3rd picture, is that a C Farmall?
With a 6-71 you don't need to whine, it'll do it for you. I'd love to have one again.

WOW mschwartz, now that's some serious pulling power! who did the 6/71 conversion? love the cabs you got on them, all the comforts of home, is that a recliner you stole from the house on the last pic :lol: would love to come down and spend a day or so plowing with that set up. nice place you have there beautiful country.
Actually went and plowed with one in the last picture for a couple hours today, little wet but not to bad. Plowing some old pasture that needs
reclaimed. Using a John Deere 3100 plow with that one. The old 4R is hooked on to a case plow and the white cab D6 was hooked on to a
John Deere 777 plow. Was getting ready to plow with my sons last fall before winter hit us. All of the plows were five bottoms, not much of a
load for the cats. All of the conversions and updates are local farmer modifications. Seat in the last picture is out of a 60's Buick I think

Always love to tour eastern Washington and Oregon. Not used to seeing all the crawlers..some of the ground you guys work over there separates the men from the boys. Hope to see some more pics when you get going. Thank you, Paul

great pictures!!!!
Maybes short of easy starting, why in the world would one go from the cat engine to the Detroit in the old cat. Maybe could not find a 9u engine at that time or Detroit was cheaper. Just wondering.. Down here where we are the direct drive 9us are setting in the fence row or have already been junked. And we were forced away from the mole-board plough by government several years ago. Soil washes away if we turn it over.

Nice pictures, neat conversion, I like that little hump in the hood gives it a nice sound I bet!

Nice to see someone else keeping the old crawlers in operation. With the air intake high, looks like you get into some dusty areas. In the 30's to 60's all everyone used in California where I was raised, was crawlers for ground preparation, and planting. Stan
It was converted in the early 60's so probably before 9U motors were common replacements. During the late 80's it was still common to see farmers repowering 9U's with 1673's and running them for another couple thousand hours. Almost obsolete now though, production farms have gotten larger and so has the equipment. Steel tracks replaced by rubber.

If i never have to listen to another Detroit will suite me just fine . Company i worked for when i was a kid had some equipment Detroit powered . we had model C and D LeToneeau pans Detroit powered and we had Euclid pans and rock trucks Detroit powered and some old A C dozers with Detroits in them . All four cylinder ones has 2-71 manifold sporting Dual exhaust pipes and NO mufflers all 6 cylinder ones sported three 2-71 manifolds and straight pipes and the same went with the Euc.'s and if it was a 8 cylinder then four pipes and then there were the couple with the V 12's and they were refereed to as the Organs Ya want cured to the straight pipe issue just spend three months 10 12 hours a day 6 days a week weather permitting running a C Le torneu pan setting next to three 4 inh straight pipes 42 inches long with your foot flat on the floor keeping the engine RPM's up so you have electric to run the functions of the pan then multiply this time no less then four on a job and sometimes all the C and D's on the same job . Everything had multipl exhaust pipes , if you could not use faactory manifolds to split the exhaust system thenextra flanges were added or homemade manifold were built . The owner like LOUD and like to see smoke rolling and dirt moving
Ag work was the original purpose for crawlers or the most common application.
Looks like all are wide gauge with the widest track pads.
The older 4R, would have originally been the 3 cylinder engine, D6600 ? I think. So did the 2H and 5R.
No blade trunnions on these, track idlers are smaller and allow easier turning, best suited for drawbar work.
The 9U& 8U platform, wide gauge/narrow gauge, was a best seller for Caterpillar. I think they sold more 9U's than any other tractor, though the 3T, 4T D7's went over 50,000 tractors. I'm wondering if any of yours have a dry clutch, somewhere in the first few years oil bath clutches were standard, and they did offer a kit to convert dry clutch tractors over to oil bath. Direct drive, oil bath clutch tractors were a trade mark bullet proof design that carried well into the D6D series, which is still desirable today.
Over on ACMOC, there used to be posts of similar or the same models of tractors working in this area. You could get direct drive/oil bath & starting engines into the 70's, not sure when the direct drive and oil bath was phased out.
Cool to see yours still in service.

mschwartz, Thanks for the great pictures. BTW, If you're interested, a "neighbor" of your's in the Palouse region of Idaho (handle was NIF) used to post a great number of photos either here or on New Ag Talk of using Cats on his farm for tillage and planting. He even had old pix showing crawlers used for harvest due to the "vertical" nature of his area
(beforesidehill/hillside combines). Not sure if a search of either site would turn them up as it has been several years since I've seen a post from him. IIRC, he grew wheat and edible beans. Good luck and thanks again for the pictures.

Hello, the original 4R motor was a small bore six cylinder, I think the 2H was the last of the three cylinder models. The 4R has dry clutch still the others are wet clutch tractors. The 4R and the '58 are SA ag tractors, the white cab one started out life not as an ag tractor I think because it is geared way faster than any other ag tractor I have been on, second gear is working gear most of the time. Turning up the rpms's must have been part of the Palouse overhaul as these both turn 1750-1800. The '58 had a hard nose and a cat angle blade on it when I got it, helped the owner move the blade over to a D5 before he gave me the 9U. Sure a lot of history if old tractors could talk!
I always forget where the 3 cylinder tractors ended, they have a nice sound to them. My old D7 is geared a bit high, something about the ratios in military tractors is slightly different. I'll bet, with all the years in service, lots of history and one of the most reliable models they offered in that era. They last a lot longer doing ag work, not nearly as much backing up and turning.
