we have harvested about 1500 ac of corn and about 600 ac of beans with our 7010 and have had a list of problems with the combine. first we have had to fix the feederhouse chain 4 times at about 3-4 hours of labor a time also have had the draw bolts the keep tension on the feederhouse chain break 3 times. we have had the unloading auger chain break about 5-6 times. we have had problems with the fuel filters and have had to change them 3-4 times in the last 2 weeks. The most recent breakdown came 2 days ago when we had the fuel tank expand so far that the tank pushed itself into the clean grain elevator pulley and puncture 2 holes in the tank and lost about 200+ gallons of fuel. also the walkway above the fuel tank has also has a bow in it. we now are scrabbling to beat the snow with about 450 acres left to do and the dealer has brought us out an 8010 to work with until they get the tank on the 7010 fixed. has anyone else had as many issues with these combines as we have?
