I have an older Sears snowblower attachment model 842.260621
My research indicates it was manufactured by Haban Mfg. [subbed out to Topper] and that in 2000 rights to some Haban items were sold to Agri-fab but not the snowblower.

What models/brands of garden tractor would this fit?
It appears to be powered from a frontend PTO horizontal shaft pulley.

Sears and several others sold a combo mower /snow thrower back in the 60s and 70s. It used the same frame and engine but the mower and the blower detached. Haven't seen one? That's because these machine did not throw or cut well but what a great idea.

How do you change the belts on these units
