When I was a kid on the farm, it seemed like every farmer in the countryside had that type of snowblower. And most all of them were "Erskine" brand, being that they were designed and made in the the town of Erskine, MN less than 50 miles from where I grew up.
The only issue I remember anyone having with them was after winter storms and if the snow drifted in so rock hard that the tractors would drive over the drifts rather than through them. Or the drifts were big enough that the tractor would lose traction before breaking through to the other side of the drift.
I happened to drive by one of their outlet dealers just a week ago and there must have been 50 blowers lined up outside ready for buying or shipping.
Not sure how they compare to other blower brands or pricing, but I'd guess their quality is on parr. They've been in business for around 50 years or more and still going strong and now make a few more attachments or equipment for tractors and the farming industry.
