More irrigation, now on the second pass of the first 60 acres of spuds that we planted, followed by changing more fuel hoses on our tractors, this time it was the 6810 and 6420s, last week it was my 6920s that had every single rubber hose changed. My guess ,which is now also supported by our dealers service manager as they too are seeing more hose problems than usual, is that the additives in the higher quality diesel introduced this year are eating away at he hoses on tractors and in the case of the 6920s the filter seals as well
