After sitting mostly idle since 1987 when the farm became part of the conservation reserve program (CRP) I was able to put our 7U D4 and 5U D2 back to work. Most of the effort was on the starting engines. It turned out that the carb & mag rebuild of the D4 was probably not needed (but thanks to the group for good input on the process). The problem was mostly a sticky governor. The motor would start and the governor would close the throttle and stick fully closed. I took it apart and used a .22 rifle cleaning brush to clean the shaft and bushing and haven't had trouble starting it since. The D2 wasn't run at all for 10 years and had a lot of rust in both fuel tanks. Once it was running the governor would surge. After buying the O&M manual for the D4 I realized that the injector/governor housing needed oil. No one alive associated with these machines ever recalled seeing this service performed. I flushed injector and starter gear housings on both machines with kerosene and refilled with oil. The D2 needed a fuel filter change along with the normal oil and air filter service on both machines. Both starting and main clutches on the D2 needed adjustment, but with the manual in hand this was a very quick job.

They both run great now. They ripped up 165 acres of dry farm wheat land that had been left in wild grasses and sage brush for 25 years and will be used to cultivate and plant this ground in about 4 months.

The operators in the video are 5th generation from the homesteader and original buyer of the tractors. I'm hoping they'll still be going in 12 years for the 6th generation.

thanks for posting, gotta love those drawbar farmcats! I think the manual reads start machines once a month to keep lubricated. Good luck with'em.

Good for you guys, keep at it. It looks like that sagebrush is giving you a hard time. Our ranch has not been farmed in about the same time. It was not in CRP but could have been. We have been running cattle. There is a 4'-5' stand of coyote brush, thick in spots. I am chopping with a D2 5J with a PTO Sidewinder, and plowing with a D4 7U and 4-14"s, turning it all downhill. It is covering well but it is kind of dry, am breaking plow points.

I am 4th generation, while I am working I think about my great-grandfather grubbing brush by hand and plowing with a team.

I'm also 4th generation on the land, though I live 100 miles away and make a living as an engineer. My great grandfather used a single bottom plow behind a 2 horse team to break the ground. Later he bought a steel wheel Fordson then gasoline Cats, first a Two Ton, then a 20 and 30 followed by an RD4. I think there was a D4 and D6 along the way but the only Cat of his I ever saw personally was this D2 purchased just before I was born. I have a photocopy of a photo of him on the Two Ton. He farmed into his 90s. My dad tells a story of watching him drive the Cat around working the field, stop, get off, pull a hammer out of the fender tool box and start pounding in the dirt. It was a rattle snake that he killed with a ball peen hammer!

A century ago, most of the sage brush was first burned on the stump.

I figured I could also spot burn the big sage brush by first spraying with diesel then lighting it with a propane torch. I even bought the pump up weed spray cans for the diesel (figured I could use the rusty fuel in the D2) and a pair of 500,000 BTU/hr propane torches. My dad asked the fire marshal and he said it was ok from a fire safety factor at that season, but that you needed a state air quality permit. The DEQ process required sending the application payment in advance. If approved they'd call you ~24 hours ahead of time, but they said don't call us, we'll call you - and don't expect us to call you. Basically you can't burn fields in Idaho from my reading of the DEQ brochure.

In the thicker areas of sagebrush it would pack in the digger tines. Since we have no hydraulics on these machines we'd have to dismount, climb up on the digger pull the digger out of the ground by unlatching and pulling levers, climb back on and back up a few feet, hop off and unpack the brush from under the implement. It was hard work. I'm taller and weigh half again more than my nephews (but they have more stamina) and it took all my weight, muscle and leverage to pull the handles down at times - especially on a steep side slope. Often I'd have to pull out the upper side, make a U turn so the low side was uphill and do it again. It seemed to take forever to make the first round along the edge of the field. It would have been easier with our larger digger and hydraulics had we not lost the 84J D4D SA to an un-noticed cracked oilpan while dozing with it a few years ago. Ultimately we did get through all but the heaviest brush last summer/fall. I plan to use the D6B blade to scrap off the really heavy brush next year. Most of the field looks pretty good now, but I don't know how the combine will fare picking up sagebrush remnants.

Two years later I've had two harvests of spring wheat from this land. It wasn't great the first year. This year would have been pretty good had it not been for monsoon delayed harvest and a last storm with hail. Compared to where I started in 2011 it is looking like a nice wheat field now.

The old 7U and 5U machines are starting easy and running as good as ever. My cousin who owns the land I'm farming just bought deluxe new seat sets for both machines.

Good to see the old machines still earning a keep.

I have the same tractors and I am amazed at the speed you have them both working. I guess the 5th gear in the D47U is there for some purpose afterall! I am yet to get mine into 4th, but then again it has loads of extra weight from the blade, ROPs, winch and track guards etc compared to your machines. I presume field work is probably what they were really designed for?

In the video at 29 seconds to 35 seconds, the tractor is running so fast that the tracks aren't turning but the sprockets sure are! (at least on my computer) 😆

The CRP is in essence a farm subsidy paid by the US Federal Gov. Rather than paying to produce more than was needed they selected areas with steeper more erosion prone ground and offered 10 year contracts to plant wild grasses. These were renewed twice for shorter terms. As I recall it was a bidding process where one land owner would bid for example $40/acre per year and another say $43/ac. The program managers started with the lowest price bids and worked up until the money was all committed. The land owner would have to plant the wild grasses, keep noxious weeds out, and often keep cattle out. Many of the states in western US are "free range" states, meaning you have to fence out the neighbor's cattle rather than them having to fence their cattle in. Anyway the CRP ended up being the retirement plan for a generation of farmers. In reality it didn't pay much more than property tax, spraying weeds and fixing fences but it did take much of the labor burden off the retiring farmers. It is amazing how fast some of the land went wild with sage brush or quaking aspen encroaching the land. Most of the land we have is still in CRP, though some less steep sections are now out. Of those, I'm running one piece for one cousin. Some other cousins have some of my grandfather's land that just came out of the program. My dad's land is the steepest of all and is still all in the CRP.

I'm middle-aged now and was just starting an engineering career and family when this started. I have mixed feelings about it. My boys all grew up, went to college and started their own careers and families while the farm was in CRP, so they never had the experience of working the farm. Some of my nephews have caught a small taste of it, but not the full growing up learning how to work hard until the job is done tradition. It was a really big job getting rid of the sage brush, though not as bad as my G-Grandfather who did it with an axe and a horse and plow before Cat's were invented.

Yes I think the 5U and 7U machines were really designed for field work. And no, we've never run 5th for anything other than transport. It is probably 3rd, maybe 4th gear in the video.

My brother took the video on a first generation ipad. The refresh rate looks to be close to the time it takes to advance a track cleat from one position to the next. The D2 looks and sounds faster than the D4. It does run at a higher rpm but has to run at least one gear lower than the D4 with the same load. We never pull the disk with the D2, and the digger (small chisel plow) is really small.

The "Caterpillar Performance Handbook"
http://nees.ucsd.edu/facilities/docs/Performance_Handbook_416C.pdf
shows 10,700 lb rated drawbar pull for the 63hp 7U D4 (page 20-2) vs. 6680 or 7950 for the 38/43hp 5U D2 (page 20-1). Interestingly the D4D SA (page 20-20) at 68hp and 14270 lb machine weight had a max drawbar pull of 12750 lb vs. 12700 lb for the 7U D4 at 63hp & 10970 lb machine weight. The old D4 could nearly pull its own weight. Of course the D4D was faster at 2.5 mph in 1st vs. 1.9 mph for the old D4.
