First job mowing with the Allis Chalmers 6080

Eldon (WA) · Aug 8, 2017

I got the air conditioning working on this tractor I bought about 5 years ago. Changed out the wheels and got rid of about 3000# of excess weight. Hogged about 25 acres 20 miles from home today in 96* heat....it passed the test and beat the JD 6100D by almost 2 hours time, used a lot less fuel also.

Nice tractor. Jim

(quoted from post at 20:01:03 08/08/17) Nice tractor. Jim

Thanks, bought it on auctiontime for $3400, 150 miles from me. Figured the AC was shot, only needed charged.

Eldon If you do not like the JDs why keep buying they???? LOL

Does your AC 6080 have the crankshaft trust bearing kit on it??? Neighbor bought an AC 6080 new. While it was under warranty they came out and mounted a bearing on the front of the crankshaft to keep it from moving forward. Some thing about the internal thrust bearings/surfaces not holding up. Seemed like rigged up repair on anew tractor.

As long as I can make good money re-selling the green ones I will buy them LOL! Always someone with a green addiction that can't resist!
This one had the thrust kit on it, measured .005 end play when I bought it so all is good. (I think I scared the JD dealer when I was looking at the tractor by asking all these questions, and that is why it ended up on AT.) The problem stems from the Fiat rear end married to the Allis engine. The two clutch system put pressure on the crankshaft when the pto was not engaged. Cold startups caused excessive wear on the crankshaft thrust bearing. About the only way to fix the problem was the external thrust bearing for the crankshaft.

Less fuel, I can buy that, but 2 hrs. faster???

It was a combination of things. The Allis has a 4" longer wheelbase, so I could go faster and still stay in the seat! I have 11L-15 multirib fronts and 18.4 x 30 rears on the Allis, both have a softer sidewall and cushion the ride better than the 9.5L-15 and 15.5 x 38's I had on the Deere. The Allis has 12 speeds compared to the Deere's 9, just couldn't find the right gear in the Deere. The Deere took two turns of the steering wheel to turn around, Allis one...doesn't seem like much, but caused me to use the reverser on the Deere and do a 3pt turn, which takes time. The Allis I can hit the brake and spin right around. Lastly, the grass was not as heavy as the first cut, so to be fair, this probably saved me some time, even though power did not seem to be a problem. The Deere had plenty of power, can't remember it slowing down in the heavy stuff (no doubt it affected the fuel economy, tho).

Eldon It is kind of funny how things work. Around 2000-2005 I made some real good trades on New JD tractors taking in Allis Chalmers 8000 series and Duetz-Allis tractors. The other JD dealers in the area did not want them for much above scrap price. These where good lower houred tractors. I found that the Allis Chalmers guys really where looking for the AC 8000 tractors with lower hours. I got an AC 8010 and AC 8050 that where supper shape and lowered houred. The phone rang off the wall with guys wanting to buy them.

AGCO really killed themselves in this area. The AC dealerships mostly closed or switched brands. So AC is lightly serviced around here. You have one dealer and then a 100 mile drive to the next that has any knowledge or parts in stock. The MF line is better represented but only in tractors. IF you have a MF combine your not going to find parts in stock anywhere locally. So I will not even look at buying or trading any of the newer AGCO products.

My neighbor had two of those.

The engines failed in both of them with rather low hours.

I remember hearing something about a "Rube Goldberg" fix that was external. Apparently, neither of them had the retrofit.

AC was big here i the 70'sand early 80's, lots of big tractors and combines , but the marriage with Duetz killed that , dead.

On the Fiats its not a problem as long as the PTO lever is used to disengage the PTO not the PTO clutch lever which then puts pressure on the flywheel,not a good idea to leave the
PTO clutch lever disengaged anyway as its then spinning the throw out bearing all the time and will cause that to fail prematurely.

jddrawbar · Aug 9, 2017

Just a guess, the AC cab was quieter.....

stonerock · Aug 9, 2017

2 hrs faster is why less fuel,,,,2 hrs faster on 25 ac? sorry dont belive you

We have a 6070, and it has been a very good tractor for haying. Both on the haybine and also on the v-rake. Has even run the discbine in a
pinch or two, but that does require about all the horsepower it can offer. Like you mentioned, very easy on fuel, and an excellent air conditioning
system. My dad uses it more than anyone, and he has some limiting health issues, but the heated and air conditioned cab make it possible for
him to be out helping even if it is quite hot or cold out. The 12spd transmission offers a great selection of gears for various jobs too.

theres nothing about that old ac thats better than the jd, but if you like the thing use it,

A little heads up on your tractor here , never let the hdy . oil get low and if anything here run it over full as you will seeze up the spiders and pinions in the rear end and it will take a big chunk out of your play money to repair . did one last year for a friend FOR THE SECOND TIME because he let the oil level get low and while making turns them little gears really get spinning and get really hot and they will weld themself to the diff pin so bad that you will not just drive out the pin and replace just the pin and also they have a vary bad habit of shearing off the retainer pin that hols the spider gear pin in and it can come out just enough that it reeks havoc in there . The factory recommends that you WELD the pinion pin to the case .Then when have problems the next time
you can buy a new case .

Jim Phelps · Aug 10, 2017

Disagree, I have ran both and in most cases would take the AC over the JD.
