All the DPF filters have a catalytic converter built in (well, Kubota and John Deere do). What Mahindra did to get there NOx and PM numbers within spec was to run a MUCH HOTTER temperature in the combustion chamber. The pistons, rings, cylinders and valves will likely have a reduced life span due to that.

That's what the propaganda masters at the other tractor companies tell me at any rate. Obviously a Regen exhaust system is more complicated and more expensive than the way Mahindra does it. If it was just as good, everyone else would follow their lead. Mahindra is to be lauded for the 7 year warranty they offer but you need to realize that Kubota and John Deere both have a 5 year Emissions warranty, which covers the DPF filter, fuel injectors, turbocharger and many other parts. They both also have a 6 year total powertrain (engine, transmission, rear end) warranty standard.

What Mahindra likely counts on is that the average buyer puts 100 hours a year on a tractor. Therefore the components should last well beyond that.

Manidra doesn’t have a DEF or DPF or any F for that matter. They developed their own system to get compliant. It is basically a catalytic converter that super heats the exhaust do meet emissions standards. There is no filter to change and no fluid. No regeneration cycle.
