I recently enherited a sears tractor model#917.25930 with a snowblower attachment model#842.260051 but can't find owners manual for putting them together I either need instruction or help find it

The Welcome to the Parts Store (http://www3.sears.com) should have a parts breakdown. This might help. The link MIGHT include a p/n for an owner's manual as well, but don't hold your breath that you can get it.

Try ayp.com ( american yard products) , this is who manufactured the unit for sears.

Model code 842 indicates the snowblower attachment was made by HABAN Mfg.
In 2000 Agri-fab bought out most of the Haban assets but they did not buy the snowblower part of the biz. Word is no one bought it so it was abandoned/scrapped.
Haban farmed out the actual manufacturing of at least some of its snowblowers to Topper in Racine WS, a company which I think is still in business.

As to the tractor, code 917 is for Roper Corp. (American Yard Prod.)
