Hello all!

This is a Model L we found in our property. It took a whole day of moving branches and other stuff that covered it before I was even able to find out what it is.


The engine doesn't look too promising:

It's so heavy that I will have to work on site. Not convenient on the slope the crawler is stuck in.
You can see the radiator is broken, the whole thing has been ripped off the tractor (still wondering how they did that!) and was found a few yards below:


I will post more!
And will ask A LOT of questions and hope to find help in this forum :)

It seems like it hit a tree (the property was an apricot orchard long time ago) as the trunk of the tree seems stuck under the engine.
My guess is a moron hit the tree, bending radiator, backed-up finishing the radiator that partially stayed stuck on the tree, moved forward again for some reasons (radiator is bent and I found a piece of the side cast under the crawler) and died there. It probably stayed like this for 15 to 30 years, hard to tell.

Some of the work that has been done on the engine and other things such as the tape used to wrapped handles cannot be older than 25 years IMO. For instance note the magneto and decently new ignition cables for two of the cylinders. They look better than when I found them yesterday as I sprayed some oil here and there to prep the work that will take place these next weeks.

I already really like this machine Smile

Am I right to believe that it's been simplified to crank and start manually? 
I cannot find any battery fitment, cable nor alternator. There seems to be a starter motor (and would be small though) on the left hand side but nothing connected to it.
I believe the Fairbanks-Morse magneto is autonomous and doesn't need supply to generate sparks. This last point is encouraging as it will minimize the parts needed to restore the old guy!

So first questions:
- Where would a battery be located?
- Do Model M normally have an alternator? I'm guessing yes, as some accessories seem missing on the right hand side of the engine. Also how would these gauges be fed? There's a bunch of wires going to the engine compartment.
- The magneto has a wire out. What can this be for? It's the blue-gray wire bolted right under the ignition outputs.
- Throttle. It goes to a mechanism on the front right hand of the engine. Seems to be managing ignition advance?? I would expect the throttle to manage the carburetor however there is nothing but a cable looking like starter choke that goes to the carb. Can someone points me to some technical docs about the throttling system?
Shocked
Thanks a lot for any help!
Luke

First off, without radiator on and hood, an fan bent to Censored, the old critter looks bad... but its and orchard model so it going to be a great piece to restore.
Behind the fuel tank you have gauges, if you got an amp gauge, then you had a generator on it at one time. starter is down below...
 one wire from mag is probably the kill wire (to ground the mag) which they all came with new, seen a few"mags that were actually electric enrgzed but those are very rare to find and usually were wico units...
 The generator was driven by the pully ahead of the mag, and the generator sat backwards. If I remember right the gen bracket was bolted to the head. the sparkplugs and a side cover that covered tem and was held on by the 2 studs that are in line with the plugs.
 Throttle lever linkage rod goes to the governor, and the governor control arm then goes across to the left side and back to the carburetor.
   There is AC MEL that on here and he lives in N Ca.  He posts in the construction part of this forum.  JC

Looks like a orchard tractor (rare find) IMO it would be worth hiring a big tow truck or find a local contractor with large dozer or trackhoe that can drag machine up out of that hollow to at least level ground to work on it.

Welcome to the forum. I think you found a dandy. Do I see both fenders in the pics? It looks fairly complete compared to some projects we seem to collect here. Please keep us posted on your progress.

Man that is one cool piece of A-C !! Before you go wrenching, please,do what it takes, whatever the cost, to gether up next to the barn or garage ! It really it THE FIRST STEP to what will be rewarding project. Then plan to build a 'temporary'(haha) lean too shed to keep the rain of her and the sun off you .Having it real close,under a roof will make it a pleasurable project as tools are close by,lots of shade,water, volunteer helpers.If you work 'down there' you'll lose your favorite tools under the belly of the beast,curse when yo draw blood and the badaids are 500' away. With it being 'close to home', tools are close too as well as pen and paper, manuals, camera,storage for all the parts and a comfy chair to plan the next days 'adventure'. It cost me $500 for studs,plywood and tin to build the 9by12 sheds for my D-14s. Money WELL spent as each is out of the elements.
Just food for thought

I think that is a model M orchard.  The model L was a six cylinder 844 cu. in. crawler, a much larger unit.  Norm Meinert may have any parts you may need.  Good find and may be worth restoring.

Brings back memories of the U I redid about 10 years ago. Guys on here will have most any part you may need and info here is top notch. I'll post some pics when I get a chance of my project that shows what you have there can be made look new again.
Keep the updates coming.

I'm assuming this is an L crawler, even though the title says M?
Either way, you CAN fix it!! 
Like the others said, I highly suggest getting it out of the trees and close to home. Trust me. I've tried doing the whole "fix it where it's at to save time and money" thing. It didn't work. Only difference was my project was a All-Crop harvester, and yours is a crawler.

Crestin, theres a slight difference between an L and an M... the L only weighs 22 thousand pounds while the M hefts out at 68 hundred pounds... LOL

If the tracks or clutches  aren't rusted solid you can pull one of those with a good 3/4 ton 4WD pickup without any problems.  

I've moved mine around the yard that way before.

That is really cool!  Welcome!  What a way to join the forum!  I wish I was close to help work on that beast.  Good luck and post more pics!

Hi Folks,
Thanks for the info and supportive notes.

Not much progress as I have been busy wrapping up other things.

I tried to spin the engine though, and broke a couple levers. So either clutch or pistons are stuck. Probably both :)
The gearbox seems to play a bit. This weekend I will try to tow it and open the top of engine to see how it is. Oil level is below minimum so I guess upper engine went dry for a long time.

When my dozer died on the pipe line (Not a good place for the gass company to see you with a dozer)  We hooked up a Ford 4000 to tow it somewhere i could work on it. It pulled it in a straight line fine but trying to work the dozer around a corner with the steering clutches really made that Ford notice something was back there. Its an International T5 a machine about the same size as the one above

I'm betting those tracks are rusted pretty close to solid,might be a bear to get moving.Bought a HD 5 once that'd been sitting for years had to drag it on the rollback tracks wouldn't budge.

You may want to take a pump sprayer with you and start spraying down the tracks with diesel fuel and used motor oil just to start loosening things up.

He hasn't been on here since 18 Sept of 2016.  He joined 01 Aug., 2016.  So, he was only on here for a month and a half....
Doubt he did anything with this.....sad.
