Going to an auction this weekend with a 1932 Cat Motor Grader, gas. Single rear axle, dual wheels, engine frozen, has a cab. Just looking at it to tinker with but it may be too "big".

Does anyone know:

Approximate length
Approximate height
Approximate width
Approximate weight
Model Number
Value
Any other info?

Thanks in advance!!

Forcus this is just a rough outline of what you are looking at as there is no Serial No to work with, the Serial No I would expect to see on this old lady would start with 8A1 up,
Lenght over-all 252"
Height 127"
Width 88"
Wheelbase 193"
Weight without Scarifier 13,412 Lbs
Engine Bore 4"
Stroke 5 1/2"
RPM 1,100 with full load.
Price in the UK, Big Money !!!!! this grand old lady would be a very expensive thing to buy in the U.K. it must be a rare item even in the U.S.A. its old and one of the first graders built with all the looks , history, including great engineering, go for it this is as good as it gets,

TC, the serial number book does list it as an 8A & it,s listed as a 9 Auto Patrol & started production in 1931.

S.J. some time ago I bought 2 ledgers of a good size with all the parts/opps/repair info for Graders from the first terracers upto the 66/77 models, they are genuine CAT Ledgers for Early Products, full of every detail that is worth knowing, sadly they are wasted on me as I never get a chance to work on any Grader other than modern stuff. but I live in hope,(perhaps I should pass these books on to someone that has a good interest in Graders)

Thank you so much for the information guys. I had no idea it was so heavy. This precludes using a 3/4 ton truck and 12k trailer as I had intended (it would barely fit on anyways). Sounds like it is semi time.

I am hoping to get it for under $500. We will see.

Should have the same engine as the Model 20 crawler. With scrap metal prices as they are, could hit $500 fast. Hope you get it.

Thanks!! I hope it goes well. We will see. Forecast says cold (~30 at auction start), cloudy, rain / snow flurries - perfect weather!

That Auto Patrol has possibilities! GWH

Thanks for all of your help guys! Bidding stalled at $600 and I snagged it for $700. The scrap guys weren't willing to bid higher (good!)

The engine appears complete with magneto and adapter. The cylinders are probably rusted from the humidity (the carb was open, but is a sidedraft and the exhaust had a vertical opening) so I am going to fill them with Kroll / PB Blaster / MMO / diesel and hope for the best. It appears to be hand crank only, but there is a place for an electric starter on the flywheel housing, so I will be fitting one before attempting to start it.

The controls all move though they are rusted on the outside surfaces. The wiring needs replaced. The cab was cut in two for transport at one time and then tack welded back on - no biggie - much of the metal needs replaced anyways and I am going to remove the top half for transport. Several of the original windows, molding, etc are still there so I can use all for templates for the entire cab.

The drivetrain / wheels appear to move / roll and all have air except the front right tire which is torn. Unfortunately they are all split rims, and in poor shape (from rust), so I am afraid of working on it and I don't think any shop will touch them. I am trying to get a tire shop to come out to just put a tire on, and fill it with a few PSI just to keep it seated - that will make moving much easier. Plan right now is to have the wheels customized / rebuilt with a conventional bead and install correct tires. It isn't original but I will take safety over originality any day of the week. I had a split rim on an IH pickup with 12k original miles that exploded - the rim itself had rusted on the inside and weakened and it gave way instantaneously. Had I been checking the air in the tire I probably would have been killed. I don't mess with no split rims I'm only 25 so I've got some years left.

I recorded the SN's but they are in my other coat. I believe the machine SN was 8A121 and the engine SN was 9A201, but I will have to verify (verified).

The only snag is my shop is wide and tall but the doors are split and are 8.5 feet wide and 7.2 feet tall. The tractor is 9.5 feet wide (with the blade where it is) and 7.5 feet tall at the cab cut. It will have to be outside but will be covered. Plan is to cut the shop supports (it is wood) and raise it around 3 feet (or more). This needs to be done for the car lift I am planning on putting in anyways But not til next year, at least. In any case, will have to work on it outside. I'm in town but the neighbors will not care.

Now I am on the prowl for books. It looks like the operating manual and service manual are both available as reprints but I do not know if they contain part numbers (which I can look up here at work). Will just have to order and pray!

Forcus, if you have a digital camera, we'd all like a look at your project from time-to-time. We don't see enough graders on this site, and an old Auto Patrol restoration would be just the thing to watch! Good luck getting it home. GWH
