SC Mn | Wondering if anyone else has issues with 6430 being the worst starting tractor ever???? It cranks incredibly slow no matter what the season. Took it back to dealer multiple times to no avail. Has a new battery and they claim everything checks out fine with starter. Cables have been checked as well.
The old 4030 series always were known for bad starting but I think this one beats it hands down! Doesn't seem right?
TIA

| Had a 6420 that I replaced starter and then harnesses...same as you stated...a real slow cranker.
Traded 20 for a6430 premium this past fall. I think the 30 is even worse than my 6420.
That frustrates my greatly. |

East-Central Ontario | The Mannheim 6000 tractors have all been bad starters for us. 6400 had to be plugged in to start anywhere below about 40 F, 6420 is just as bad. Anywhere much below about 20 F it has to be plugged in overnight and chances are it’ll still need ether, right from the time it showed up new |
|
| |
|
SC Mn | Why should a little 4 cylinder crank so slowly?? There must be something that can be done? Hate to waste money on a new starter only to find it's exactly the same outcome. |
|
| |
|
SC Mn | It's tethered to a plug in from november until may! Haven't resorted to ether yet but I'm thinking that's the next step. Won't start at all today with temps -15. Totally screwed here when I need it!
Did you add an either kit to yours or just give it a shot in the intake? |
|
| |
|
East-Central Ontario | Just in the intake |

eastern ontario canada. | well I must have the only one that starts. best starting tractor I have ever owned. 50yrs of starting tractors in canadas winter. |
|
| |
|
Ontario | The 6420 I've got seems to start fine. Plug in for couple hours and fires right up. Same with 6105m. Used it yesterday without issues and it was mighty cold out. Both tractors are in a unheated shed. The 6210 I have is harder to get going at temp below -20 celcius even if plugged in. |

Amherst WI | If you really think that is the worst starting tractor ever you've never owned an IH 560 Diesel. |
|

Extreme SW Minnesota Iowa border | Neighbor had troubles with his pump not de-stroking. Might want to look into that. Some how or the other his loader controls wouldn't let the hydraulic pump de-stroke. Thats all I remember.
|
|
| |
|
west central Iowa | I've started my 560 diesel as low as 18 degrees without being plugged in. If I plug it in it starts like it was summer. |
|
| |
|
| I don't know about that. We had a 656, and if the batteries were good, and the glow plugs working, we never had any problems. It would start much colder than the 8640 we have. |

just a tish NE of central ND |
How about a gear reduction starter, will that help?
My 6400 doesnt crank that slow, and you have less cylinders to hear each revolution than you do on a 6 or an 8 cylinder so it sounds slow turning over.
DIESELS.......... Cold starting issues have been an issue with diesel as long as I can remember in tractors but they keep getting better all the time!(for the most aport)
I figure if I wanted a real cold weather starter Id get out my dads M international that I converted to 12 volts and put #10 oil in it and it will start outside at -30f most times as long as the distributer is dry and the battery is good. But, brrrr.....I sure froze myself a lot on that thing in my lifetime though....(:
.
If its built like my 6400 I sure dont want to be the one changeing the starter in the cold wind and snow...... its about the f%^&*ugliest place to get to the bottom starter bolt even though you can stand there comfortably and work on it....... just no room in there..dumb dumb dumb location for it under the rail

| I don't think you can say hard starting diesels have always been a problem. Our old IH 1566 would start just about anytime and any temp. From my experience, JD has always been the one with hard starting diesels. |
|
| |
|
ohio | I've got a 6410 I bought new.It has never started right when cold.I just got home from my heated shop and charging the battery for two hours in case i need to push snow.I've done the battery,cables,etc also.Starts great when it's warmed up. |
|
| |
|
SC Mn | Just no cranking power so it seems, not enough to even get a whiff of ether. |
|
| |
|
west central Iowa | We were just fighting a starting issue with our telehandler with a JD engine. Turned out to be an issue with the Stanadyne injector pump. It caused engine to turn slow and not start.
Something to check anyway. |
|
| |
|
SE Wisconsin | Guess I’m lucky with my 6400 at least. Had to do the starter once. Yup PITA. But the original batttery lasted like 8 years so I keep a JD one in it and it really cranks. Also, are you guys using the glow plug? I don’t like to do it but if I have to it’ll start down to 20F with just that if I didn’t plug it in for some reason. Fired over the weekend at -4 after being plugged in for about an hour and a half. Would have liked to have it plugged in longer though. Maybe just lucky like I said. |

