What is interesting with the 747 is that it was the only one built that big by Big Bud. The tires are special made and are finally in need of replacement. However, the Williams brothers are having fun trying to get replacements as these 8 tires are the only ones in existance that size. They are going to have to get some company to build them new tires for this machine which might cost a couple dollars.
As for the 80' field cultivator, when they are running it the shanks turn red hot. If I recall correctly they have to replace the shanks every few days as they wear out so fast.
Last, if anyone wants to see this tractor and go for a ride the Williams brothers are more then happy to show people the tractor and if they are working with it will let the people take a ride with them.
