I have a 2019 7060 that after 1 hour of use acts as if the tractor is in re-generation mode. During this time the re-generation indicator is not showing in my display. At times I do get the message indicator that the tractor is in re-generation mode cleaning out the dpf muffler and once done the tractor continues and sounds normal. However, after 1 hour of continuous use it acts as if it is re-gen mode constantly but no signal. Tractor will stay in this mode continuously as long as I run the tractor. During this time I must have it in low 3 gear or it will act as if it is going to stall. If I raise the loader or turn at the end of the field I lose 200 to 300 rpm. When I park the tractor and start up the next time it runs and sounds normal then if I run for 1 hour or more the problem comes up again. I have drained the bowl with minimal to no water and have changed fuel filter. Even drained all fuel and it was clean and still acts up. It started doing this at 100 hours and tractor now has 177 hours. I bought the tractor new. Any ideas?
