Combines Unloading capacity fuel economy

I don't know about the fuel economy but on n2 it sounds like it may be time to reflight the unloading augers or if they are fine you might want to put on a faster sprocket like the ones we run on rice machines.

I don't know for sure about 1688 series, but there was a huge difference between fuel consumption going from 1680 to 2188. I would consistently run along side 2188 with my 1680-when he went to fill up I would still have several hours of fuel left. This has been common complaint with many 21 and 23 seies owners in my area. as for unloading time, you definitely have a problem-it should not take nearly that long to unload. I have had experience with 1480,1680,2188,and 2366 -none of them had that prolbem even in 200 bu. corn.

You might check the slide pannel in the grain tank are up all the way. and if you have the 207 in. or the 2 piece
