Re: 44" snowblower for X320
I would not grease the bottom of the chute or the outer teeth. I did this last winter thinking it would help displace the water (from melting snow) and keep the chute from freezing up. What it did was cause the sand/dirt to stick to the grease and make a mess. Best thing to do (I've found) is remove the few bolts holding the chute to the blower head and wipe down both surfaces. When you are done using the blower, leave it in the up/lifted position. This will help the water run off the blower and not puddle and freeze under the plastic chute.
