You don't think you got one that has been in a flood do you? Hydro fluid shouldn't look like that at all with that few of hours.

That may be the answer.

No, I don't think it has been in a flood. No other signs of any water damage. No rust, no mud in hidden crevices, no water marks on anything.
I also wonder about the algae. I always thought algae needed sunlight to grow although I am taking all comments into consideration. What kind of algaecide do you put in the hydraulic fluid that would be compatible?.

did you check and make shure the brakes are fully releasing with low hours - low service they do tend to hang up with low hours and service crawl under with a hammer and good rust penetrating oil spray and tap work them back and forth and see if it makes a difference

He can put the transmission in neutral on a slight incline and make sure it rolls rolls freely to rule out brakes sticking.
Since the rpms are dropping I think the OP should be able to safely focus on fuel related problems like algae. Might take a more comprehensive fuel system flushing.

I would drop the fuel tank and do a thorough cleaning. I had a major problem this last winter with water in the fuel and finally gave up and dumped about 30 gallons. Put about half a gallon of acetone in the tank and let it sit for about 15 minutes to absorb the water and then pressurized the tank to finish cleaning it out. Also found an in line filter that I didn't know about and it was completely clogged.

Thanks All for your reply's. I am really starting to think it is an injector problem. When we drained the fuel it was old but all of the water had collected in the separator. Have a Deere certified mechanic coming over to check injector pump pressure hopefully tonight or tomorrow. I will keep you all posted and thanks again.

You are correct, algae does need sunlight to grow... unfortunately many in the tractor/diesel community refer to a diesel biological growth as "algae". It's inaccurate, but there you go.

A biological growth in the diesel tank (plus fuel system/fuel bowl) feeds on a layer of water, which is on the bottom of the fuel tank as water is heavier. If you were to put an inspection camera down into the fuel tank (which I recommend that you do), a biological growth will look like fairy-floss (cotton candy) mixed with phlegm. You will need to dose the tank with a diesel biocide, which is readily available at any auto-parts shop/store.

Then you'll need to drain the entire tank and wipe out the dead biological growth using a 'grabber' (auto shop again) and many CHUX (J-Cloths). The dead biological growth will be stringy and brown.

I'd also wipe out the entire fuel bowl assembly. Only then would I add fresh diesel to the tank (+ this "seafoam" additive) and fire up the engine.

I have no idea what has contaminated your hydraulic filter.
