Been wanting a big wheel case for quite some time.  A friend had one a couple years back but we couldn't get together on price and he finally got an offer he couldn't refuse and sold it - after offering me the first chance.  No hard feelings here.  He had spent a bunch of money on that tractor and that put it out of my price range.

Two months ago he calls outta the blue and says "you still want a 400 series Case?" and offers me a deal that I knew I wanted right over the phone - sight unseen.  I played it cool with "I'll get up that way and look at it sometime later this week or early next".  

He got the 446 in a package deal with an Allis Chalmers WD45 tractor and let me have the Case on the cheap.  Not sure if he made any money but don't care.  He priced it at $300 and said I could take it and make sure it was good before I payed him and if it didn't check out I could return it. 

When I saw it I knew what a deal it was.  I payed him over a month ago but couldn't get lose to pick up until last weekend. 

The story was it "overheats"  Thats all my friend knew as to why it was parked.  The overheating is a severe "Case" of vapor lock.  If I leave the hood open it runs perfect but close the hood and it won't mow more than 7 or 8 minutes.  Otherwise it is a very nice rig.  No holding valve and I live on a hill but its too small for me to mow with anyhow.  Paint is all original except rear hubs and lug bolts.  One rear tire would go flat overnight but it was just leaking at the bead.  Broke it down and soaped the rim and it hasn't went flat since.  Steering is tight and it runs the best until the vapor lock kicks in.

Is that a late 70's model? Take the tins off the onan and give it a good cleaning. Check to make sure it's fuel and not coil going bad.

Yes you got a great deal on that one! Congrats on the Case!

 

I think Gopher might be on to something with the coil idea. And if I remember right, I have seen where you can mount 2 separate automotive (Ford) style coils in place of the one coil with two plug wires coming out of it. I know I saw something on this before?

I took the tins off and no blockage found.  When I first revved it up some mud daubber nests let lose from the flywheel.  :(  It seems to be blowing past the cylinder heads very well.

They [PO] have taken the coil out of its nest and mounted it to the firewall leaving the hole open and also wrapped the coil in something like tin foil.  The exhaust shields are in place.  When it dies I can open the hood and spray carb cleaner in and it will fire right up.  If I spray the fuel line just before the carb with carb cleaner to cool the line it will stay running.  

 

No idea on the year.  It has a serial tag so maybe I could 'cypher it?

Hmmm... you could do like we used to for drag racing. The cheap "cool can" Coil metal fuel line in a coffee can and fill it with ice. The colder the fuel the better it atomizes, and it would cure the vapor lock :D  Probably no room for a can though :(

Welcome to the Case world. The serial # is the most important thing to know about Case tractor's, so you have the right information about your tractor. Funny statement about "overheating is a severe Case of vapor lock" only the second time I have heard about it and I belong to a few Case forums and rarely have seen it, look into something that isn't factory. Both of my Cases run like they came off the floor yesterday, which was 30 years ago.

That's a sweet deal on a great looking Case. Could the engine be running lean which makes it run hotter than normal. When mowing this would lead to over heating pretty quickly. I'd still remove the tin and check for obstructions in air flow as well. With that tractor in such nice condition a thorough check of the engine would be worth doing to prevent having an engine failure down the road.

Looks like a great deal and a great tractor you brought home. 

 

Just out of curiosity, the hood isn't pinching a hose when it shuts, right?

What a deal! :thumbs:  Hope it doesn't take much to figure out the issues. A guy up the road from me has a 446 and a I believe a 448. It usually makes me a bit envious when I see him out with his.

dad has a allis 720 with a 20hp onan. runs great until you start to mow then dies. we put a electric fuel pump on it and that solved our problem, so I would check fuel.
