The sno-blaster was designed to solve the issues people have when snow grooming for fat bike trails. Some people use rollers to make snow trails for fat bikes.  Rollers do not take out moguls left by snowmobiles. A roller is better than nothing and is often used when people have not yet heard about a sno-blaster. Taking out the whoops is key for fat bike trails. If you leave the whoops and just compact them the up and down will make you ride much slower. 

In deeper snow and especially in deep powder running a groomer or roller will have the snow falling back into the trail. The wings on the snow blaster can push back the powder that would fall into the trail.  It even leaves it at a reasonable angle and not a 45 degree which just lets the snow fall back in. Wet snow that falls back in and then freezes leaves frozen snowballs that become hazards on your fat bike trail. Even when you pick up the blade so you keep the snow. A picked up blade can still take out big drifts and not just pack them into speed bumps. 

When riding fat bike trails there can be ruts left by the bikes themselves. Especially when the trail is ridden when it is warm enough to be slushy. The blade can cut down and fill in the ruts.  A really rutted up trail from slush and then frozen is not a fun trail to ride on.  Snow Grooming For Fat Bike Trails is made easy by the

One more key thing is that you can regroom your trail with the blade up just enough to remove no snow. But it will remove the excess snow from places where snowmobiles cross your path, pushing snow into the trail and leaving good bumps or jumps.  Or where drifts are made just by blowing snow.

Being able to add weight into the pan of the sno-blaster can compact the snow to the right consistency.  The design of the sno-blaster is such that it can take a beating over the years, take care of fat bike trail needs and leave nice smooth corduroy to ride on.
