Where Does This Tube Connect To On My Lawnmower?

[ThatRandomGuy]

Hi, I have a Husqvarna yth2248 Riding Lawn Mower. When I was changing the battery I accidentally puled a tube loose from wherever it was and I can't find where to put it. I have looked at the schematics for the mower for a while and can't seem to find it there either. So I need someone to maybe describe to me where the part is supposed to go.
The link to the part is here: http://i1286.photobucket.com/albums/a608/ThatRandomGuyIsMe/IMAG0134_zps7d1fc157.jpg
Thanks in Advance

that is the breather vent line. should go in a hole on the back side of the air filter mounting plate.
