Hope someone can explain to me the best way to operate this thing. Do I really have to shut the tractor off in order to start it? And what happens if I just need to hop off for a second to move something but don't want to leave it on? but don't want to start the process all over again? Use to 100 series and 8000 series. Thanks ------------- rieg |

The owners manual should explain what a seasonal pto means... Do you have the safety switches adjusted properly that you can't start it? |

Stage coach Handel on the right should start and stop the pto but should stay forward most of the time the seasonal disconnect on the left down is off up is on ------------- You can wash the dirt off the body but you can’t wash the farmer out of the heart and soul |

If switches are adjusted correctly once the pto is started and running can it be stopped by pulling back on the stage coach lever and then restarted without moving the disconnect ? I don't want to put stress on the thrust bearing. Also while using tractor for general chores is the SC lever to remain forward? This tractor is new to me and just being put into service after rebuilding engine this winter. Bought it to be a haying tractor among other choirs. PTO is just strange. Thanks for your help. ------------- rieg |

| It is strange, because it is of European design !!! The general idea is to avoid having the right hand lever (the clutch release) pulled back for long periods of time. This especially true when STARTING the engine cold when there is no oil pressure to the thrust bearing surface. The 6080 was the worst of the three 6000 tractors because it had a bigger/stiffer clutch. |

If you are actually using PTO, don't mess with the left lever. Just use the stagecoach lever on the right just as you would the pto lever on a 100 series. We maybe lucked out, OR there is a bit to much worry, but dad had a early 6080 and sometimes his well meaning-ed boys would forget the disengage lever. Yes it had the front plate installed. Anyway, that tractor is still running today with no issues related to any PTO / transmission.

| That's really nice to have someone contradict good advice from people who know there can be and has been a problem over the years. The price of a crankshaft and block is expensive as is the down time. A bit too much worry ????? There was a high enough failure rate back in the early 1980's that a repair kit had to be created to stop the failures on the 6080 tractor. Not all Customers are created equal. Some log many more hrs per year than others. Out of those, some use the PTO a much higher percentage of the time than others. To basically suggest "don't worry, we never had trouble, do as you like" is just poor advice. |

From my experience, DrAllis has forgot more about AC tractors than most of us will ever know. Listening to his advice has saved me a considerable amount of money and aggravation.

Fiat tractor and an Allis engine. I have my 6060 adjusted so the long Rt hand lever will not lock back. Reduce the engine RPM, pull long lever back, pull up left hand thingy, release rt hand lever slowley. If I need to stop and get off, pull rt hand lever back and push left hand thingy down, release rt hand lever. Works for me. Read the owners manual and listen to the Dr. Bill

My 2010 year 9040 Zetor has the same PTO clutch style. I am not supposed to disengage PTO more than 10 minuets by holding clutch handle up. Tim ------------- 1950 WD 1959 D14 1955 WD45 1976 7000 B 207 |

I’m not a OCD about the seasonal disconnect as some but honestly it only takes a second to push the lever on the left down and a couple to shut the tractor off and pull it up. For the amount of time involved the potential of lesser headaches is worth it. Now if I’m raking one field and the next one is just down the road I just use the stagecoach lever. ------------- 8030 and 8050MFWD, 7580, 3 6080's, 160, 7060, 175, heirloom D17, Deere 8760 |

Very simple, bring tractor to idle. Pull back pto disconnect lever, pull up left hand pto lever to engage pto. Slowly release pto disconnect lever to fully engage pto. To stop pto temporarily pull back on pto disconnect. To completely disengage pto Push down on pto lever. DO NOT RUN tractor with pto disconnect pulled back for long periods of time especially if it does not have the front bearing support cage. This is a known problem, if the procedure is followed it will help you avoid bearing failure. ------------- 1968 B-208, 1976 720 (2 of them)Danco brush hog, single bottom plow,52" snow thrower, belly mower,rear tine tiller, rear blade, front blade, 57"sickle bar,1983 917 hydro, 1968 7hp sno-bee, 1968 190XTD |

Thanks so much for all the help I think I can make it work, I know a little about FIATs as I have had a Fiat 2000 spider for thirty years an it too has its weird ways and engineering. I am going to post the instructions on the windshield for my son-in law and myself. Thanks again for the help. happy haying to all ------------- rieg |

I am very sorry. I didn't mean it like that. I must learn to re-read a few times before posting. During baling season and anything using PTO we never used the disengage lever. I agree with everyone that when not using it for periods of time, like plowing, kick it out. For now I shall continue to read and keep mouth shut. Even if I don't know how to type or talk, our 6080 has done much better.  |
