fallen snow.
- Smoothing heavily worn ski slopes.
- Smoothing bumpy ski slopes.
- Making a location line.
Material wear due to load!
During pushing work (i.e. when pushing snow with the front
blade), fully raise rear carrier plate.
A front blade is essential for modern ski-slope upkeep and
preparation. It is ideal for smoothing bumpy runs and pushing
snow clear. The front blade is also very useful for working uphill
through fresh-fallen snow and it can be used as a brake to
prevent the vehicle from slipping. Consequently, it is advisable
to leave the front blade installed at all times.
Smoothing bumpy ski slopes
The best method of smoothing low bumps or waves is to use
the front blade in what is known as the "floating" position. This
means that the front blade applies only its own weight to the
surface, without being pushed downward by the hydraulics.
The blade's angle of attack is set by means of the roll cylinder.
Exercise great care when setting the roll cylinder, because if the
angle of attack is too steep the front blade will tend to dig into
the snow.
Approach large bumps with the blade at approximately half
height and the float function switched off, so that the blade will
push the snow forward off the bump and into the hollow on
the other side. In this case, too, it is best to use the roll cylinder
to adjust the depth of cut, instead of raising and lowering the
front blade. This is the most dependable way of smoothing out
the slope.
The ideal configuration is to have a leader snow roller
mounted in front of the blade, as this will enable the equip-
ment to adjust automatically to compensate for surface
irregularities.
