This is my first year snowblowing. I had never snowblowed with anything ever in my life but I knew the plow truck wasn't working for me. I ordered a Pronovost Lynx 70" this fall. It is a great blower & from right there in Quebec!
I have the manual chute rotator on mine. It is the best design I have ever seen but I think I will eventually go with some sort of powered rotator 1. because I plan on making/buying a cab before next year & 2. Because it is kind of akward to turn the crank handle with the blower is down on the ground (bad ergonomics).
It has been a learning experience for me as I have snow blown: dirt, a snow shovel, a wooden pallet, about 25 rocks 1" to 2", & a 5" rock.
I broke 5 shear bolts so far (pallet, shovel, & 5" rock)
I have 1000' dirt driveway. Same thing others said as far as technique, tips, etc..
The Lynx doesn't have adjustable shoes so I made my own for mine.
I want a cab BAD,...mostly because I has a nice heated cab with my plow truck & gave that up for the tractor & because I often owrk out in the cold at my job so I want to be warm when I'm off the clock.
If I were you I'd order a new Pronovost Lynx blower as wide or wider than your tractors rear tires. Made some sort of adjustable shoes for it for next winter (won't need this winter). Buy a cheap snowmoble helmet, a insulated coverall suit, super warm boots, mittens, etc.
Before you pay for your blower check it all over good. I love my blower but they messed up on the auger as it is off by about 1/2" so when you set it flat down on the driveway it goes "whomp,....whomp,....whomp.." as the auger drags on the ground in that one spot.
Good luck & God Bless
