Thing about the deal is it all starts at the header (front). This has become more evident as years go by and machines becoming so hungry. It is imperative that these are set up proper well before you blame the feeder or the rest of machine for it's performance. Us guys further north or south of equator know this best. Now some of us guys realized we had lots more capacity sitting idle in feeder house and beyond. You can read all about this and no matter how far we get we will still keep going forward as long as we are able. No matter how perfect the Gleaner design is and has been for 90 years the factory and farmers keep bringing it up another level. This isn't always easy with the hybrids coming along and many farmers diversifying into other crops. Thus some of us had to come up with aftermarket ideas and plans to fit an enormous amount of situations. No matter how you look at it I can't imagine any design that is so easy to switch between crops and do a great job in so many conditions as a Gleaner is.
