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.

 

[RalphVa]

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:

 

[RalphVa]

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.

Mostly off your subject.
Sorry to hear you are having trouble with a new JD 1025.
My JD dealer is telling me my 1025R will break shear pins at startup on a 4' Brush Hog and I should buy a JD with a slip clutch. What is your experience?

 

[RalphVa]

Haven't broken a shear pin yet on my Frontier bush hog; only have spare bolts from the old JD bush hog, hoping they'll work on this one. The hydraulics on the 1025R apparently have something built in for a smooth startup. Not much chance in popping a shear pin on startup. On the 4010 that I had, yes. That thing would slam the PTO on. I often had to restart it 2 and 3 times to get the bush hog blades swinging properly. One time, I even had to stop it and get underneath with a pry bar to get the blades apart. They'd locked up on each other with the abrupt startup.

I fixed the throttle myself today. Just didn't want to go through waiting for the service man again, etc. I looked at it, and nothing appeared broken. There is a BIG washer behind the 2 lock nuts. I just got a 17 mm socket and put a universal on it and a very long extension to reach through from the back side (left side panel off). The nuts were very loose. If this happens in the future again, I'm gonna put a glob of Goop (heavy silicon) on the end of the nut and on the shaft to see if that will stop the nuts from working loose.

Maybe try a nyloc for the end nut?

Nick

 

[94BULLITT]

By lock nuts do you mean jam nuts? Maybe the service guy did not get them tight so they vibrated loose.

 

[RalphVa]

VERY difficult to get in there at the 2nd nut. You can mainly only get a wrench on the end nut and tighten up.

Would require a very special 17mm wrench to get it in there on the other nut, the one up against the washer.

Ralph

Nyloc nuts are self locking. They have a nylon bushing crimped on the end which keeps them from loosening off. You don't need to double nut a bolt with ny-loc nuts although if properly installed, I have never had a double nut loosen off.

A trick I have used in the past when a "Specialty Wrench" was needed, was purchase a moderately priced wrench at Northern Tools, and heat and bend the wrench into the configuration needed. You may also be able to reach into the area with a "Crows Foot Line Socket" or a "Starter Wrench". Here is a Google page of specialty wrenches. https://www.google.com/?gws_rd=ssl#q=speciality+offset+wrenches

I run a 4' Howse rotary cutter on my 1025r and have not had a problem with shear pins breaking. Engage the PTO at low RPMs (I usually engage at just over idle) then slowly rev up to PTO RPM. I haven't had any such problem at all...

I had a similar problem on my 1026R. I had to have the friction disc on my throttle lever replaced because it wore out.

 

[RalphVa]

Is the friction disc behind that big washer that's immediately behind the lock nuts?

So far, mine's holding now after I retightened it myself.
