I have just finished harvest in Australia using a 2000 model 2388. the problem I have is that the air filter element needs to be blown out at least four times a day. The idea of the air intake being positioned at the rear of the combine is a joke. I have been working with a 2188 in exactly the same conditions and that machine needs blowing out after three days. so much for improvement. My machine is fitted with a straw chopper and I believe this dosen't help as it creates more dust. Has anyone got any ideas. After three days on a 2188 one blow, three days on a 2388 and I have done at least 12. I don't want to spend more time cleaning air cleaners than harvesting.
