Hello All,

I'm new to the forum and came here for some help. My In-laws purchased a new 1025R in 2015 to do some simple chores around the house. It is manly used to muck stalls and move gravel. It's not overused or abused at all. It only has 106 hours on the dash.

A few weeks ago, I was using it to fill a waterline trench. The tractor was at an appropriate RPM, and all of a sudden, the rpm elevated to high rate and the machine began to smoke. I killed it, lowered the bucket and throttle. I restarted the machine, and it ran like normal. We thought it may be a fluke, or an issue from having it on un-level terrain??

Well yesterday the problem returned and was much worse. My father in-law was using the machine to move rocks from the pasture. He had half a bucket, and was transporting them by road to a washout. He said the engine rpms started to screamed, and he tried to turn it off. He pulled the key, and supposedly it continued to run and engulfed the area in thick white smoke. He got off the tractor and in theory, waited for the engine to blow. The machine died after less than an minute. I was not there to witness, but i saw the smoke, and there was A LOT. In my experience, this sounds line a run-away diesel?

He came and got me, and I inspected the machine...It was just topped off with fresh diesel, oil was full, and it cranked over. I thought for sure it would have been ceased or hurt. I turned the key, and it fired and ran normal??

Any idea from the experts, bad piston rings, stuck injector? I searched the site, but I didn't see any similar issues.
The local dealer is coming for it tomorrow, and they are totally stumped. They said they would need to see the issues repeated to diagnose.


Thanks in Advance, Jim

I was under the impression that diesel runaways were rare with non-tubocharged diesels. Any oil in the air filter cannister? Any possibility that somebody might have inadvertently topped off the tank with a little gasoline?

Aren’t 2-stroke diesels more prone to runaway?

No oil in filter housing. Tank has fresh diesel. I just purchased it. I know it was diesel because I just informed them to use off-road diesel. I see that the fuel filter is now red. They were using taxed fuel...we couldn’t have that.

I don’t necessarily know if it was a run-away. It shut down. All of the cases I saw where a true run-away occurred, there was carnage. ?‍♂

Just throwing ideas out there.
Something wrong with the fuel pump governor or fuel shut off solenoid sticking and not shutting off the fuel supply?

My money is on the air cleaner mounting position related engine damage. I strongly suggest the OP familiarize himself with the air cleaner issue on these machines............I think it's going to be "new engine" time when the dealer inspects this. I could be wrong.......It's been so long since the last time, I guess I am due......:hide:

This is one place he can start.

New Air filter update. FREE.

I thought about that as well, it would take a combination of simultaneous failures, which could happen, but its rare, especially twice.

The older models you could manually activate the fuel shut off by hand so even if it failed you could start and stop, these are not as easy to "manipulate" on these newer models.....

Thanks for the info. I'll inspect in the morning. While in for service, I'll be sure to get the updated part.
