Im new here this is my first post, but I frequently visit agtalk. I am just starting out grain farming and Im 17 years old. This seems like a good forum with lots of knowledge It does need some work here and there hence the lower price. Just wondering if they are a good tractor? How much fuel do they use in a day of hard tillage work? Im also wondering about shifting the gears? I will be driving it home 50 miles Also the front steering cylinder leaks and was wondering where the reservoir is? I will bring some extra hydraulic fluid , Im assuming it requires hydraulic transmission fluid?

The steering cylinder is fed from the same sump as the rest of the hydraulics. I'll leave the rest to the experts. I just brought home one myself. I needed a grille, it came as a package deal.   |

| I needed the grille for a 7000. Not too much else between them is common. This is now a "parts for sale" tractor. The first batch of parts shipped out today. |

| The A-C 7040 tractor was just the right size and had all the right features at 135 HP. Ahead of everyone else overall with features and performance and the quietest cab ever known to man. Thee most modern hydraulic system, wet clutch, wet brakes, 20-speed transmission, diff lock, planetary final drives, 540/100 PTO, and on and on. It had the right sized engine for the HP. It should never have been discontinued. The 7020 should have been rated at 115 HP instead of 123 HP and left the 7040 in the line-up at 135 HP. |

Glad to see another young fellow here! I'm 18. If I'm not leaving anyone out, there's now 5? of us here on the site that are under 20! I'll tell you something stupid I did a while back...I was at a consignment auction and there was a decent 7040 there. The auctioneer couldn't get it started because he flooded it on ether, smoked the batteries from cranking too much, and had the fuel shut off!! It brought $250. That's no typo. I wanted to bid, but I didn't have that much money with me, and the auctioneer said everything had to be paid in full before the buyer left the property. I only brought $120, as I had only planned on bidding on one small item. I was so mad that day... Worst part was I didn't learn my lesson! The same tractor sold 2 weeks later for $500. Didn't have the money with me then either.... Now I take more money with me to farm equipment auctions!!!!

| What should a decent 7020 bring on a farm sale. It's advertised as shedded but haven't been started in a while. That may scare some off but being I'm a young man trying to get a start like others on here we can't always afford the ones that are pretty and everything works. |

Creston, You can still bid to your hearts content, then go to a local ATM and pay cash at the end of the day. Nobody is going to "check" your wallet during the bid.

| Hi Nick. It's good to see another Ontario member on this site. Congratulations on your tractor purchase. There are quite a few members from ON. on this Forum. What part of the Province are you farming in? There will be a lot of help available from the Forum members. Perhaps you live close to some members. Good luck with your 7040. Ross. |

I have a 7045 power director. The slightly newer slightly updated version of your 7040. I can understand an unknowing auction crew not starting one. The fuel shut off is "backwards", counter intuitive, pull out and it's "on". I guess I can't give you exact fuel numbers, but it's good for it's size and the work you can get done. Shifting gears, you must be completely stopped to shift gears, but you can "shift" the floor buttons on the go. When you step on the clutch, the floor buttons (the hi and low PD) will automatically shift to low, that's normal. There are those that say with practice and knowledge, you can shift the gears rolling, I don't bother with that, I stop like is recommended. Nice find for $3500. Creston, $250?! OUCH!!! |

Hi Ross, I am located about 20 minutes south of Owen sound near Durham. Tbone95 yeah I figured I would have to stop to shift, I have run other old tractors the same way and sometimes in the top couple gears you can kind of rev match. Is it hard to take of from a stop in high gear?

