Round bales and three point hitch on a M

Have picked up 5x6 bales with the one I had on my 460. The person that purchased my 460 started to use it dailey to move bales and he broke the hitch. poor welding job at the factory. He had the local welder. Weld it back up a beef it up and now it works good.

Basic math, if the weight of the bale plus bale spear is less than the capacity of the hitch, you can reasonably expect things to be okay.

Of course, like old says, there's that matter of the front end coming off the ground... Add-on 3pt hitches stick way out in back of the tractor, giving the bale that much more leverage to tip things over and make life miserable. You'll probably need front end weight.
