A cheap 1782 followed me home. Tractor and deck (appears to be newer series Haban) followed me home tonight.

I've wanted one of these for at least 15 years, since seeing on at a tractor show as a kiddo.

Previous owner said 2 cylinders were ~150-200 psi, and it runs but something is wrong. Guess I'll be pulling the head as the weather improves. Seems pretty clean, but the right side panel decal looks like it got warm. Any insight on these Kubota D640s having this issue? Best case would be a head gasket or valve issue...worse...a head/rebuild.

New battery is worth about 25% of what I gave for it. :beerchug:

Looks like it followed you home on a trailer, was that part of the deal?
Those prices in the picture they appear to be a BP petrol station. Can you tell what fuel is what price please?

That's cheap (Southern WI), the top line would be 3.65 by me. No, I've had my Karavan for like a year now.

Top to bottom: regular, mid grade, premium (gasoline), diesel, USD/gallon.

Those prices are super cheap , I am paying just over $7.00 for 4 litres Diesel which is a fraction more than a US gallon
That is a US gallon you still use ?

Honestly, I am Surprised it starts with 2 cylinders in the 150-200 psi range. New spec is somewhere in the 415 psi range. Minimum is in the 300 psi range. Not trying to scare you, but typically repeated overheats result in a cracked head. Usually cracks between prechamber and exhaust seat area, sometimes visually detectable. I would remove the glow plugs and verify compression readings before removing head, compression test is the most valuable test you can perform.

yes we still use a us gallon.
Here is a site we use in Michigan, one can look up any city or zip code and see gas prices.Yes we are blessed in the USA although California is just about double those prices.

I am not allowed to look at that site , it is blocked
We are stuck with a government who is influenced by the oil companies as to pricing , we have massive amounts of oil and gas but we derive no benefit as it gets exported
Sorry about hijacking the site to talk about petrol and diesel prices

I'm thinking that, then pull the head and inspect/get magnfluxed if it's not an obvious headgasket/valves.

I knew going into this it needs work.

You call it blessed, but in Spring 2020 I was paying $1.39/gallon. :bigthink:

Yessir, US gallon. In IL there's a large new tax which caused the disparity in WI (much cheaper).
