That's the same blade and width I have for my HN2120. I have used it a bit and have not hurt anything. Last year I was pushing back side snow banks in a customer's driveway. Caught a stump on the outer edge of the cutting edge. Spun the 2120 around like it was a Tonka toy and made some real nasty noise. I thought I must have really broke some thing. Got out and looked... nothing. I mostly got my blade to work in dirt (grading, leveling, ditching) Sometimes I think moving snow is harded on the equipment because you speed is a little faster that it would be if it were dirt.
Almost time for another get together? I may have missed the last one, been a very busy fall and winter holidays.
