I have a new MX6000 about 6 months old. 30 hours on it. I was working it for a short time and the warning light and buzzer came on for the DPF. So I followed the instructions and put it in clean out mode or whatever you call it. Got outside the cab for about 5 minutes, once I got back in the temp light was on so I immediately shut it down. Let it sit for about ten minutes and started it back up. No lights and everything seemed to be fine. Went to drive it home on the street, put it in high gear and it didn’t have enough power to get it going in high gear. It runs perfect but doesn’t seem to have enough power in high gear. It feels like I have a flat tire but I do not. Almost like a brake is dragging. I put it in neutral while moving and it stops right away. Me and my so tried to push it by hand in neutral and couldn’t budge it. Not sure if that is normal or not. I checked all of the brake linkage and I noticed a bad scratch on the bottom of the linkage underneath near the drivers rear tire right before it goes vertical to the rear end. Could I have hit a rock and bent the brake linkage or something like that or could it be something with the DPF Or the temp light Is there a way to manually clean the DPF or is the not an issue? Closest dealer is 3 hours away so it would be nice if I could figure it out myself. Thank you.
