Redneck version, useful if you don’t care exactly where the bale ends up, just the general vicinity:
Buy one round bale from hay supplier, have them load it in the truck so it can be rolled off. Drive into pasture, open tailgate. Drive a little way away from spot you want the bale to be. Stop, then back up at speed. Slam on brakes, bale will roll right out. :lol: An old cattle farmer taught me that.
I have learned how to do quite a few things with a round bale using a truck with trailer hitch, a long rope, and a hay hook. You can, for example, flip a bale up on end by burying the hay hook in the top edge of one end, then tying one end of the rope to the hay hook handle and the other end to the trailer hitch of the truck.
If you have the hay supplier load the bale in the truck sitting upright (on one of the flat ends), you can pull it out of the truck by tying one end of the rope around the bale and tying the other end around a tree then pulling forward in the truck. I’ve also used a cemented in gate post; if you do that, make sure you tie the rope right at ground level to minimize the risk of pulling the post over.
I can roll a smallish round bale on level ground (or downhill) by myself, but the potential for disaster is pretty high so you have to be careful. Don’t delude yourself into thinking that you can jump around to the front side and stop it from rolling away. Just because you were able to get it moving, doesn’t mean you’re going to be able to stop it.
It is also possible to push the bale across the ground with the truck, but I don’t do that unless I just can’t get it exactly where I want it any other way and I only need to move it a few feet. The bale doesn’t roll, it just gets bulldozed across the ground and makes a mess of the bale and the ground.
