Hi to all out there.
I have an old Case 2144 and a 9660STS. Call me stupid but am getting another JD. Have to get new 9570 as the supply is short for 9670. My problem is this, my combine cathces fire the minute it gets a bit dry in chickpeas, sunflowers and even sorghum. I land up having to blow the engine compartment out every tank otherwise I have fire.I am talking 10 fires a day at least. JD dealers say it is too dry, however my competition with a 2388 case was going along quite happily for three days without blowing his machine once. Have asked the John deere guys what is the moisture cut off point for the machine they get full of excuses. I am not here to fight but to try and solve this issue . Bot machines are full of dust,both with thirty foot heads doing the same speed, so same amount of material. The only difference 9660 has big muffler, Case straight thru pipe. I can only deduct the back pressure from the muffler just makes the turbo hotter and this ignites whatever dust touches the turbo. I want to remove the muffler and put straight thru pipe, no noise issues here in Africa. What is the consequences to engine and performance, runaway turbos etc? Need some techinical info here, will turbo run cooler? Already have new airscoop, just reduces dust levels but does not stop fires. Radiator also cleaned everyday so engine is not running hot or straining.
I contract harvest and cut when the farmers want me to cut. We do not have driers and so have to wait for the wettest part of the field to be dry enough to cut and store. Therefore the driest part of the fields are already quite dry.
I look forward to hearing from similar sufferers and their experiences and any suggestions are very welcome.
