Fairly simple! The Gleaner owners have a simple machine to maintain and repair, and normally do the repairs themselves saving lots of shop$$$. And they are willing to share their knowledge sitting at their computers with the coffee and NOT the daily dealer Coffee Time Sales Pitch of how much better or that they need a new machine every year or two. More than half of the posts are on over 10 year old machines and quite a few on 20 to 30 year old machines. Not many Pre-Rotary questions on the CaseIH site and not many on the Pre-Titan II series at Deere. New Holland site tends to have quite a bit of activity on older machines too. This leads one to believe that the Gleaner and New Holland machines are build for longevity, not for ROll OVER programs that within a couple years you need a different machine(PlANNED OBSOlESCENSE),or they are too complicated for the owner to diagnose and fix. And yes, it does seem that Gleaner owners are more mechanically inclined. In many cases the owners do what the factory doesn't seem to want to do to take a high capacity machine and increase its capacity considerably. Deere and Axial Flow owners can not take their machines and tweak them and get that much of a boost out of them. Gleaner builds on the Conservative side and the owners tweak to Maximize the machine. The AF and STS are built to maximum with little to no room for extra capacity or service life. Does this make Gleaner a better machine, that is to each their own opinion. My 20 year old Gleaner will not be beaten by the largest or newest AF or STS and still at minimal maintenance cost each year. Not bad for an OlD MACHINE in todays market!
