I have never used an inverted blower so this may not apply.
We get some heavy storms here from time to time. One thing I have found that helps get thru the deep snow is to hold the blower off the ground 6" to 12" depending on the overall depth of the snow and consistency of the snow. That applies more weight to the back of the tractor so you can cut your way thru the deep snow. Once you get a path cut thru then go back and clean what was left.
Quite often if snow is building up in front of the blower it is an indication you are going too slow. Raising the blower will reduce the cubic feet per minute of snow you are blowing so, depending on conditions, you can increase your speed so you out run the snow building up in front of the blower. Each blower/tractor combination will have it's ideal cubic feet per minute but that will vary by snow conditions. The deep storms challenge us to find the ideal setting for blower height and speed to efficiently get the job done.
And sometimes we get that rare storm that doesn't have an efficient way to get it cleared so we just muscle through as best we can.
That does apply to inverted blowers Reb954. I did that this morning while clearing my neighbour's driveway. Yesterday the snow was very dense and I had conditions similar, but not as deep as Hillbilly's. I plugged the blower similar to what Hillbilly describes three times. I finally was able to keep it going continuously by regulating the intake via the tractor's speed. I went down to another neighbour's to clear his yard for the annual New Year's Day party they have for our road. He has an 82hp, 4WD Ford 6610 with a rear blade but I end up clearing his place at least once a year because it gets too much to do it with his blade and bucket. The area I cleared had over 2' of that heavy, cement-like snow. I tried it going forward and could have done it but I could tell I might wreck something. So I did the first pass(it's only 100' long) by backing up and pulling ahead. Once I had that channel open I could do it all in one pass.
They have not cleared our road and only 4WD trucks can manage it. So neighbours walked down to get to the party and my one neighbour and wife drove down on their tractor. I put concrete blocks in the truck and was able to drive. But we left before dark in case we got stuck coming back home (an uphill drive). It was fine but if we met another vehicle we likely would have both been stuck as we could not pass each other.
Yesterday I was unable to get to one neighbour's(it is where the photos earlier in this thread were taken) I always clear because trees were down over the road. So I did a couple of passes for two other neighbours' on the way home.
Today it was -3 C and someone had cleared the downed tree. So I was able to get to the neighbour at the end of the road. The colder weather made a big difference. The snow was likely as deep but so compact that the tractor was likely 3" or so higher by driving over it, making it only as deep as the top of the front axle. I had to raise the blower to do the first pass and after that I could take the full depth. In all I did three passes over the whole area to progressively shave off the snow.
I realise inverted blowers are not the right choice for everyone. However, each year I am more confident they are the best choice for my situation.
Our storm was not as dramatic as Hillbilly's but we must have had at least two dozen momentary outages in the last few days and a few lasting 1/2 to 2 hours. They are cause by snow-laden limbs falling. Most of the snow is off the trees now and every thing is stable today. But the road people have still not cleared our road. No doubt they are busy with the main roads. We are a class "D" on their schedule!
