The trail managers below have been kind enough to supply their techniques. Use a renovator to mix old and new snow. To pack 20 inches of snow in 2 passes you need a snowcat and tiller You need weight, slow speed, and snow preparation to set a good track. ATV winch on your snowmobile to lift tracksetters and winch your groomer back on the trail when you get stuck Arctic Cat Bearcats are liquid cooled but do not overheat like liquid cooled Skandics Bearcats steer better than Skandics Use a shear pin to protect your drags Install carbide studs for grooming on icy conditions Snowcat or Pisten Bully Grooming Pack track with your snowcat before tilling deep snow. Pisten Bully 160 with tiller, double track setter, etc.
Most grooming is done at night.
If the temperature is above freezing, we don't groom. Should the trail turn to hard ice, we are out of luck as neither the Tidd Tech nor the homemade drag will have any effect. Pisten Bully 160 with tiller, double track setter, etc. If the new snow is on top of old icy snow, we would power till the new snow into the old icy snow to mix it together. We only power till at night when the snow is frozen, not thawed.
