JMHO here. A warm blade, impeller, chute - etc will cause snow to melt. The cold conditions will, eventually, cause this melted snow to refreeze on the blade, impeller, chute, etc. You now have a very rough surface. Snow will easily stick to a very rough surface.
Keep your blade, impeller, chute smooth with a fresh coat of paint. Keep the blower outside - lessen the chance for snow to melt on blower components. Beyond that - most everything else is a bandaid.
An example. You have your tractor and blade/blower in a heated building. Out you & the tractor go to move snow. Snow will initially melt on the warm metal parts. Quickly the blade/blower will reach the outside temps. Any/all melted snow now sticks to these cold metal parts. You now have rough surfaces - snow will continue to stick to rough surfaces.
