Romeo, MI | How popular were these tractors? In our area there were 4020, 4320, and 4620. Never heard of 4520's till I started surfing web. |

Eastern VA. No such thing as too many Magnums. | They only made 4520s in '69 and '70. It was Deere's first turbocharged tractor. In '71 and '72 the offered the 4620. It was very similar. I don't thing the 45 had the option of the powershift. My uncle has a 4620 powershift and it is one solid old chunk of iron. |

Northeast Louisiana | Neighbor had one back in the 80's. I drove it some, but not much. It pulled a 21' 490 International disk very well. Was a great tractor for him. Only one I know of in this North Louisiana. |

| We had one and there were a few others around swmn. Were kind of an oddball tractor. With only 1000 spline pto and it took 20 acres to turn them around aren't much of a yard tractor. They are big tractor but under powered imo. |

Walnut Grove MN USA | Was that one of those that if you walked by it on a warm summer day with an ice cream cone you had better get the ether out or it wouldn't start? |

Owings, Maryland 38.6856 N 76.6752 W | I have one, a '70 model with syncro trans, powershift was available but gettin pretty hard to find one with PS now. '70's had some updated airfilters over the '69's is about the only difference. I understand that a bunch of 4520's went back to dealer to be turned into 4620's with the addition of intercooler ?????
It's a lumbering giant but it is only rated at 122 HP, a bunch of them were sent out with 18.4's and should of had 20.8's. 1000 rpm only pto, nothing wrong with that, I wouldn't want it on a 540 shaft, thats for sure.
For me, mr. small timer needed a bigger tractor, well bigger than my do-all 3020, 4520 does bushhoggin, stalk choppin and I try and chisel a piece of land every now and again, also drag a 750 drill with it. Works perfect for me and they are cheap, it starts good and runs strong, turbo'd 404 sounds hearty with 4 and a half inch straight.......... |

Devils Lake, ND | Just like the 5020, they were overbuilt, and heavy. Adding an aftercooler and turning up the pump made it a 4620, and a heck of a tractor, |

Modena, Wisconsin | If you have looked at a 4620 you know what a 4520 looks like. The 46 replaced the 45 with a few changes to the engine mainly. The were rated at 122 hp but could handle more than that pretty easy. They are not as nimble as the 4020 or 4320 but still will out turn the large frame 30 or 40 series tractors. They are about the same hp as the 4320 but have much more beef in them. They can usually be found for less than half of the cost of a 4430 and will do the same work and sometimes more.

Coldwater, Michigan | That set of tires look real good on that tractor.

Oregon | I used to have a '69 model. It was a SR but PS were also made. They were Deere's first turbo ed tractor...and they got it right. They were made in '69 and '70. The latest one's were inter cooled. They had dual single stage air filters with an exhaust aspirated honey-comb pre cleaner that was very effective. According to JR Hobbs, they had air cleaner failures (fires) and they were changed to the 4620 design with a single primary/secondary air filter system. Mine was still the original design and I had no trouble with it. As I said, the pre-cleaner worked really good. Deere developed the 20.8 38 tire for the 4520. I still have an original brochure from when they were new which explains that fact. Mine had between 9000 and 9500 hr on it when I sold it (wish I still had it). The engine was all original (except I rolled a new set of bearings in it at about 7200 hr for good measure...friend had a 4620 which wrecked a crank at the time) and it still started good. The starter bushings were worn which caused it to turn rather slow. You would turn the key and the starter would lumber along turning the engine very slow and she'd always light up and go. I had the starter gone through (didn't realize at the time how bad it needed work) and it was surprising how much faster it spun. The replies that stated they were a lumbering heavyweight like a 5020 are just plain wrong. The 4520 was very agile, not like a 5020 at all. 4520's are physically much larger than a 4020 but relatively speaking they are just as maneuverable. (I have a 4020 also) It was a very comfortable tractor to drive. They were rated at 122 hp. I also had a 4250 at the same time. It was rated at 120 hp. Those two tractors were very similar in pulling performance, weight (I had them both set up with radial 20.8 38 duals, recommended ballast and front/rear weight split) and horsepower-hour/gallon by the Nebraska tests. The 42 could out-work the 45 at times because of having twice the gear selection. The 45 and 42 were equal in maneuverability. The 45 was indeed a heavily designed tractor since it weighed the same without a cab as the 42 did with a cab. There was a 4520 near here vor many years sporting an 8V-71 Detroit conversion and the transmission and rear end lived! Can you tell I miss that tractor? |

Oregon | In a word...no. |

|
Keymar, Maryland | we have a 4020 pwshift but someone out west got the idea of puttin a 4520 motor in it....it sure as hell is a tank tho

