I have one and it is a great snow blower. I paid $4500 for the blower, front hitch, drive line kit, and the Hydo chute roatation.
It is over built. very heavy. The SB52 blower will fit the 3100 and 3200 series tractors.
I have have had zero problems with mine, I have a 250' driveway with a large turnaround area, I also take care of my in-laws drive way that is about the same size.
I have had mine since 2011 still looks new.
Do you have a weight box for the 3 point hitch? If not you might want to get or make something. I have my rear tires loaded with Rim Guard and with the blower on the front it makes the rear a little light when the blower is up, so I made a weight box out of concrete and it made a big difference with rear traction.
