Anticipate the terrain
Understand the terrain and prepare yourself for how the sled will react. If you’re approaching a hill on your right-hand side, for example, keep in mind that the snowmobile will want to lean down to your left.
Keep your eyes up & counter-steer
Your sled will naturally follow your eyes. If you look down, the sled will go down. Turn the skis down the hill, which allows the snowmobile to lean into the hill. Keeping your eyes up, counter-steer away from the hill.
Adjust your weight for balance
To help you get started and position your sled up against the hill, put either your left or right foot (depending on which way you’re leaning) forward on the running board. Hold your leg out for balance. This allows you to place your weight above the snowmobile on the top side of the hill.
You don’t necessarily have to hold your leg out. You can often ride in the neutral position with one foot on each side. It takes a little more counter-steering and throttle control to keep the sled on the hillside.
Use the throttle and brake for control
Burp the throttle, which will help raise the sled out of the snow and lean it into the hill. Use the balance of the sled and the throttle to control your trajectory along the side of the hill. Keep the position of your skis in mind. The further down the hill you point them, the more the snowmobile will lean into the hill and want to go uphill.
You can use the skis to push into the hill, which will stand the snowmobile up and let you go down the hill.
