Atv hitch cargo carrier

Hello I have a 2015 Polaris sportsman 570 touring. I bought a hitch cargo carrier rated at 300 pound for car but only 50 for atv. I wanted to use it to transport deer out of the woods. Witch would be roughly 150 to 200 deer weight and 27 pounds for the carrier. Now is it that the 1 1/4 atv hitch won’t support the weight or is it rated low because of smaller machines would be front end light. My touring is pretty big and heavy so I guess my only concern would be snapping the hitch. What’s your opinion. Thanks for the input
