Northwest Iowa | I would like to hear all the good and bad of the tractor. Can this tractor turn tighter that the John deere 50-60's series MFDs? Would want to use it as a all around tractor. Would be spraying, sidedressing with it so would have to turn tight enough to be a true row Crop. I have stayed away from the JD 50- 60 series MFD because they cannot turn tight until you get to the 100 series. Hows the 7140 tranny, MFD and motor. Is the cab tight? Please give me all the advise you can. This forum has been great for me. Thanks in advance!! |

Windom, MN | had one and it was a good tractor. the turning radius isn't that good, but I've never had a JD to compare. We used ours for tillage, but the spray tractor went down and it pulled a 750 gallon 60'boom with no problems, and I'm sure it would handle a much larger one. Spraying, ours barely used any fuel, as we had a hydraulic pump on it and could idle way down. The newer 71 series had 4 reverses, and the older had 2. we had one with 2 and it was slow, but if I found a very nice 7140 with a 2 speed reverse it would not be a deal breaker.
Never sidedressed, but I think it turns sharp enough for 12 row equipment. our FC was a 30 footer and I didn't have any problems getting it turned around. |

Southeast North Dakota | I've got one and I LOVE IT! The mechanics at Titan Machinery told me to replace the injectors every 5000 hours and to always pay attention to the quality of the shifting. If it gets jerky or shifts hard in any way there are some shifting accumulators that might need to be recharged. Other than that they are bulletproof tractors. I can't wait to run mine; it's truly a pleasure. They're nice and quiet and have a nice "hum" while they are working. Mine is a 1991 model with 4 reverses and 4 hydraulics. Mine turns sharp but it's currently set for 22" rows and I haven't changed it yet to 30" rows. When that change gets made the turning radius will be DRASTICALLY reduced. When I get done side-dressing corn I will set it back to the wider setting so it turns better. |

| We have a '91 7140 mfd that we bought a couple years ago as a "mowing" tractor. WE have also owned other Magnum tractors in the past, icluding 7120s, 7220, & a 7240 mfd. Our 7240 ws a "horse" as is the 7140. Other than weight, it will hang right in there with our MX 275, maybe even have a little more hp. Cab isn't as roomy or quiet as the MXs but much quieter & roomier than the JD 4640 it replaced and way more power than the 46.
As for turning, we us to cultivate with our 7240 using a 12x30" cultivator and could turn back in on the next set of rows on 24 end rows and just tapping the brakes. Other than for rowcrop work we always set our front wheels so they split the middles of the rear duals when set for 30" rows, which is about 44" on the fronts. Then to do rowcrop work we just switched the front tires side to side to get to 30"
The 7140 is the 5th Magnum we have owned. Never have had tranny problems with any of them. Had to replace a couple sleeves on the 7240 but CIH warrantied the repairs |

frederick, MD | We have 2 of them with about 9000 or more hours on them. Great tractors. Good trans. Some had head gasket leaks. It wouldn't blow but would seep water outside. Get it good and hot and shut her down and look at the head gasket. You will be able too se if its leaking. Front hubs may leak oil. There is an upgrade that requires some machine work to take a better seal. Did mine years ago. But they are leaking again. But its been years. Also it can be a little short on cooling. Gotta keep the radiator good and clean.
They are great tractors. If they made them brand new I would buy 2 of them tommrow |

Owens Cross Roads, AL | I had a 7140 with a 2speed reverse, only problem I could see if you had a loader on it and to back up alot. For my use the 2sp was great, never backup fast when hooking up implements anyway. Wilson |

Eastern VA. No such thing as too many Magnums. | They're good tractors. They don't turn sharp. Hub seals, hitch sensor pins, and steering hoses are the most common problems, but are not very difficult or expensive to fix. Transmission is very tough and reliable. Cab is fine I think. Engine is real good. You can get parts anywhere for common stuff since it's a Cummins and it will be cheaper than a comparable Deere engine. Price a waterpump for instance. We have six of that type and I think they're the best tractors ever built. I think they'll be running when the 275 Magnums and Deere 8330s are in the scrap yard. I would try to find at least a 1992 year if it was me. Look at the S/N tag down by the clutch pedal, try to get one over serial JJA0039000. Don't rule out a 7240 or 50 in your search. They had a lot of improvements.

