Interesting @Harry , but my 644 doesn't skip a beat even with a bucket full of sand or gravel. I've done this quite a lot last summer. But I always use it in LO range. Except when I moved sand with it, full bucket, full trailer behind, and almost 500 lbs of weight equipped on the tractor. Total weight might have been close to 1000 lbs. There was a 200 ft stretch going on a slight incline uphill, then the K321 was struggling, but I made it slowly to the top. I wonder though, what the limitation of the hydraulic pump , or hydraulic drive, or TCV pressure relief valve is.

The valves and seats are nicely done now, clearance adjusted. New gaskets in a lot of places, got a full set from eBay the other day.

I'm kinda sorry to put it in the loader, seems like wasted power. :hm: Not sure at all what to do with it.

When I first purchased it the guy gave me a repair shops invoice that read what they did to rebuild the engine. Quite extensive with boring oversize piston new rings ect. At first never having a lbh before I took it easy in it to get use to using it. Last years I used it a lot and was not babying it at all. I use it in low gear unless have nothing in the bucket just traveling to get another load. I did get it stuck in the mud a few times because of the low hanging ballast weights. It usually just plows though the puddles but when the dirt is very wet it’s going to get stuck. One time I had to dump a bucket if dirt to push my way out with the bucket. :peace: Harry

I’m thinking of a 20 hp Honda that I have on the shelf in my shop for the 644 lbh. :peace: Harry

That 20hp Honda engine will make your 644 a beast! :thumbsup:

Thanks @JSinMO ! There are some tractors here with broken engines. Just thought this engine could go into something more special. There was a guy on marketplace selling a thermo king 3-cyl diesel engine and I asked if he'd trade it for the k361 but he refused me. :124: I'd have wanted that diesel engine for the tracked trencher. I think the k361 is a little underpowered for the tracked machine. I would want 20 hp minimum for that machine. There's a kohler magnum 20 for sale around here, that would probably be ok, but unless I sell something, no $$ :124:

Dave, I don't have a 226 anymore :(

I looked into the refer diesels , I don't like the way it add reads . Something is not right about that deal . Make your own K series 226 . out of a 22#

I saw the ad for the Thermo King diesels too... But I'm trying to convince myself not to get anymore "projects" until I have a house and a "REAL" garage...
