Russ,
Ah, I see the problem now..
I suspect you aren't exactly aware of how "snowblower model years" work..
no biggie, it took us all (on this forum) awhile to figure it out..it can be confusing.
Here are some details:
https://scotlawrence.github.io/ariens/Page11.html#question6
So in the case of the particular snowblower model we are talking about, it was made over three model years, 2002, 2003 and 2004.
The individual snowblower in the first post in this thread can be one of those three model years.
2002 model year:
The snowblower was made in mid-2001, went on sale in the Autumn of 2001 as a 2002 model year machine.
(when it was actually sold and first used is irrelevant.."how many years old" is based on when it was made)
The Autumn of 2001 was 17 years ago.
2003 model year:
The snowblower was made in mid-2002, went on sale in the Autumn of 2002 as a 2003 model year machine.
The Autumn of 2002 was 16 years ago.
2004 model year:
The snowblower was made in mid-2003, went on sale in the Autumn of 2003 as a 2004 model year machine.
The Autumn of 2003 was 15 years ago.
Current snowblowers being sold right now, regardless of their model year, is 100% irrelevant and has no bearing on any of this.
New machines made in 2018 are 2019 model year.
yes, many dealers can be selling new machines that are a year or two old..but that has nothing to do with how old the "2004" machine is..
thanks,
Scot
