!! With the pull behind you will stop and have to manually remove the broken bale.
The grapple has a sweep arm as you drive forward and to the left all gaps are closed between the bales and when you set 22 grapple hooks in by hydraulics they pull back tight and right. When you unload no chambers to wiggle down between the bales ... afterall they are so tight you can't get a hand between them let alone a chamber.
The stacks in the barn are square, level tight and do not fall apart or tip over. Sometimes I get asked "What does it do to the bale sliding it along the ground?" Simple ... it slides on the cut stubble not the ground ... if you believe you may gather dirt or rocks YOUR IN A FIELD THAT SHOULD NOT BE HAY MEADOW!!!
