Trailing Shield for a Snow Removal Device

A snow removal device comprising:

• an auger assembly including a rotatable auger that imparts momentum to draw material engaged by the auger toward an ejection path, the auger extending substantially transversely with respect to a front portion of the snow removal device;
• a mobility assembly configured to enable the snow removal device to move with respect to a surface;
• a housing disposed proximate to a portion of the auger assembly to direct at least some of the material toward the ejection path responsive to rotation of the auger;
• and
• a blowback prevention assembly disposed to inhibit blowback of material between the housing and the surface, the blowback prevention assembly including a scraper bar and a trailing shield, the scraper bar being disposed transversely with respect to a bottom portion of the snow removal device and proximate to the housing and the auger assembly, the trailing shield disposed proximate to the scraper bar and rearward of the scraper bar,
• wherein a longitudinal length of the scraper bar extends parallel to a longitudinal length of the trailing shield, and a portion of the trailing shield is affixed to the scraper bar, and
• wherein the trailing shield includes an attachment portion and a skirt, the attachment portion attaching the trailing shield to the scraper bar and extending substantially rearward relative to a front of the snow blower, the skirt including an arcuate curve that bends the skirt at least partially toward the surface.