Oregon | Gunner, what engine is in that one? It has an inline pump if I'm seeing the picture correctly. |

WC Franklin Co., In. | I had a '69 4520 that had the 4620 engine in it. I didn't notice it taking 40 acres to turn it around, and we had it set for 30" rows. It just seemed like a lumbering giant because of it's extra bulk and sitting higher. There's alot of cast iron in those tractors, especially the front axle. |

|
South Plains of Texas | We had a 69 when I was growing up. It was a good tractor except for the fact it had a crappy old cab on it. I always wished I still had it for a module tractor or jobs like that. The only problem we had with ours was it seemed like the clutch was a little weak for that size of tractor. We had too replace several clutches especially if a hand didn't take care of it. |

NW Ohio | I had a 69 4520 that I added the intercooler to and changed to a high pressure pump with new injectors. It was at about 165 hp and handled great. It was an overgrown 4020 that had a better ride and much better handling than similar size tractors for it's day. Many people didn't like them because of not enough power but as was mentioned they were a heck of a tractor when juiced up a little. |

|
| they did come with power shift |

Blue Grass (Eastern IA) | Most 4520's were upgraded to 4620 engines in the first few years. Think they were a 531 not a 404. There was a major problem with them. Don't remmember what it was, but it was a big deal like the crank shafts on combines a couple of years ago. History repeats. |
|
| |
|
| The only difference was the 4620 had a factory intercooler. The 4520 was known as a "dog" with a bad engine. John Deere had a "recall" on the 4520's where the owner could take it to the JD dealer and deere would install the new turbo and intercooler. (maybe just the intercooler). Other wise the tractors were twins. Both tractors had the 404 cu.in. engine. The 5020, 7520 and 6030 had the 531 cu.in engine.,The latter 2 of these with factory turbo and intercooler. |

Modena, Wisconsin | It is a 466 out of a 4850. It is one 4520 this is not an underpowered dog! The old 404 was not bad but with over 11,000 hours it was tired and this went in for about the same cost as a rebuild. |
|
| |
|
Modena, Wisconsin | Thanks Bill. They are Michelin 650 65 38's. I use it mainly to pull a 12 row 20 inch planter and you can't see a hint of tire tracks behind those. |
|
| |
|
Modena, Wisconsin | There were a couple more differences other than the engine like the 45 had syncros for reverse and the 46 didn't. The main problem with the 45 was the air cleaner system was prone to catching on fire which created the upgrade to a 4620 engine program. The 4620 engine was slightly different than the 45 other than the intercooler and turbo as it did have a different pump which was an improvement also. The "recall" was really an upgrade program where the 4620 engine was installed at "cost". My 45 still had the original engine when I got it but the air cleaner system was the newer 4620 system. |

Saronville NE | Wait till you gotta find parts for the 4520s and 4620s, gettin darn hard to find and used are pricey if can be found. Had a diehard JD guy here with coupld them old girls, he just traded em off cause he couldnt find parts anymore to keep em going, he loved them old girls. They are a good old heavy tractor I always wanted a 4620 just cause I liked the way they look, but after what he told me quess I will just have to look and not own one.

East Central Arkansas | I don't know why you say it took 20 ac to turn around. Must have been something about the way yours was set up. |
|

|
East Central Arkansas | Huh what did you say. I hope you have used ear plugs because I didn't when I had a straight on that old beast. I have two of those old tractors. One I still use for bush hog , boom pole and such. The other one has been parked and got moved out of the tractor shed for lack of room. I really hate that it's out in the weather but that's just the way somethings go when you have as much old junk as I do. |

Modena, Wisconsin | I have had my 45 now for about 6 years and have done plenty of work and have had no problems getting parts. The right side panel where the number goes was out of production for a little while but you could get a 4620 panel for it. The 4520 panel is back in the system again. That was the only thing I have ever had the dealer could not get me. I also have a good salvage yard near me that I have went to because they were much cheaper and new vs used did not make a difference with the part. |

The early 6030's were non-turbo...... Pretty much a re-badged 5020....

East Central Arkansas | What kind of changes did you have to make to bolt that engine in? |
|
| |
|
Modena, Wisconsin | Only real change was to change the bolt pattern on the frame from small pattern to the big one. The old one was cut out and a new plate with the correct hole spacing was welded in. I used a 4620 intake manifold to get an intercooler and the 4520 exhaust manifold. With those manifolds all the holes in the hood matched up perfect. The 4520 water pump was used to keep the fan in the same place to work with the fan shroud. One other small change was I had to go to an electric tach because the engine did not have a manual tach drive. There really was not much modification required to make it work. |

| It was an option on the early 6030's. |
