Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I am looking for some help from those more knowledgeable than I. 
I was given a snowthrower as a gift a few years back.  I recent had a worm gear break preventing engaging drive. 

I am unable to identify WHAT snowblower I actually have as the serial number is rubbed off an illegible.  The only markings on the unit are "Spirit" and 1028, denoting the HP and deck size.  It has a Tecumseh 10 HP motor.

Can anyone help?

Thanks in advance.
