Oil & Fuel YM2500 Pushing Coolant Out the Radiator

***UPDATE 07-24-2025 Thursday***

The head gasket and related parts arrived today. Will be dropping the parts off to my mechanic tomorrow (Friday, 07-25-2025). I don’t like that it’s made in China, but it is what it is.
The new, loaded cylinder head was also made in China.

I have a question:

Does anyone know if the Head Gasket for the John Deere 850 is made in Japan, if ordered through John Deere?

As most of us know, the John Deere 850 compact tractor and the Yanmar YM2500 are basically the same tractors. They both share the same Yanmar 3T80 engine.

Thanks,

Travis

That would be interesting knowing JD. parts could be made in china. Or are!! Does seem to fit though. Esp. this thread ? Was it a tractor imported from there. Sure looking like it. Still don't know if the head is good? Was it in that bad of shape the had to replace it?

I dropped off the Head Gasket & related parts this morning to my local mechanic.

He said the cylinder head will probably be back from the machine shop today.

Once the tractor is back together, my mechanic is going to let the engine heat up and cool down several times then re-torque the head bolts.

He’s supposed to fix the throttle shaft assembly before he installs the cylinder head.

He showed me the engine block and cylinder sleeves and said he was real pleased with both.

My mechanic said the new cylinder head had “gouges” in it, and that it had to be sent to the machine shop to be milled down and checked out to make sure it was “true.”

Good luck!

I did some researching after I bought the tractor from Fredricks Outdoor.
They had it up for an Auction Sale on TractorHouse.com in December of 2023. I purchased it from Fredricks Outdoor on 11/22/2024. It states that it sold for $3,100 US dollars on 12/23/2023.

Yes, there is no doubt about that.

I would of not bought the machine if watching the video prior to sale.

When the throttle was tapped a few times, thick black soot blew out.
This tells me the engine was not gone over at all during the restore process.
Just new paint, seat, hoses, radiator and exhaust pipe. If this was the case, the $3,100 USD bid should of taken it 'as-is' with limited days or no warranty.

I think what this is telling us is Fredricks bought somebody's VN refurb at auction, in the US, for $3,100 to clean up and re-sell.

This isn't the same thing as getting used low hour trade-ins from Japan.

Fredricks Outdoor is the one who had it for sale, at their dealership, after the “refurbishment.” through an online auction on TractorHouse.com and it sold for $3,100.

Why did it sit on their lot for 11 months, after it sold through the online auction?

The auction video of the tractor was taken at Fredricks Outdoor in Decatur, Alabama.

The tractor “sold” in the online auction in December of 2023. I purchased the tractor in November of 2024, at the same location the auction video was taken, at Fredricks Outdoor in Decatur, Alabama.

When I purchased the tractor in November 2024, I paid a LOT MORE than the $3,100 that it sold for in the online auction and it looked exactly the same as it did in the online auction video.

Something just doesn’t add up. It’s very fishy.
