2025R Mystery

[dodge man]

JD has a decent fuel filter setup, that’s fine on my opinion. I’ve burned a lot of biodiesel in mine with no problems. There is a funnel designed to catch water and containments called Mr. Funnel as I recall.

Also why don’t you humor me and replace the little filter again under the floor board. I’ll sleep better tonight.

OK, here’s an update, but the bottom line is… no improvement.
Added anti-algae additive
Changed both fuel filters again
Ran it backwards up the hill- no change so angle doesn’t seem to be an issue
JD and I both looked in the tank- nothing noted
I did note that if I fill the sprayer tank and don’t engage the sprayer (the PTO), the tractor does fine up the hill with the tank off the ground (3 point up). With the tank on the ground and when I engage the PTO it seems to overload… and that’s with the fan off. Turning on the fan will load even more.

Anyone had experience with a kink in the fuel line or something like that which would restrict fuel supply under load?

JD is still stumped as well.

Most of the fuel lines under the tractor are visible. I assume you took a look at the air filters? There is both an inner and outer air filter.

Another thought. Is your sprayer and/or pto pump functioning OK? One of those isn’t loading down the tractor harder than it used to is it?

IIRC you need to follow the fuel line from the little filter under the floorboard, it goes up to the first lift pump that then feeds it to the main filter by the injector pump ...

I don't have, and never had owned one of these or the similar 1025R, but I've read a lot over at the Green Tractor Talk forum about this ... That when changing that little filter, there isn't much room, and easy to kink the hose ... Even if it seems to "un-kink" the inside might not have, or it may have come unlaminated inside, and causing a blockage ...

If you disconnect the hose at the lift pump, does fuel gush out?

Looked at one air filter- in a canister right under the hood. I thought there was only one-lmk where the other one is. The sprayer functions correctly, but no way to tell if its creating more load than before for some unknown reason.

I haven’t disconnected the hose at the lift pump, but the JD guys did a fuel test - although not under load- and the system performed within specs. I asked them about the kink. I haven’t heard about the tubing de-laminating but can attest to the fact that it does have to get scrunched in order to get that in-line filter out and in.

Where are you located? The odds of you being close enough that I could try my 2025r out with your sprayer is very slim but you never know.

The air filter on mine are a white outer filter which turns gray for me when it gets dirty. The inner filter is blue and is much smaller. The inner one is a backup filter in case the outer one fails, I’ve never changed it on mine in 580 hours.

 

[Shawn T. W.]

Yeah, if you pull out the the air filter element, you will see another smaller diameter filter nested inside of it ...

 

[dodge man]

I haven’t seen it on a tractor but have on a couple of different cars where the air cleaner is packed full from a mouse nest. That’s why I bring up the air cleaner.

Has the sprayer got a lot of hours on it? When is the last time you pulled the pressure regulator apart and gave it a good cleaning? I’d also check the return/relief hose that goes from regulator to tank, they can get plugged up especially if you’re using a lot of dry fungicides like sulfur, captan, or fertilizers. Could be other hoses and fittings in the system also that are partially plugged up causing restrictions and increasing hp demand. Also check any inline filters to make sure there not plugged.

Minimal hours. The tractor only has 75 hours and maybe half of those are with the sprayer. JD wants the tractor and sprayer back and I think thats one thing they’re going to look into, although you need another 2025R or another a nifty fifty and a 20-25 degree slope to really check it out. I think it’s unlikely that it’s the sprayer given the low hours and I take pretty good care of it. LMK if you have any thoughts on straightforward things I can check on the sprayer and I’ll do it. Thx.

I’m in Carmel Valley, CA. Too far. I’ll check the inner one tomorrow.

Here is a link to a 1025R (very similar to what you have) https://www.greentractortalk.com/threads/air-in-the-fuel-system.199918

And another ... No fuel in the primary fuel filter both links end up to kinked fuel line.

ETA - I have a Fimco 65 gallon sprayer FIMCO 65 Gallon 3 Point Complete with 6 Roller Pump and 7 Nozzle Boom which does up to 150 psi, but only uses less than 2 PTO HP.

• Cast iron 6 roller pump provides up to 9.76 GPM at 540 RPM

Either there is something wrong inside the PTO itself, or the sprayer if the fuel line is not restricted ... You could try to replace the fuel line ...

I did note that if I fill the sprayer tank and don’t engage the sprayer (the PTO), the tractor does fine up the hill with the tank off the ground (3 point up). With the tank on the ground and when I engage the PTO it seems to overload…

What is the significance of it being on the ground?

So even if stopped on flat ground, just engaging the PTO will cause the engine to bog down? (Wether on the ground or lifted up off the ground with 3pt?)

Do you have another PTO attachment to try on it?

Yeah that’s pretty far.

 

[Runner]

I would do this. See if you can drive up the same hill with something else running on the back (stump grinder, mower, etc.).

Thanks. I’ll get under it and check it out. Those links were really informative.

If it’s on the ground, it’s also dealing with the drag of the wheels. The sprayer is a Rears Nifty Fifty-

I have a tiller. Might try to do after the rain….

Took a quick look and while there’s a 90degree bend in the tubing, it’s not kinked around the in-line filter. Hard to see the entire length because too much stuff in the way.

Inner one looks fine
