Southern Illinois | Considering trading an older 4WD for an 8430 and was looking for some real world comparisons. We have an 8420 currently and love it for power, functionality and creature comfort. My question is, how does and 8430 compare to it in those 3 aspects? I am only looking at PS and not IVT's. Nebraska Tractor Labs say the 8430 puts an additional 30 HP to drawbar and was wondering if that was seen in real life trials. Does anyone have any negative things to say about going from a 20 series to a 30 series? |

| 9 litre engine is a torque animal compared to an 8.1, don't like the engine fan and components, too complicated and too expensive , also dealing with the EGR and related components, otherwise very nice tractor |

Eastern Iowa | Ironbar - 3/8/2018 11:01 9 litre engine is a torque animal compared to an 8.1, don't like the engine fan and components, too complicated and too expensive , also dealing with the EGR and related components, otherwise very nice tractor and turbo actuator and variable geometry turbo, all nice stuff till it doesn't work. |

| Buy another 20. The 30s have the variable speed fan that gives lots of trouble. Also the 30s have more electrical crap on them. My cousin spent 40k working on 2 30s one year and never touched the transmission or engine. I also like the thumb operated three pont much better than the push button on the newer tractors.

Zabcikville, TX | We've got an 8520 and an 8530. Id go with the 30 because of the cab. We've had very few problems with the 8530. Fan was updated with a pip. No other problems. |

NW KS/ SC ID | Guy I help during harvest had a chipped 8320 long tip, and traded for a 8430. Both are ILS PS.
8320 had more snort, rarely lost a sensor. 8430 is gutless by comparison, and eats sensors often. Fan drive hasnt blown up yet, but it probably will. IMO stick with the 20 series.

Northern Illinois | I would agree on the 3 pt. I have a 20 and 30 series tractor. If you are going to use the 3 pt or more importantly if your father or father in law is going to use the 3 pt I would recommend the 20 series. |

| I have 30 series now but had 8420's and both are good tractors. The 30's will have factory auto steer, 50 inch tires, heavy duty quick hitch, heavier drawbar pin. I believe the front bracket/weights have more clearance than the 20 series. As mentioned the 30 series have had the fan updated by the owners pocketbook, and I have to clean the cab fan located under the floor seems like every other year which is kinda of a pain. I have one ILS and one 1500 front axle and both seem equal. The 1500 axle is rated for front mounted tanks. |

NEIA | I prefer a 30 series myself but both are good rigs. I always felt the 8.1 had more lugging power and the 9 L had more top end power. Both will pull good if you know when to shift. 5000-6000 hours seems to be the engine life on the 20s. The hood is replaceable with a newer style on the early 30s which is less prone to cracking. I'm not sure if Deere did much with the 20 series replacement hoods to reduce cracking. They are like concrete- cracked or going to crack. Common rail fuel injection on the 30s vs Bosch pump. Toss up?? More electronics on the 30s but honestly have never had problem. |

ND | The 8020 series had the last best JD engine, the Tier 2. Tier 3, and interim Tier 4 choked down the engine. And we are not even discussing DEF. Worse yet. I like the KISS method. simpler is better. |

Central iowa | I work on these for a living, hate the 30 series in aspect of more wires, sensors, fan drive, egr carp but the put a lot of food on the table.. Dad has a loaded 8420 with 4200hours just put in updated ils input shafts, accumulators have been fine on his( there is new/ better version out in r series), the asperator fan and logic plates is the stupid part on 20 series.. It will die on the farm! |