I have 2 7060 power shift tractors. In the late 1970's, before you youngsters were born  and back when these tractors were built the 7060 PS tested 2nd in overall fuel economy. The Deutz air cooled diesel was 1st. Nick, does your 7040 have 1 fuel tank or 2? The left side tank is standard the right side tank is optional. Is it a red belly or a black belly? I don't know if the 7040 was in production long enough that any had black bellies. The 7000 series started off with the frame, engine, and front axle painted kind of a maroon shade. Later A-C switched to black. The 7000 became the 7010. The 7020 was introduced. The 7030 became the 7040 which became the 7045. The 7050 became the 7060. And the "big guy" was the 7080. My experience with the 7060's is that they are good, dependable tractors. AGCO still supplies parts for them. The engine oil bypass filter is under the hood right in front of the cab. It and the 2 differential filters are bears to change. Take your time and be careful. Do not drop the canister lid for the bypass engine oil filter. Any tiny dent in the lid where the O ring goes will result in a leak. When you crawl under the tractor to change the differential filters (1 on each side) be prepared for a lap full of transmission fluid if you're in the wrong position under the tractor. I'm glad that some young guys are on the forum and starting farming. Any young ladies out there? That would be great, too. Starting with low budget equipment is the smart move. Don't tie up too much money in equipment when you're starting out. Conserve your cash and keep a rainy day fund. Good luck!

Not too bad. You can feel it for sure, give it some throttle first and get the feel of the clutch. There's good power response there, but as you'd think, with a big load it could be a challenge. |

| The cabs are incredibly quiet! You can have it wound up full song working, and could carry on a normal voice conversation with someone if they were there with you. I have just a standard / basic seat, and it kinda sucks. I guess there's a premium one that's better. |

| Hey Dan Hunter, I want to say it has both fuel tanks but maybe it doesnt. It is a red belly but was repainted at some time and its black now. All the filters were supposedly changed. I could seed the new ones but I doubt the one underneath were changed. I figure it will be a work in progress tractor that I can fix up as time and money allow. It should last me awhile now because of the size. Its a big difference for me because I only had a 60 horsepower before. I will be looking for a bigger plow and disc next. |

Hey Dan, some of us are not that young anymore and we are still using, buying and fixing these old tractors and equip just to keep the farm going! |

Congrats on buying an AC tractor. 7040s were maroon belly only. Built from 1974-1977. Serial numbers as follows: 1974: 1001-1302, 1975: 1303-4128, 1976: 4129-6839, 1977: 6840-8250. |

| Howdy Nick! welcome to the forum! you will learn there are no dumb questions on the forum and everone will be will to help with any questions you have! the place you add the oil for the hyd system and steering is behind the cab, upper right corner of the rear end. and don't use just any fluid, should be AC 821 fluid or a fluid that's formulated to match 821. it'll say on the back of the jugs. depending on how bad the leak is, it'll take quite a bit of extra fluid to get you home that 50 miles. I would take at least 5 gallons with. and get the 2-1/2 gallon jugs...they are easier to pour (and use a funnel)! my 7080 developed a leak there to, I could count the drips, and it didn't take long for the oil to leave! when it gets low, it won't steer so be careful in traffic! carry your cell phone! |

| Well I picked it up today. everything went well. The tractor ran good other than the throttle linkage needs adjusting. Im quite happy with it, I will get some pictures to put up here. I will need to upgrade implements over the summer, What sized plow and disc will she pull? It has been rebuilt recently and I my soil is average loam, Defiantly not hard pulling clay. |

| it'll handle a 5 bottom plow easy! and a 19-21 ft tandem disk. don't buy anything bigger cuz that'll just work it harder than it needs to! yes it'll pull bigger, but why up excessive wear on it? don't know if you have hills or not. that is what sizes I pull in our hills. |

hi shameless, I think that would work just perfect. Probably 5 furrow 16s maybe 18s. I only have a 10 foot disc right now but it will have to work for this spring only 40 acres.

| yeah...when I bought my 7010 new, all I had was a 12 foot tandem of dads...was a LOT overkill, but I couldn't afford a bigger one til later! did 400 acres with that disk for 2 years before I got a bigger one! you'll be fine, and you'll take a lot of ribbing from others, but all you have to tell them is they can pay for a bigger disk for you then! they shut up! lol...visit a lot of auctions! |

| Hi Nick. I have been following your progress. Have you been able to get some pictures of the tractor? Looking forward to seeing you post them, and to hear the latest developments with this new-to-you tractor. Probably this great weather has been helpful in testing and hopefully enjoying the tractor. Ross. |

Nice looking tractor! The only thing I'd do is take off that muffler and put a straight pipe on there. The almost 90 degree elbow on that muffler will create a lot of back pressure and slow the turbo down.

| Yeah I'm planning on it. I might leave the muffler and put a straight pipe after the muffler and flapper |
