Abstract
A snow blower augers snow scrapped from a path to a fan. The fan is co-axial with the auger at one end of an auger housing. A fan shaft extends through an auger tube. The fan shaft is supported on one end by a fan housing bearing attached to the housing and at the other end by a bearing in the auger tube. The auger is supported at one end by a drive housing bearing attached to the housing and at the other end by a bearing on the fan shaft. This arrangement makes it possible to have an open passage for the snow to move from the auger to the fan.
