MX5800 DPF regen

[coolbrze]

I've read the manual twice & am still confused by the regeneration modes. Seems like there are several different options & I have no idea what to do when my MX does this... Can someone explain in english what I should do haha? Thanks!

The regen process is mostly automatic and there isn't much you need to do. I've gone through about 6 regen cycles so far on my MX5800. The regen light will start to blink when the cycle is about to start. Just keep working the tractor with the RPM above 2200. I've gone through several cycles while mowing and hardly noticed. You will see some black smoke in the exhaust and notice a slight fuel smell. The cycle lasts about 10 minutes depending on what the tractor is doing.

Occasionally, the dash lamp will flash asking you to increase the rpm if the tractor is at idle or working too slowly. A couple of times, the regen started just as I was putting the tractor in the barn. You can cancel a regen cycle if necessary but don't do this more than twice. In my case, I just let the tractor do a "parked regen" by setting the brake and letting the tractor run at around 2300 RPM until the cycle completes.

It isn't really a big deal. Hope this helps.

My 1st Regen was last week at 36 hours on the tractor.
It took about 2 1/2 hours.
I was using the backhoe when I started the Regen and was told not to exceed 2000 RPM for the 1st 50 hours.

I was running around 1500RPM

After watching the Regen flash for over 2 hours I kicked the RPM's up to the PTO speed and with in 15 minutes or so it was finished.

The next time I see the Regen light I will kick the RPM's up no matter what I am doing with the tractor.

The dealer tow truck driver told me that the MX series tractors need to be Parked to do the Regen.

When I did the walk threw during purchase they told me that I could work the tractor while it was going threw the Regen. It would do it automatically.

Next time I will help it by upping the RPM's myself.

I have had 4 regens on my 5800. No biggie. Kick the rpms up and keep going. If the light is flashing it wants to regenerate if constant light it is regenerating. Takes 15 or 20 min

The regeneration burns diesel soot off the particulate filter.

The engine needs to be running at about 2,200 rpm (2,000 rpm on HOT days) to generate sufficient heat to burn off the diesel soot.

Fuel cost is about $1.00 during stationary regeneration, which takes about sixteen minutes.

Thanks guys, sounds simple enough, appreciate the help!

Hi, Cool. Hope you are enjoying your MX. We have had only one regen on our MX in 48 hours--occurred after about 30 hours, as I recall--maybe because when we use the tractor we tend to keep the rpms up. Our regen lasted about 15 minutes, as I recall. Just be sure to get the rpms up to 2200 or slightly higher (whatever the manual says--I don't recall).

Lol. Your Regen didn't take 1.5 hours. It took less than 15 minutes.

It's always good practice to read your operators manual! If you won't read the manual at least read the sticker on the left fender (can read it from the seat even). It will tell you that the flashing lights means the tractor needs to do a regen but the RPMs are too low. The tractor didn't start the regen until you increased the RPMs.

There's lots of good information information in that manual (seriously) and it's a heck of a lot more trustworthy that the delivery guy. :drink:. It will even give you the correct break-in process.

The dealer informed me not to rev. the engine above 2000 RPM until after the 1st 50 hours for a proper break in.

I followed their advise until the Regen took so long.
They also informed me that the Regen would be automatic if I pushed the button when iit started flashing to allow the Regen instead of delaying it to a latter date.

I am at 45 hours now and the 50 hour break in is almost over. So after the break in I will be running the my MX5800 at a higher RPM to help the heat build up.

So you understand that most of what you just wrote is incorrect? Just making sure. You have a great tractor. :thumbsup:
