I finally took the plunge and bought one. It has been a brutal winter here, north of Barrie Ontario. Thanks for all the valuable info at Tractorbynet. I was a little more informed and confident when I made this purchase.
The 50" (not heavy duty model) blower eats through ice and snow effortlessly and traction is great, even blowing up hill with the turf tires.
One minor "beef": a linkage connected to the AUX valve (up/down) is bent. My guess is the overly long AUX valve lever was hit in shipping or assembly. I am so tempted to cut off 3" and re-thread the lever end.
