Greetings...
I did a google search..and found that the deflector extension isn't for throwing snow farther, but to keep the snow a little further away from the operator of the snow blower.
An old Husqvarna (2008 brochure) stated that...
"When winter delivers a dry snow and breezy conditions, clearing
your driveway and sidewalk can be unpleasant experience if you end
up covered in snow. LS snow throwers are equipped with a rubber
deflector extension to help keep you warm and dry while putting
snow in its place."
Regards.. Dan
