4035 stalled while idling

[RedFirstGen]

Was doing some stone work today with my tractor. At one point I was racking out the stones by hand while the tractor just sat and idled. It was probably idling for 10 minutes and all of a sudden it just started sounding like it was losing power and few seconds later it quit. I hopped back on it and it fired right back up and seemed to run fine otherwise. Anyone have any insight as to why it might have stalled out? I didn't let it idle that long again so not sure if it would have done it again or not.

fuel shut-off solenoid... there are a few out there that had problems with them...mine included...mine would just shut off, didnt think that much about till it happened a few more times, then the last time it did it - it wouldn't restart at all... connector was full of water and so was the soleniod...dealer replaced it and not a bit of problems since

Never had a fuel shutoff issue on my 4035 (nor have I seen anyone else have that issue on their 4035). If it had been running for right about 20 minutes total, it was likely the KSB timer shutting off the cold start assist. For a cold start assist, the Bosch injection system runs at an advanced timing for the first 20 minutes of each startup, and then shuts down commonly causing the engine to run rough for a moment or sometimes stall when at an idle. I just keep mine at about 1500RPM if I'm leaving it set for a couple minutes if the cold start hasn't yet kicked off. After the first twenty minutes and the cold start assist kicks off, then I idle it as needed. Just keep in mind that the cold start assist kicks on every time you start the tractor, no matter how warm it is.

Thanks guys. I would say 20 mins is about right. I had done 2 or 3 buckets worth when it happened. It was idled all the way back (or forward depending on how you look at it). (1000rpm). When I let it idle after that I set it at 1500 rpm each time before I hopped off. I didn't really have a great reason just felt like the thing to do. . I'm hoping thats it but time will tell for sure obviously. Thanks again. This forum rocks.

If you continue to have an issue with it wanting to stall at 20 minutes, it is also amplified by the bad batch of fuel lines they had. Check and make sure your fuel lines are the newer style high pressure type hoses rather than the older style that had the braided covering on them.

Below is an example. The style of hose on the left with the braided covering is bad. If your lines are plain jane autostore fuel hoses or are like the ones on the right, you're good to go.

 

[RedFirstGen]

They are the braided type.

 

[Sysop]

Contact the closest dealer. They are a known issue and replacements are warranty. I think they may even replace those out of warranty being a known issue.

Thanks!!

Sysop,

You totally got this figured out. Fuel lines, check. KSB, check. Fuel solenoid (thanks J Wilson), check. In that order. I'd for sure, right now replace all of those black braided lines. It is way more of an issue than diesel leaks, they will let air enter into the fuel system, causing no starts and hard starts. When we replace them folks say, "wow, it starts so fast".

Great advice.

Just living the dream and trying to share.


Great bunch of folk here for the most part, much better than other corners of the interwebs. I enjoy reading and learning from all of you and from life, then I just parrot it back to the next new guy it'll maybe benefit.

 

[RedFirstGen]

Like I said. This forum rocks. Ive been here less than a month and am so grateful for all the amazing knowledge you guys have to share.

Quick follow up question. Any of you have an idea on approx shop hours involved to replace the fuel lines?

 

[Sysop]

Myself, only owning one, I couldn't give you an idea of the averages or anything. I think Dave would be able to provide a better answer being a dealer. All I can say is from my own, the work itself on just the lines shouldn't be much. An hour for the feed line and 15 or 20 minutes for the return perhaps...

 

[DavesTractor]

The only hard hoses to replace are the ones going to the tank. You need to remove the left rear wheel and drop the tank down just a little to get to those connections. Takes about 2 hours to do all of the lines. Easy enough work, except wrestling that big tire/wheel. Replacing the hoses is a must. Sometimes they last a couple of years, some times a couple of months. The new hoses are great and we have never seen a failure once replaced. One error many folks make is to just replace the easiest to reach hoses. Do them all.

While you are working on your tractor, make certain the power-steering hydraulic hose is positioned away from the starter positive terminal. Zip-tie it or do whatever to get some clearance there.

 

[DavesTractor]

The TSB for the hoses allows the dealer 0.92 hours to do the repair. Real time, about double that. That's why dealers are not so anxious to fill the shop with warranty work.

 

[RedFirstGen]

Thanks so much. I talked to the dealer before I posted my question. He said it would not be covered under warranty. When I asked him if he knew the approx shop time to do the work he said probably 5hrs ish. I thought that sounded like a lot which is why I posted the question here. I'm not saying he was dishonest- it sounded like he was guessing somewhat on the time. He also said If I'm not having issues with it why not just leave as is and keep an eye on things. The tractor is 5 years old with what I'm guessing are the original lines.

 

[RedFirstGen]

Another issue- maybe related. So, after sitting for 3 days I went out to the barn, turned the key and the tractor fired up no problem. Ran it for about 45 minutes straight then shut it off to do some shoveling by hand. Hopped back on it 10 minutes later and it won't start now. Cranks over but doesn't start. Getting frustrated. Could all this be fuel line related or likely something else?

 

[Sysop]

Yep. Fuel lines. Random hard or slow starts disappear.

 

[RedFirstGen]

Thanks. That's good news I guss. Will definitely get them replaced this week.

Around here we have a saying, "fix what you know is wrong first", then look for the less likely culprits if all is not fixed. You might have an electrical issue with the start solenoid, but I'd get the fuel lines changed out anyway first.
