A trail grooming question

A trail grooming question

Post by Dan Kari » Wed, 23 Feb 2000 04:00:00


I've been grooming a 5k loop in our trail system with my Skandic WT and
a home-made drag. When we get a good dump(say 1 ft), I have to go around
with the Skandic first to get a decently firm base. Because this trail
is not that well graded and some turns are banked downhill I've been
making the first pass on the uphill side, thinking that I'd work the
snow downhill and level the track. Instead, what seems to happen is that
the sled wants to tilt downhill on the next pass and I have a hard time
keeping from divig into the powder. Question. Is it better to start on
the downhill side, or in the center or?
        I do realize that one rides the sled like a horse-no sitting and just
turning the bars!
Thanks, Dan

Hmmm...
That is a good question. It depends on many factors such as snow
conditions and type of drag. I have a knee-jerk response: is it possible
that your drag sinks to lower elevation in powder than it does on first
pass surface? In other words: you make a first pass. Then, on the second
pass, your drag has one side on the *** snow and the other side on
the first pass surface. If the drag penetrates deeper into the powder
than it penetrates into the first pass, then it will tilt even worse
than intended into the powder. You, being intimate with the conditions,
can probably quickly accept or dismiss this explanation. If this is
possibly the cause, then yes, try grooming the outside first. However, I
always preferred inside first, when drag-grooming, due to the drag
following to the inside on bends.

I have a grooming wing that is affixed semi-rigidly to the snowmobile.
By leaning and tilting the snowmobile when grooming powder, I can
super-elevate my turns, pretty cool. I designed and built a drag that
had dual remote controls, one for the left side and one for the right
side of the drag balde. That way, the customer could adjust, on-the-fly,
the tilt of the blade. He wanted this capability for side-slopes and
banking turns. That was too cool (too cool for most budgets).

There is always the tough-guy method. After a foot of packed snow has
built-up on the trail, get out there with a shovel, and hand-shape that
turn with super-elevation. Cut snow from the high-inside and dump it on
the low-outside until it builds-up to desired shape. Typically, you only
have to do this once at the beginning of each season.

Good Luck.
