Spreader with shaftless auger

A spreader comprising:

• a hopper for containing sand, salt or other granular material to be spread upon snow or ice on paved surfaces, said hopper being adapted to be installed in or on a bed of a truck, said hopper having a trough,
• an auger positioned in said trough,
• an auger motor for driving said auger,
• a spinner positioned at one end of said auger for slinging the granular material upon the snow or ice,
• a spinner motor for driving said spinner,
• a bushing secured to the other end of said auger, said bushing fabricated of a lubricious material, and
• a bushing plate secured to said hopper, said bushing plate including a spindle that supports said bushing.

• a spinner motor for driving said spinner,
• at least one keeper supported by said trough and extending over said auger for retaining said auger in place during operation and thereby reducing flexure of said auger and resulting loss of efficiency of material transport by said auger during operation of said spreader,
• a bushing secured to the other end of said auger, said bushing fabricated of a lubricious material,
• a bushing plate secured to said hopper, said bushing plate including a spindle that supports said bushing, and
