1025 kept slowing down

[RalphVa]

When running the bush hog for a short time this afternoon, the 1025 keep losing speed. I kept shoving the throttle farther and farther forward (it seemed). Did not want to stay near the PTO speed. It's not like it wasn't getting fuel, e.g. cutting out. It just would not hold the speed. The grass was not that thick or high.

Wonder if I should change out that dinky fuel filter off the tank?

Guess I'll also check the throttle assembly. Didn't seem like the throttle wasn't holding though, just lost speed and needed the throttle bar to go farther forward.

Anyone else had this problem, with the solution?

Was the throttle lever moving back on its own? Most diesel tractors have some sort of spring/friction assembly around the throttle lever to hold it put, otherwise vibrations from the diesel would let it move by itself. If you're not sure, check that first to make sure it's not looser than normal.

Figured it might be it. Will take the side panel off to see if it gives access to the throttle action. Doesn't make sense that it would be the fuel filter. Didn't act that way.

The throttle lever has a nut on the back side of where it's attached under the dash. You apparently need a special crooked wrench to get in there on it to slightly tighten it up. I may call JD again (called them once already because I had a leak; turned out the factory hadn't tightened the hose clamps enough). It's still under the warranty.

Never had this problem on the 4010, and I was always moving the throttle on it because it idled down to 1,000 rpm. Often needed more throttle when cold to start it and needed usually at least 1,500 rpm to run it.

Guy came out from JD and fixed it on warranty. The throttle has double nuts on the back side. He got to it from the other side, using a long extension and universal joint with a 17 mm socket. Just gave it a good tug, and it tightened up.

Got a bill from them for $249.38 for tightening the throttle. Will call tomorrow. Don't see it's any different from the factory not tightening the heater hoses properly (that JD paid for). Never had to tighten the throttle on the 4010 over 9 years and 660 hours, and it had to be moved all the time, as it idled at 1,000 rpm and needed to be 1,500 to do anything.

Your tractor is not under warranty? I could see them charging for a service call.

There's a 2 year warranty. 1st year isn't until July. They said it was a mistake.

That is good they got it straightened out:thumbsup:

Well, the throttle became loose again, totally this time. Only way I can operate it is with a bungee cord to counteract the return throttle spring. Must be a friction washer or something broke on the throttle lever shaft.

They billed me again for the service even after Scott said he'd take care of it. Wrote them a letter telling them that Scott promised that it was a warranty item.

It really is. There's something busted.
