Abstract

A gauge wheel for an agricultural implement includes a rim having an outer periphery and a tire mounted to the outer periphery. The tire includes an outer shell formed from a first resilient material and an inner core formed from a second resilient material. The first resilient material is harder than the second resilient material.

         8 . The gauge wheel of  claim 1 , wherein said rim has a hub and a web extending radially outward from said hub to said outer periphery. 
     
     
         9 . The gauge wheel of  claim 8 , including a steel bushing within said hub. 
     
     
         10 . The gauge wheel of  claim 8 , wherein said rim is constructed from one of machined metal and molded plastic. 
     
     
         11 . The gauge wheel of  claim 1 , wherein said agricultural implement is an agricultural seeder. 
     
     
         12 . An agricultural implement, comprising:
 a tool bar; and   at least one row unit carried by said tool bar, each said row unit including a furrow opener arrangement with a gauge wheel, said gauge wheel including:
 a rim having an outer periphery; and 
 a tire mounted to said outer periphery, said tire including an outer shell formed from a first resilient material and an inner core formed from a second resilient material, said first resilient material being harder than said second resilient material. 
   
     
     
         13 . The agricultural implement of  claim 12 , wherein said first resilient material has a durometer rating of between 80 to 100 durometer, and said second resilient material has a durometer rating of between 20 to 40 durometer. 
     
     
         14 . The agricultural implement of  claim 13 , wherein said first resilient material has a durometer rating of approximately 90 durometer. 
     
     
         15 . The agricultural implement of  claim 13 , wherein said first resilient material is a first urethane material, and said second resilient material is a different second urethane material. 
     
     
         16 . The agricultural implement of  claim 12 , wherein said outer periphery of said rim includes a first keying feature, and one of said outer shell and said inner core includes a second keying feature, said first keying feature and said second keying feature coacting to hold said tire on said outer periphery of said rim during operation of said gauge wheel. 
     
     
         17 . The agricultural implement of  claim 16 , wherein said first keying feature is a recess in said outer periphery of said rim, said second keying feature is a projection from said inner core which is positioned within said recess. 
     
     
         18 . The agricultural implement of  claim 12 , wherein said rim has a hub and a web extending radially outward from said hub to said outer periphery, said outer periphery including a first annular recess and said outer shell of said tire including a second annular recess, said inner core positioned partially within each of said first annular recess and said second annular recess. 
     
     
         19 . The agricultural implement of  claim 12 , wherein said rim has a hub and a web extending radially outward from said hub to said outer periphery, and wherein said hub, said web and said outer periphery are integrally and monolithically constructed together. 
     
     
         20 . The agricultural implement of  claim 19 , including a steel bushing within said hub.
