Precautions:

The deflection of the nose, the deflection of the nose will make the pressure of the two blades different. At high speed, a little deflection of the head will make the sled change greatly on the track. At low speed, excessive head movement will lead to serious speed slip loss.

When the foot touches the ground, the two feet will rotate in the direction of the foot that directly touches the ice behind. When both feet touch the ice at the same time, the sled can quickly return to the correct position during sideslip, but the speed loss is more.

Under the action of the curve, the curve of the track of modern steel snowmobiles will have an inclined slope, and the sled will go uphill. The second half of the sled blade is blunt, and there are grooves on both sides of the blunt blade, which can be embedded in the ice under the active pressure of the knee, causing resistance in the curve. In addition, the action of the shoulders can make the sled move up and down in the curve, usually with the action of the head and feet.
