Thank you for your question.
I have looked up both model numbers you have submitted. I am sorry but these two are not compatible. Being as this is a lawn tractor, you cannot mount a dozer blade onto it. If you are just wanting to plow snow you can use a snow blade on this tractor. The differences it a dozer blade is made to plow snow and push dirt and rocks. The dozer blade has stronger breakaway springs than a snow blade and is over heavier. I have checked the books and the snow blades listed for your tractor are 486.24443 and 486.24441.
Please let me know if you need further assistance.
