New 2620 won't start---ideas?

[trum979]

Have had a new 2620 for a couple of weeks now. Got down in the 30's last night when I went to start it this morning, it would fire up initially and just die. All my BX's started up so easily that I seldon had to use the glow plugs. Any how, I tried several combinations of preheat times and throtle setting and after about a dozen tries, it finally took hold and ran. Used tractor for a half hour or so and shut it off for about 15 minuites and tried to start it again. Same thing, engine would fire once and die.
Hoping it is something simple like a key switch or a stop solidnoid that I can fix myself. Otherwise, I will have to get it loaded on a trailer somehow, with the loader on and take it to the dealer where no doubt it will sit for 2 or 3 weeks. Anyone else had similar experience with the standard B series and found the answer? The tractor only has 5 hours on it, and have already had a couple of problems with it. I have 3 fairly new Kubota products and have had minor problems with all 3. Am beginning to question the quality of their products anymore, that I used to have such faith in.

I had the same exact issue! First weekend I used my B2620 sometimes it would not start. The same thing you describe. I tried everything. Make sure all of your controls are set as it states in the manual before starting. I never actually pinpointed what may have been causing the issue but mine seems to be fine now. I think someone may have mentioned that there could be a fuel venting issue but I didn't find any evidence of that.

I'm going out in the next couple of hours to fire it up so I'll see if I have the problem today. If you figure any

Sorry for the broken post...

If you figure anything out...please post back as will I.

Thanks for your reply. Was hoping to get some suggestions from some of the more informed tractor people on this form. ;that had experienced something similar on their Kubota. Guess that's not to be. However, here is where I stand, I talked to the head mechanic at the dealership Sat and let him listen to the initial firing and then shutdown of the engine over the phone. He sounds sure that it is in the wiring circuit that controls the stop solenoid. He says it could also be in a fuse, but I don' see how that could be. I also suspect the key switch.
However I learned yesterday that the problem seems to lessen when the outside air tempture is higher. It was in the 60's here yeaterday and it only failed to start a couple of times. Everytime I shut it off I leave the FEL bucket raised and resting on a prop in case I have to winch it up on a trailer.Have you had any more problems with yours along these lines? I WILL resolve the problem one way or another and will keep you informed of what I find. I'm kinda bummed out about having a new tactor with only 5 hours and having about 6 months wear on the starter and related components just trying to keep it running.

Could fuel gelling be a part of the problem?

A couple of years ago I had a problem with getting my BX24 to start and run well. It was early fall but the temperatures had fallen and I still had summer diesel in the tank.

Just a thought.

When it warms up does it run properly?

Some thoughts:

1) The engine on new machines are very tight until the break-in period is finished, and the cold makes it worse...
Once she starts bump the idle up a bit until she warms up.... This will go away...

2) Check the air filer and make sure you don't have a mouse nest.... I had that once.

3) Check to make sure ther eis no water in the fuel filter/bowl. I have some water in a fuel bowl and if froze to slush and blucked the fuel flow... New filter and all was fine.

Regards,
Chris

Here's my status from this weekend. I fired the 2620 up Sat morning around 8:30 am. I live in central PA where it was about 48 deg that day. Smoked and sputtered a bit but it fired right up. I used the tractor all day and it failed to fire on the first try one time, and I think it's because I wasn't totally on the seat when I fired it and all the other safety devices might not have been engaged. I'm assuming the 2620 has a safety dismount switch on the seat that kills the engine if you get off without brake being engaged?

Anyway.... I can't see that I have the problem anymore so sorry I can't give anymore information.

I don't think I had a fuel gelling problem since the first time mine acted up the temp was in the 70's.... No correlation to cold weather. I also run the same diesel in my F350 and have never had issues.

Keep us posted.

I have a 2920. I have never really experienced that issue. It sounds like a fuel issue if the engine turns over but it will not start. I will typically use the glow pugs for a few seconds if it is below 70 or so and any time it does not immediately start.

Mine will start even if I am not in the seat as long as the PTO is disengaged and the forward/reverse pedals are centered.

If the forward/reverse pedals are not centering, it will stall as soon as you get out of the seat, even if the PTO is not engaged. It will then not re-start until you center the pedals, but the engine does not turn over. There is a grease fitting where those pedals pitot that you should occasionally grease.

If the seat switch is bad, it will stall when you start to push on the pedals to move the tractor or if you try to engage the PTO. Mine started causing me trouble and when I figured out what it was I pushed it a bunch of times which probably cleaned the contacts so that I did not have any more issues with it, but I got it changed in warrentee.

sounds like water or something with fuel. my bx2660 starts with no problem and it starts with out me on seat and no break on. Mine is garage kept but not heated. Maybe corrosion on wirng safty switch. Good luck

It sounds like a fuel related problem. Make sure you have good clean fuel and give it some fuel conditioner. If you are using diesel with any biodiesel in it try and find some without. I have at least half a dozen engines that became crappy starters with biodiesel. It will likely get better with some use too.
