It's practical and specific about the regen process but doesn't touch pricing, specs, or a broader tractor overview. Best for current or prospective M4 owners wondering how regen works day-to-day.
Posted by owner-operator Blake Perkins, sharing hands-on impressions from daily use on his own property.
The dash shows a PM percent display and a flashing light asking you to raise RPM, usually to about 2200, which starts burning the particulate out of the filter.
The owner says probably only two or three times a year, mostly in fall and winter, since summer work usually burns the soot out on its own.
Yes, the owner raises the RPM to trigger regen then continues dumping a trailer of sawdust while the regen finishes in the background.
No, the owner states this M4 does not have DEF or exhaust fluid, but it does have a particulate filter that requires regen.
