2011–2014 John Deere 9R & 9RT DPF & EGR Delete Tune

The first 9R tractors met Interim Tier 4 without DEF, which put the whole emissions load on cooled EGR and the particulate filter. On a 9510R pulling a wide disc or air drill, those two systems are behind most derates and shop visits. Tune it on the farm with our Reflash Master handheld, or mail us the ECM for a bench flash. Both routes turn EGR and DPF off and can add Stage 1 or Stage 2 power. We ship all across the US and Canada.

After the tune

EXHAUSTHollow out or straight pipe the DPFWith regens disabled the filter will plug over time, so gut the canister or swap in a straight pipe. There is no SCR on these early 9R tractors, so the rest of the exhaust stays as built.
EGRBlock-off plate includedOur file keeps the EGR valve closed. The plate in the kit seals the passage too, so a valve that seizes open can’t feed exhaust into the intake.

Why delete the DPF and EGR on a 2011–2014 John Deere 9R?

DPF

Diesel particulate filter

A 9R spends plenty of hours off full load: transporting between fields, idling at the end of a pass or running a grain cart. Those hours are when the DPF loads up fastest, and an active regen burns fuel and holds back power while it runs. After ten-plus years, many of these large filters are also full of ash. Gutting or piping the canister puts an end to regens and opens up exhaust flow on the big engine.

EGR

Exhaust gas recirculation

With no DEF to help, the Interim Tier 4 9R controls NOx almost entirely by sending cooled exhaust back into the intake. That heavy EGR rate leaves soot in the intake manifold, stresses the cooler with heat cycles and wears out valves. A cooler that cracks can leak coolant into the engine. Turning EGR off in the file and plating the port removes that whole circuit.

Frequently asked questions

Q1Handheld or bench flash: which should I choose?+

The handheld suits most owners, since you tune the 9R in your own shop. Pick bench flashing if a high-soot derate can’t be reset on site. If the handheld can’t complete the write because the CAN bus is overloaded, the ECM will need to come to us for a bench flash.

Q2How quickly can the tractor be back to work?+

With the handheld, about 2 hours after we receive your stock read. A mailed-in ECM goes back out the next business day, so total downtime is mostly shipping time.

Q3Does the DPF have to come off?+

The filter needs to be gutted or replaced with a straight pipe after the tune. Since Interim Tier 4 9R tractors have no SCR or DEF, that is the only exhaust change.

Q4Which horsepower stage is right for me?+

Stage 1 adds roughly 10% with a focus on fuel savings and torque. Stage 2 adds roughly 20% for tractors pulling at their limit, and still helps fuel use under heavy load.

Q5Will a dealer update remove the tune?+

It can. Dealer reprogramming or a software update may write over our file, so read our OTA statement before the tractor goes on dealer service tools.

Q6How fast does the handheld ship?+

Most handheld kits ship the next business day to anywhere in the US or Canada. Expedited orders placed after 12 PM ET ship the following day.

Q7Disclaimer+
