Thanks Bruce....so start the engine and press the auto regen switch every time even when at 50%? Or only push the auto switch when I know I am getting close. I have read some instructions which say on the older tractors you have to always push/activate auto by manually pushing button...
Depends on the model you have. Try reading this, the pdf in the first post has got pictures of the buttons to help distinguish. If you have the older kind like mine you have to put it in auto regen every time, or at least when it is close.
May well depend upon year of manufacture.
That's what my manual says to do as well...every time. I thought about waiting til my graph shows that I am getting close to an auto regen then start turning it on . Probably just get into the habit of hitting the switch to enable it every time...
I think (but can't prove) that your dealer might not be right about carbon building up faster if you haven't pushed the auto regen button. Passive regeneration, where carbon is burned off in the course of working the tractor, takes place fine in the inhibit regen mode. This can be seen in the display when the percent full bar graph decreases when the tractor is being worked hard.
That is what he told me back when I purchased it. I always automatically push the button and watch the graph on the screen and as you say it burns off when working hard.
The only thing the computer can't do is assess whether the tractor is in a safe environment for regeneration to occur. Exhaust system gets hot, and for example hay chaff in a barn could be ignited. Hence the utility of the inhibit regen button.
That is the way the 2014 and up L tractors are. The first year tractors like mine are the reverse. The inhibit mode is reset after key off, and you have to permit auto if you think the conditions are safe. Keep in mind in the L series tractors, only the 60s have the bar graph that tells the operator a regen will be needed soon. The folks with 01 tractors are flying blind, and have to pay attention to their dash for the blinking light to indicate a regen is needed, and to up the rpm if needed. I suspect that is one reason dealers tell operators to run these tractors at high rpm all the time, too many people don't see the lights and don't know what the beeps mean and get into trouble. If it in auto regen mode it will take care of itself.