SC Mn | I've had more choice words than that this am!!!! |
|
| |
|
SC Mn | That's interesting, never thought of looking in that direction. |

Central Nebraska | Get a gear reduction starter for a power unit and move solenoid to a different mount like I had my John Deere dealer do and it’s made my 6400 easy to start! |
|
| |
|
Camp Douglas Wi. 40miles nw of wi. dells | If you really want a hard starting Diesel, gotta get Case 830 Diesel, was a great running tractor. In summertime cutting hay, if below 70F had to give it a whiff of either.

Fort Recovery. Ohio | We do not get the cold weather you guys in the north get , but this last week it has been -10 or better and our 6420 has no trouble starting after its been plugged in for 30m or so! |
|
| |
|
| When I first read your subject line, I thought no way!
That award has to go to a 40 or 4230 John Deere...
But I see you got that covered. It must be bad. |
|

|
SC Mn | How long does the glow plug light stay on for you 6400 tractor owners? Mine stays on only for an instant then goes off? I'm thinking it should be on longer than that? |
|
| |
|
Southern Pa. | I've owned a late 6400, a 6410, and presently have two 6X30 tractors. The 6410 was the laziest on cranking speed, but it was never a big issue. If it gets to 20°F, I'll plug them in for an hour. Add 1/2 an hour of plug in time for every 5°F lower than 20°F, and they start like summer. Love every 4.5L I have. They have been very good to me.
To the OP, something is seriously wrong. |

They don't have glow plugs, they have an intake heater. Turn the key to the run position, and push the switch in. It will heat until you let off. But if your cranking speed is bad, you need to fix that first.
Whatever you do, don't use the intake heater AND ETHER!!! |

I’ve always disliked those 4.5 engines. Not only are they a hard starter, they also have the $450 battery that gets so damn worn out trying to start that stupid engine. Gutless, hard starting POS.
I have an '08 6X30 tractor we bought new. Original battery is no problem in the 0°F weather we have been experiencing. The battery will be 10 yrs.old in May of '18. It's not at all hard to start. |

saskatchewan and Washington | What oil weight are you using? |

S.E. MN | Sounds like my '72 4320 ,has a block heater that above 10 works fine. Added a tank heater (heater hose) a number of years ago, now if it's really cold plug both in and does that ever make a difference ! |
|
| |
|
Ontario | 6000 and 6010 series had intake heaters that would come on when pushing key in. I believe 6020 and newer have glow plugs that only come on at a certain temp. Would be nice if they could be manually activated. |
|
| |
|
Ontario | The 6210 will catch but it chugs and belches smoke. The injector pump appears to be over fueling. After a bit it clears up and runs fine. |

My 6430P hasn't even turned on the intake heater the last 2 mornings. It's been plugged in for 2-3 hours and the water temp shows 70-75 degrees when I turn the key on. I'm surprised mine hasn't ran the intake heater because in the past I've seen it on for 5-15 seconds. It's been -15 here the last two days and it started fine. I put a new battery in it a month ago. I tried ether in mine before and won't ever do that again. It got to the ether and STOPPED turning over momentarily. It didn't like it one bit and still wouldn't start.
It does seem to require a lot of amperage to start such a small engine. If I were you, I'd check the water temp to confirm the block heater is working. Then I'd check battery cable connections and possibly replace cables with new/bigger ones. It doesn't take much corrosion to cause resistance. Then I'd replace the battery. Mine tested good when I replaced it, but wouldn't turn the engine over fast enough when it got cold. Mine has started perfectly since then.
Disclaimer: I'm no mechanic.
Good luck

ohio | Even with a new battery mine won't turn over fast enough to start. The glow plugs run the battery down faster and all it will do is grunt. If I plug it in for an hour then put a high charge battery charger on it then it will start. |

