Those look like a good way to get your killin' done.
Hope you don't have any hills, or mud, or cows that like to come running when you're putting out a bale. So many ways to get hurt/killed with those things it ain't funny.
If you insist on doing something of that order, buy a $500 4wd pickup from the local classifieds and put a winch in the bed along with a hay spear that pivots where the tailgate used to be. More versatile, cheaper and safer.
