Has anyone done a DEF delete and DPF delete on a Mahindra. Tired of messing with this tractor and the regen mode. Thanks

I have the same issue. Mahindra and their dealers are not helpful. anyone knows of Reflash Service of the ECU that is reasonable
 
These regulations are intended for Vehicles drives on the road. I do not see the logic of such regulation imposed on the Ag industries considering the todays fuel is very low on sulfur.

Logic doesn't enter into this.

I have a friend with an M105P who found someone to do a delete. This guy had the tractor for like six months and charged about $3000 but he got it done and apparently the tractor runs a lot better now. As far as I know there have been no problems from the procedure.

I recall hearing something about a month or two ago about the EPA dropping DEF requirements.
I didn't read all the details but I don't see anything on their web site yet.

Regulations for Emissions from Heavy Equipment with Compression-Ignition (Diesel) Engines | US EPA

EPA regulations related to smog, soot, and other air pollution from heavy equipment.

Until/unless it happens, I think it's illegal to tamper with the system.

What Trump said is he was going to roll back the EPA standards back to 2020, before he left office. I don't believe there was any mention of eliminating DEF on diesels. Tier 4 final was passed back in 2004 and was final phased in by 2014. DEF was required on larger diesels starting in late 2010?
