If you don't have 4X4 on your tractor, you'll need some kind of counterweight on it. My unit weighs nearly 1000 pounds and when it is in the air the rear tires spin rather easily. Plus, the 4X4 will aid you in coming to a stop when you apply the brakes. You'll have to slow your ground speed down a bit for the deeper or heavier snow falls. And, beware of depth perception - the item are closer than they appear. I know I'm probably preaching to the choir but, before the first snow fall, walk the area where you'll be operating the snow blower. You'll be surprized how far a stone 4 inches in diameter will travel through the air. It scared the begeezums me.
Also, this is for everyone who is reading this - if there is an obstruction in the shoot or any problem at all, please, SHUTDOWN THE SNOW BLOWER AND TRACTOR before you service the unit. I know it is a pain in the back side for a 30 second problem, but it takes only a split second to lose fingers or the entire hand. In my previous life as a medic, every winter we answered at one call where an individual attempted to clear the shoot of obstruction - well, the end result wasn't pretty. Roger
