many tractors have a "front weight" bolt holes up in front. to accept a bracket, that holds suit case weights.
many tractors also have a spot were you can remove front "plastic like bumber" to reveal holes for a stronger front grill that goes in front everything. so ya do not inadvertently run a stick or like through the radiator.
both of the above things should be coming directly off the frame.
looking at images i pulled up via google for your tractor, it kinda looks like a U shape bumper that got squashed into a T shape. you might be able to undo some bolts. and pull that off, to slip a better DIY frame up and onto the front. for a receiving hitch.
instead of just welding a ball hitch on and/or a couple nuts in place so you can screw a ball into for different size balls. i would say if ya going to take some extra time, might as well go with a receiving hitch. like back of trucks, so you can change out to different things if wanted. from lower drop hitch, to a straight hitch, to possibly some sort of "mini rack" that folks can buy to hold a couple bicycles or some coolers for camping trip. and just slide that right into the receiver on the front. some folks have went extra step of getting a 12v electrical winch that slides into a receiving hitch.
