I'm assuming what you described is a very common hay trailer in my area. They make both single axle "trailer" type and two axle "wagon" type. The ones I used were the wagon type and would carry five 5' bales at a time, and we would hook two of them together so we could transport ten 5' x 5' bales at a time. We'd load the bales from the rear and as you added a bale on the back end, just push all of them forward until we got 5 on. However, one guy in the area had a hydraulic hay handling device on the 3-point of his Ford that was not a spear. Instead of picking up a bale from one end, as you normally do with a spear, he approached the bales from the side and it had arms that clamped onto the ends of the bale, so he loaded the wagons from the side instead of the rear. His was the only one I've ever seen of that type. I never had any bales fall off accidentally although the guy I was working with had that latch come loose one day going down the road and dumped all 5 bales off into the borrow ditch. /forums/images/graemlins/shocked.gif You know it can be kind of awkward getting a tractor down into a borrow ditch to retrieve those bales with a Hay King bale spear on the 3-point hitch. /forums/images/graemlins/laugh.gif
