If you are worried about hitting rocks or trees then for safety reasons go slower. Our groomers have built in shear pins and bolts so that if you hit something then these break instead of your groomer or you or your towing machine. When not having these safety options you literally hit something and fly right over your handlebars of your snowmobile. Again safety comes before a good groom. There is also the case of our sno blaster groomer. It is fine to go faster as that allows you to blast the snow farther from the trail. The speed of a snow blaster is often 15+ mph if the trails allow it. If you are pulling a groomer with a tractor or other wheeled vehicle then a little faster can help cover your tracks as the razor cuts the snow on the side of your tracks. To summarize, safety is more important than how fast to groom your snow. Then not getting stuck and not breaking your towing machine or your groomer comes next. Depending on snow conditions the speed still may be different. How much weight compared to the density of the snow affects how fast you should go. Although in lots of cases a little slower than you think is OK. Experience is a great teacher on the speeds to groom your snow. - Snow Groomers: Nordic, Snowmobile, Fat Bike, Snowshoeing, Winter Sports
