2305 Power Loss

[JDforMe]

Greetings all... A question you.
I'm here in CT - Wicked cold, lots of snow lately ( for us at least ) so I'm moving lots of it...

Here goes...
2305 with FEL... Lately I've fired her up, starts no problem. A couple of minutes of warm up and off we go. Within a few minutes, RPMs drop, almost to a stall- especially when under load. (actually did stall once or twice). I back off using the loader for a few seconds, power back then give it the beans... RPMs swing right back to where they should be.... May happen a few times early on in the job, then seems to work itself out (USUALLY but not always) I can't figure out what I've got going on..

Starved for fuel? Clogged filter? Checked that, all looked squeaky clean...
Injector problem?
Fuel starting to gel? I DID treat the diesel with additive before winter, so probably not likely..
Something electrical? -hopefully not, out of my league to troubleshoot.

Just a few years old... About 150 hrs. All scheduled maintenance followed.
All fluid levels good...

I know it could be just about anything.... Just wondering anyone else had a similar experience. The fact that it happens under load is what has me confused.

Thanks

You did check the air filter?

Drain the fuel into 5 gal can and put in fresh.

I'm guessing your issues would disappear. Do the simple things first.

I wouldn't discount the fuel gelling even if you treated the fuel as this has been a brutal cold winter. I treated my diesel fuel also like always but had some difficulty starting and running a couple of times so I doubled up on the fuel additive and haven't had any trouble since. Very simple and easy to add more fuel additive and it may resolve your issue.

Mine did the exact same thing summer 2010. Did all you did plus more. Also noticed that at full speed you could see fuel level slowly drop in fuel filter bowl. I would idle down and you could see fuel filling fuel filter bowl refill with fuel. I physically removed rubber fuel line, the line that runs from tank to fuel filter assembly. A skinny piece of round black rubber came out of the hose. Know what it was? It was part of a rubber O-ring that was supposed to be on my diesel fuel tank cap. The O-ring broke apart, and somehow a piece about 1" long found and vibrated its way to my fuel hose. It effectively cut my fuel path in 1/2. Enough Fuel could get by at idle, but at full speed enough fuel could not get by. Took it out and runs like new. True story!

Really sounds like fuel starvation. Both Camillit and Sunnyside have good argument. Adding extra additive to the fuel would be my first try, but I always thought that because the fuel tank and filter is mostly inside the engine compartment on the 2305, the heat generated by the engine would have prevented the fuel from gelling. But then again, if you are using summer fuel and your 2305 sleeps outside, extra additive could do the trick.:thumbsup:

Another vote for a clogged fuel line. I had a similar problem with my 2305. I disconnected the fuel line and found a small blade of grass. That was enough to continuously stall the tractor a few minutes after starting. Cleaned the line and the problem went away.

that sounds a lot like my 2320 problem. I'm thinking that you have a glass filter bowl. Check the gelling thread for pictures of gelling and paraffin precipitation and then you'll know what it looks like.
Last week I asked the manager of my local Sunoco what type of diesel were they selling; type 1, 2, 4 or 6? The answer after a few days was type 2. bzzzt WRONG - next contestant please. Type 2 is summer blend with a higher paraffin content. Type 1 is what you want these days. I'll go to a truck stop next time for diesel.
I don't have gelling or paraffin precipitation but after ten minutes of plowing I get engine slowing and stopping. I think that it's water condensation freezing as I let the tractor sit for a minute and then restart it and get another hundred feet out of it before it stalls. I think that the heat of the engine thaws out the frozen water that's clogging the fuel line or filter. The partial solution is to always keep your fuel tank topped off.
Be aware that rising temperatures will ungell the diesel but not the paraffin problem (even 55 degrees temperatures). The solution for these problems is to run power service red can through it. You must have fuel flow though. You can get this additive from Amazon fairly quickly.

Thanks for the suggestions guys..... I'll take a look tomorrow morning and see what I can find.
Always great ideas and responses on this forum! I'll report back with what I find.

Best

I had the same almost the same problem a few weeks ago. I noticed the sediment bowl was a bit cloudy around the filter. When I removed it I found it was frozen water about halfway up. There is a little red ring that lays in the bottom of the bowl. My guess is water makes it float up so you can see how much water is trapped there. Anyhow the filter is dirt cheap and a very easy switch out.
