G1800 G1900 Snowblower & 3-point availability

[jas67]

I am contemplating the purchase of a G1800S. Are the snowblowers for these readily available? What model snowblowers will it support.

Also, what about the 3-point hitch? The one that I'm looking at does not have the 3-point hitch, but I may want to add it.

Thanks,
Jay
