I have a larger blade on the front of my smaller tractor.
I usually keep it tilted to one side and plow in smaller bites (5-6" snow and I start).
Do you have a lot of turns that have slope or are angle down?
Are you on any steep sections?
What tires do you have on it?
I have R4 tires.
To keep the blade above gravel you can use Edge Tamers, which are like little slides that keep the blade a bit above the solid (gravel).
