It's not designed to do those things and that's going to present you with some big problems.
You will need to remove the deck, and mower drive.
You are going to have a tough time lifting the blade with the mechanical lift.
You would have to make the blade and mounts yourself as none are made for this model.
The lack of weight is going to fight you all the way through the process, weight = traction, your model is half the weight of the model that offer a blade for.
Your model is also much lower in HP that the models that they offer a blade for.
IMHO, You would be much better off if you are going to do anything, would be to mount a snow blower to the front of it.
A self powered model would make it easy to do without a whole lot of negative effects.