SE Wisconsin | Mine stays on as long as I hold it. Usually count to 30 and hit it. Boom it’s running. That’s down to 30 degrees or so. Colder and it’s plugged in. Last Deere battery I got at Deere was about 350 I think. Don’t like it but it starts. That’s more important to me than dorkin around when it’s cold. My 6400 is a ‘96 with 4100 hrs. |

ecmn | dad had a 6420 in the other week. the guy said if it gets close to 30 degrees he has to plug it in. ? how in the heck since 2005 is there a tractor that doesn't start at 0 degrees? |
|

Osakis, MN | Each one of these posts surprise me about hard starting. I just replied to a different thread about how a 6200 we have will start awesome in cold weather. Last year it sat on the auger outside for a week of subzero temps. Was sitting on a farm 6 miles away and when I started it I pushed the key in for a 10 or 15 second heating and it started within seconds of cranking.
I put a new battery in it a couple years ago and the JD parts guy said that the battery I exchanged for a new one had to be the original battery. If not it was at least 8 yrs old that's how long we had it. Starts like a champ.
9370 with a 855 Cummins big cam mechanical pump. That one needs plugged in below 40 degrees. When it does start it coughs and hacks and looks like the forest is on fire for a while.

Northwest Mo | High hour 6110 needs pluged in below 35 degrees. Have a high hour 6430 Prem and a low hour 6430 regular, best starting tractors I have ever had either pluged in or not. Fast cranking start quick as long as fuel gelling is not a problem.
-18 and -30 wind chill recently. Need very good battery and good cranking speed first. Both 6430's used EVERY day. |
|
| |
|
Northwest Mo | Go to some other farmers who have 6430's and have them start them, to see if yours really is starting that slowly. Has to be a problem. I would consider another mechanic. May have to recheck all electrical connections, battery, cables, and starter. For me 6430's are the best starters..... |

Agreed. We have two 6X30 series tractors. Both bought new, and they are among the best cold starting diesels I have ever owned. Our NH skidloader may be a touch easier, but those three pieces are the best cold starters here, hands down.
If you have a hard cold starting 6X30 series, something is wrong. |

SC Mn | Follow up.........Block heater is good, water temp registered 109 yesterday when trying to start. The 6430 has glow plugs. The glow plug light comes on with key but shuts off quickly, definitely something not right with them.
Put new battery in yesterday after running knipco on engine for an hour, still no luck. Finally the starter decided to take a complete dump, mechanic who was working on it said it definitely should crank faster than it did before dumping.
New starter shows this morning and I'm crossing my fingers it cures all my issues with this thing.
Hat's off to mechanic yesterday, it was so fricken cold in the wind while he worked on the starter with frozen fingers.

Northwest Mo | Your dumped starter may be the best thing to happen to you, but not the cheapest. Hope that fixes cranking speed!!!!!!!!
Like said earlier, all braided fuel lines need to be replaced with new american hose and clamps. Antifreeze smaller lines reclamped and o rings between resesivor and tank if you are getting antifreeze loss. |

Salem, Oregon | Take off and clean all grounds. That fixed mine. Under the right side operator platform is the one that fixed mine, another one on the side of the motor and the 3rd one by the bcu that is to the right side of the seat more towards the back. Take them off clean with a file, grinder, when putting it back on put a new flat washer on the back side. I would do think even if you the starter helps.
Any questions you can call me.

Check your tractor to verify what I'm saying. A 4.5L engine has a preheat feature, but not what I call a glow plug engine. A glow plug engine has a glow plug for each cyl, in the combustion chamber. What you have is an air intake 'preheater'. They are both aids for cold weather starting, but not very similiar otherwise. |

JD 6430 Premium- Worst Starting tractor ever?