Northwest Iowa | Thanks for all the replies.
Virginia Veg,
The one i am looking at is a local tractor with 10,000 hours on it. The owner rebuilt the engine 3,000 hrs ago. I am going to look at it tommorrow. It is a 88. Is that bad. I dont know much about them except that the cummings engine are good. We had a Case IH dealership until a few years ago. The shop mechanics kept the shop open so they will be a great resource. I asked them about them a while ago and they said that is they had to make a living fixing those tractors they would starve to death. Please tell me more on the upgrades that they did.
I will see how the tranny is tommorrow. |

| I have a 7140fwa and echo the others favorable sentiments about the machine. I can't compare it to a comparable Deere due to my inexperience with those. I have seen it described here as a bull in a china shop. Not a bad description.......it is not too nible. With that aside, it is a great tractor. Every one I have seen has a 18 speed powershift. It is bulletproof. For advice, check the belly for oil leakage. There is a main seal gasket that, if you have a bad leak, you have to split the tractor to fix. |

| We have a 7120 and a 7140. We have done some work on both, but both tractors were cheap Southern Belle's and the repairs didn't break the bank. Good news is that if you DO happen to do trans work, it will be less than half of what the comparable greene powershift will cost to repair, ditto the engine. As to turning radius, if you are using 12 row equipment you will be fine, it sort of depends on rubber. If you run narrower front rubber, and lock the oscillation stops down a little, you can cheat the wheels out and make it turn pretty good. We currently have ours set on 80" centers, because it never does in crop work, and it rides great and will turn sharp enough to run a 15 foot drill or cultimulcher. |

kuna, Id | It's the only tractor that I care to own. We run a dairy and grow our forages and those tractors are pretty adaptable to whatever task we are doing. The engines and transmissions are pretty much bullet proof. I think they have just the right amount of electronics regarding engine/trans protection, sometimes when we are busy we will throw some inexperienced help into one of them just to get stuff done and it's some comfort that I know the thing will just shut down before they blow it up all together, yet it doesn't have all that computer crap on it to create additional problems. I buy them already half used up and then we run em some more, out of six tractors (all Magnums) over 12 years I've replaced one head gasket and a transmission. both on the same unit bought it with 11k hrs gots 18k hrs now. All the other stuff has just been minor repairs starters, alternators etc. Oh, and the head gasket was caused by one of my guys not filling it correctly after a radiator hose change, only got it half full and air locked it. Turning radius is an issue but if you are running 12 rows then you will be fine...we do it :) I like them so much that i got a standing order at my dealer for used ones in my price/hrs range. I won't buy a new one, and I know many others that feel the same way. They are the best horsepower for the money! |

Eastern VA. No such thing as too many Magnums. | A lot of dairies and vegetable farms like those tractors. That should tell you something, since those are the type of operations that generally don't baby their equipment. An '88 model year wouldn't be my first choice, but that doesn't make it bad. It's going to have a 2 speed reverse and it won't have the auxillary hyd filter down by the right rear tire. They had some engine issues in the very beginning, but if it's been rebuilt, that should be taken care of. I didn't care for the hydraulic seat, I can't remember when they switched to air, but by now either one would probably be worn slam out. Otherwise there's not a LOT of differences. The 72 series had better flow controls, slightly different hitch controls and outside hitch controls, easier shift detents, upgraded MFD seals, auto MFD with brakes to help turn sharper, and a button on the dash to more easily see the engine hours. None of the changes were earth shattering, but all together amounted to a little better tractor. There are dozens of other things that were improved, but some of them were also on the late 71 series. |

Wallis, TX | I had one of the first ones ever sent to TX. Had lots of problems, probably most were eventually fixed/updated but a real pain in the day. I'd look at the later models unless you can confirm all updates have been made.
Updates I can think of, hitch pins/wiring harness/potentiometer, possibly more than once, front engine cover/seal and early A/C's liked to spit water on a humid day. Fuel gauges liked to go out, IIFC it was normally the bottom sending unit and some dashes were replaced which would mean hours are not right.

Southeast Florida | They increased the front planetary hubs on the 40 & 50 about the same time they went to the 4 speed reverser. The original 7140's would break the 3 pin hubs on the front axle when they weighted them down enough to hook up. The decals are different if they have the original ones on the s/n break. 10,000 hours, OK it good and broke in; I’ve seen them down here in the sugarcane fields and dairy’s with 30,000+. Rafe is by far a better expert on them than most anybody I know but this is few things I know. |

Southeast North Dakota | My 1991 model has a serial number around 041000. Maybe mine is a 1992 then? |

Southeast North Dakota | One thing about being an '88 model is it will be an insane powerhouse compared to a newer one. I was told by Titan Machinery mechanics that the earlier 7130-7140-7150 were all cranked up from factory. I know about 15 years ago we rented a 7130 MFD and it would way out-pull an 8940 MFD that we rented the next year. I think those earlier ones would be fine also. |

Eastern VA. No such thing as too many Magnums. | 39300 was the first one for 1992. |

Southeast North Dakota | Wow.....Mine is a 1992 then. I just looked at my serial number the other day and I remember it was in the 41000's. Thanks for the info! |
