I have a Woods SS-60 that I use with my B-7500. I have used it for two years with little or no problems. I have blown deep enough snow to bog it down and have had to stop and let it catch up with the amount of snow in the auger, but that isn't something that has happened often. Actually, the more snow on the ground the better it seems to blow it!
Not sure where you are located and just how much snow you have to deal with. Around here the blower works fine if we have more than six inches of snow. Less than that it seems to be harder to clean it up with the blower.
As mentioned before get one that is at least as wide, maybe a few inches wider than the rear tires on your tractor. This past weekend I did around 2200 feet of driveway, plus blow out four different place. It was only about 10 inches of snow, but with all we have had this year I am sure without the blower there would be no place to put the snow.
The ideal setup (that is if you don't have a front mounted snowblower and heated cab) is to have the 3pt hitch blower and a power angle snow plow in the front to first push the snow and then use the blower to blow it off the edge of the driveway. Next seasons project!
