WhyIJ Because there are more 20+ year old Gleaners out there doing the yearly harvest than Deere! The first 3-4 years of N Gleaners had just as many problems as the current STS Deere. Gleaner refined their rotary in 3 years, Deere should be getting close on the STS too. I can't understand why Deere has had the problems with the STS with 20 years of several technologies to look at and learn from. I didn't buy my Gleaner for resale, I bought it for performance and design and longevity, it's twenty and quite healthy. I has yet to lose to the STS in any. The several STS's in this dealer area are increasing the sales of the Deere conventionals to the Deere diehards! One STS owner went lexion this Fall and smiling at the end of harvest. I don't know of one STS trade from the local dealer that went STS again, all went conventional or color change. Is the STS why Deere preached for twenty years that rotary doesn't workIJ Everybody else sure seems to have a good working design. And how many Deere owners do their own repair and yearly maintenanceIJ The Trend is here that NONE DO, every problem is a service truck or semi haul to the dealer. A high percentage of the Gleaner owners do all the yearly maintenance and a majority of the repairs themself. I own a Deere product and get the regular service package deals sent to me. Dealers begging for me to pay them on work that is fairly simple. Oil changes, filters, greasing, level checks. In my years with Gleaners, I have done 99% of all service and repairs on the machines, with NEVER having a service truck out or it hauled to the dealer, I have driven it 20 miles to the dealer for minor internal engine work.
