question about CG

[Jason Epperson]

Yes with those measurements I would agree that it is a CG, actually a CGH, the H being for the Hillside or wide track model with 61" gauge. Both the CG and DG used the 7.25 pitch tracks and 5 roller track frame.

Thanks for all of the help with my crawler.  It's nice to know what I actually have.  Thanks again.

Now that we have concluded that the tractor is a CGH, What about the engine??  The original engine was a WXT, this was the early version of the wx series of engines.  The bore was 4 1/4" stroke 4 1/2" . That size later became the WXC3 when that series of engines was expanded.  The engine you say you have is a WXLC-3, this is a 4 1/4 bore by 4 3/4 stroke engine.  Now this engine was used in the M2 high speed tractor the US military used in WW11.  The M2 was made by Cletrac so it could be just a bolt in replacement!  The millitary engine had two canister type oil filters just above the water pump.  It also had a higher compression ratio of 6.5.

Robert, do you mean the MG-1 engine?

Th engine is a wxlc-3.  Says so on the tag on left side of engine.  It just has one oil filter though.  I had the head off and it has aluminum pistons in it but I don't recall what size they are.  The guy I bought it from said it was an old See-Bee dozer?  I thought maybe the original went bad and was replaced with this one.  The crawler is orange, no signs of olive drab.

Blake , I believe the MG1 was similar to a BG with a Hercules JXC . I have never seen a picture of a MG2 .

I think what some call an M2 is an MG-1. I think the MG-2 had the same engine, but I am not sure.

I know my BG has an MG-1 engine. I never heard it run, but I guess it would run pretty fast.

The M2 was a seven ton high speed tractor used to pull aircraft around the runway.  They are shown on pages 249 & 250 of  the Standard Catalog of US Military Vehicles 1940- 1965 by Thomas Bernt.  It used the WXLC-3 engine.  I don't know what the MG 1 is, mayby it just another name for the same thing.  It is not a big surprize to find a non original engine in an old tractor.  These things were built for work, not for a hobbiest to play with!!  I have a 1947 DG and a 48 for parts and alot of changes were made to them over the years!

The MG-1 is not the same as the M2. I also think that because somebody mentioned that a couple years ago. He  had the 2 series and it was built by someone else. Also Robert does that book show a 3 series? I understand those were larger yet and wer built by A-C?

I think the military designation for the MG-1 is the M2. Have to do some searching in the military section.

I don't think any of our family's Cletracs have the standard engine in them. My two E's I bought myself do, but most everything else is experimental and was used in developing tractors for the market.

I got the numbers off of the tag today. WXLC-3, 4 1/4X4 3/4,  181398.  I assume the last is the serial number.  Any way to tell what year it is?

[Albert Duroe]

Refer to the July/August 2005 HPOCA Magazine, page 22.  The correct name is; Cletrac Model MG-1, Ordinance Model Medium M-2.  The John Deere and the Cletrac model had the same name.  My idea is to call them anything you like, m1 or m2 or mg1 or 2.  Great article  (I wrote it)  Sparky Duroe

John, there were lots of high speed tractors, the M4, M5 & M5A, M6 and M8.  AC built them all except the M5 & M5A which were built by International.  The M4 & M5's were 14 ton units, the M6 was 38 ton and the M8 was 28 Ton ( smaller then the M6 ).

I came across this site the other day.  It appears very interesting.  I saw an inquiry on a model CGH.  I have one too, it has been resurected and painted up nice and sits on display in Orr, Minnesota.  It is still "usable" if it still had a "use".  I ran this cat a lot when I was a teenager.  There are some very interesting stories to be told regarding this machine.  It was used to skid pulpwood and sawlogs in the 40s, 50s, and 60s.  It is an old military unit from WWII, Olive drab paint still exists under the present paint.  This is a big machine, about D-4 size.  It has 18 inch pads and weighs about 12,000+ lbs.    I have never seen another one this size, a lot of them half this size, which look pretty much the same.  I still even have the operator's manual for it.
Hope someone else finds this interesting.
