How high should I set the shoes on my front snow/dirt blade for the best snow removal results? Because I bought the tractor in April, I have only used for dirt work so far. I left the shoes all the way up so for dirt work, but I assume they should be down for snow work. Are the shoes there just to reduce wear of the cutting edge or do they somehow help in snow removal? Are they cheaper and or easier to replace than the cutting edge? It seems to me that I would be able to clear snow better without the feet down. What do you all think.
