i have a L3901DT and had my 5th regen yesterday at 60hrs,the only problem is that i have to bump the rpms up to 2800 before the rpm indicator stops flashing and regen takes place...i have read where most people only raise the rpms to about 2100 or 2200 and keep on working..am i doing something wrong..i use my tractor mainly for skidding firewood and snowblowing and keep the rpms at 1900 most of the time.
It depends on what you are doing when the ECM calls for a regen how high you have to get the RPMs. I have been grading the private road and not have to raise the RPMs at all. But if I'm in the woods cutting firewood and taking logs to the shed to be bucked up and split I will have to raise them really high. It has to get the DPF hot enough to burn the extra diesel that it is injecting to burn.
thats what i thought but wan't sure..thanks for the info...probably wouldn,t havehad to raise the rpms that much if i was brush hogging...was in the woods when it happend
