Funny, I sold him one about a year ago. Guess he's had enough of them.

Something like 6,454 6 cylinder W, WA, and WK-40 tractors, per C.H. Wendell were made. I have close to 200 survivors on my serial number search and I suspect I've just scratched the surface. I have 14 of them, myself. Certainly, "hundreds" of them are out there. Not a rare tractor but rare to find operable and with the correct engine and wheels. Getting very difficult to find decent original manifolds. These tractors on Craigslist are probably a good deal, just guessing, assuming the engines are correct. You can't rebuild a stuck rusty one for that.

You have 14 of them? I own one that I repaited that looks nice its a late 36 with cut downs on. Mine has the rd450. Do you know where I can find a manifold for a good price. rosewood michineing seems a little steep.

I am looking for a W-40 that my Grandfather bought new in 1937. I was told that it did survive the scrappers as it was sold from a junk man in Caldwell, Kansas to someone in Missouri in the 1960's. The serial number is #WKC 5981
Had factory road gear, rubber tires, lights & starter.

I've had two, both 36's. One's a runner on full steel and one was a fencerow tractor but had round spokes and road speed, I traded it for something else, then picked up a RD450 and now have nothing to put it in.
It's a nice tractor with a sound of it's own. It actually drives and steers easier than my I-12.

Ok, with my RD450 is the manifold the same as a 289 so if I can find an old factory manifold it will bolt right up? And if I do go with a Rosewood manifold, are the gonna be two small to let the 450 breathe like it should?

The common RD450 in the truck application included a 2 bbl. carb with a 4'' exhaust. The exhaust outlet on the FBB 298 kerosene manifold is 2 1/2" ID plus other internal restrictive cast webbing used on the heat riser mechanism.

If all you are going to do is chug through the tractor parade it will probably work out fine. If you are going to pull extended runs with a 4-14 plow and packer your Rosewood manifold will undoubtably change colors on you.

I would think you'd also have an issue with drawing the needed intake through the original K5 variant carburetor (K50-AY12 or whatever it was).
