The above slide show is of the photos recently uploaded to our SmugMug site showing the packer attachment. I’ve included a lightened version of the photo to make the packer more visible. Click the slide show to see the gallery in SmugMug. Perhaps our TrailMaster will add some comments on how this interesting attachment works. It appears by the photos to be designed to pack the area between the tracks. There are leaf springs that apply pressure to the snow as well as a hydraulic cylinder that allows adjustment from the driver’s seat or lifting the packer all together. Are the leaf springs steel or fiberglass? What is the packer material that contacts the snow? It looks like a flexible plastic or rubber. Very cool. Thanks for sharing!
