Hi all. I found a pretty decent 1976 7040 that I've been eyeing up. The guy is the second owner, had it since 1990. The hour meter quit a long time ago and he guesses it has about 8000 hours on it. It is a power director transmission. Tires are fair, about half tread left. The good; it has been their auger tractor for the last 15 years and pulled a 24 foot grain drill on occasion. It has always been shedded, the paint and sheet metal is nice, it has a full rack of weights on the front, and the cab interior is in excellent condition and all the glass is good. It seems to run well and shift good, PTO works as it should. You can tell by the drawbar that it has not done a lot of hard fieldwork. Also has 4 brand new batteries. The bad; the hours are unknown, injector pump has never been gone through, tach don't work, not sure if the air conditioner works, there is a hairline crack in the exhaust manifold, and one of the hydraulic remote levers is broke or somehow became disconnected. The owner said he never bothered to fix it because it just ran the auger and only needed one remote for the grain drill. The price is $6500. It is way bigger than I need for my operation I know, but that seems like a decent price for one in this condition. Do I pass it up because of the issues that it has or do I buy it, even though it is bigger than I need? Any 7040 advice would be welcome. Thanks. ------------- '49 A-C WD, '51 A-C WD, '63 A-C D17 Series III, 1968 A-C One-Seventy, '82 A-C 6060, '75 A-C 7040, A-C #3 sickle mower, 2 A-C 701 wagons, '78 Gleaner M2 |

I think you answered your own question in the topic line.  on the subject of "more than you need": I have a .357 magnum I occasionally use for target practice. I'm sure a .22 would serve the same purpose and be more economical, but it wouldn't be quite the same, would it?! you want it, you can afford it, and as a bonus you will even get some use out of it. but I will let those better informed advise about relative costs of fixits. ------------- 3 Ford 8N's I loan to neighbors, but the '52CA, '41B and little B1 I do not. |

likewise you will get better advice on the how much needs fixed but as far as size... everyone always says, build a bigger shed, you always need more storage. so maybe too much power is better than not enough? ------------- Holding a grudge is like taking poison and expecting the other person to die |

| when I cut back to 100 acres on the farm, that's when I bought the 7080! only thing it did was disk. I had other tractors to do other things. 7 tractors all hooked to different things! I really wanted a 4x4 tractor, but didn't gits one bought in time! I would have one by now if'n I was still farming! |

None of the bads you mentioned are deal breakers in my opinion. I do not know the true number of hours on most of my tractors. If the injector pump is still working, don't worry about it for now. It's a 40 something year old tractor, there are always going to be some tiny little issues. Take care of a few at a time and eventually you will have it perfect. ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '63 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

Thanks for the replies. It's one of the nicer originals I have seen. I don't know much about the 426 engines except the horror stories about the ones in the early 7080's. I hope the lower HP 7040's were more durable. Have not bought it yet. ------------- '49 A-C WD, '51 A-C WD, '63 A-C D17 Series III, 1968 A-C One-Seventy, '82 A-C 6060, '75 A-C 7040, A-C #3 sickle mower, 2 A-C 701 wagons, '78 Gleaner M2 |

Why would you worry about the injection pump not having been done already? Like mentioned above, if it runs good, and doesn't leak, keep running it. The DM does not have the failure prone flex ring that the DB/DC has. Honestly, many times the pumps are "rebuilt" by less than qualified people, and really add no value to the tractor since many times they need rebuilt again by a true professional. I know I much rather work on an original pump than one that was "recently rebuilt" lol! ------------- 210 "too hot to farm" puller, part of the "insane pumpkin posse".

The fact that it has been shedded and tin is straight is a decent sign it has been maintained. If you can afford it go for it. ------------- 8030 and 8050MFWD, 7580, 3 6080's, 160, 7060, 175, heirloom D17, Deere 8760 |

A friend told me the first thing he checks is if when you grab a fan blade, can you move it back and forth? If there is play, replace the water pump before you need to replace the water pump and radiator. Is this a PS 7040? ------------- 2-8070FWA PS/8050PS/7080/7045PS/200/D15-II/2-WD45/WD/3-WC/UC/C |

It's a Power Director. The radiator was reconditioned and the water pump replaced about 5 years ago. It has mostly ran augers on a grain farm these days. The owner says it is the last piece of equipment that was his fathers. I asked him why not keep it for sentimental reasons and he said they don't keep any equipment for sentimental reasons. It sounds like it got upgraded by a John Deere, if you can call that an upgrade. ------------- '49 A-C WD, '51 A-C WD, '63 A-C D17 Series III, 1968 A-C One-Seventy, '82 A-C 6060, '75 A-C 7040, A-C #3 sickle mower, 2 A-C 701 wagons, '78 Gleaner M2 |

Personally, I think $6500 is a touch high, but not out of line. Minor manifold cracks are normal unfortunately, the hydro levers if "free wheeling, are typically broken ball studs, but even if a cable can be fixed for under $200 ish with a new cable, depending on where you get them. PD trans last forever, especially if it has been mainly a PTO tractor. The PD probably should be resealed if it is still original, but slippage will tell you that, and not a terrible job with the right tools. You are correct the lower HP levels weren't enough to cause any mechanical issues. ------------- Still in use: HD7 WC C CA WD 2-WD45 WD45LP WD45D D14 3-D17 D17LP 2-D19D D19LP 190XTD 190XTLP 720 D21 220 7020 7030 7040 7045 3-7060 Projects: 3-U UC 2-G 2-B 2-C CA 7-WC RC WDLP WF D14 D21 210 7045 N7 |

| I think that I may have seen this 7040 on craigslist. If it's the same one, how did it become a black belly 7040...? It is a good looking tractor though. Darrel |

That is the one Darrel. It began it's life out in North Dakota (Hillsboro I think) and has been in MN since the early 1990's. The owner said they didn't like the look of the maroon belly so they had it painted black. I'm OK with that. ------------- '49 A-C WD, '51 A-C WD, '63 A-C D17 Series III, 1968 A-C One-Seventy, '82 A-C 6060, '75 A-C 7040, A-C #3 sickle mower, 2 A-C 701 wagons, '78 Gleaner M2 |

Can you explain the broken ball studs please? Is it part of the cable itself? ------------- '49 A-C WD, '51 A-C WD, '63 A-C D17 Series III, 1968 A-C One-Seventy, '82 A-C 6060, '75 A-C 7040, A-C #3 sickle mower, 2 A-C 701 wagons, '78 Gleaner M2 |

| No there are on both ends of the cables. Take the side cover off the console and it is pretty easy to get at. The ends on the remote valves aren't too bad to get at either. |

Well I bought the old girl for $6000. She runs good but needs lots of tinkering. All of the electrical in the cab ceiling comes and goes as it pleases. The one remote cable needs to be fixed. Air don't work. Did I mention she runs nice? ------------- '49 A-C WD, '51 A-C WD, '63 A-C D17 Series III, 1968 A-C One-Seventy, '82 A-C 6060, '75 A-C 7040, A-C #3 sickle mower, 2 A-C 701 wagons, '78 Gleaner M2 |
