First tractor, AC 6080

Welcome to the club!!!

I can't answer anything specific on your 6080 but I can supply a link to the AGCO parts book.

http://www.agcopartsbooks.com/PartsBooksN/Viewer/Default.aspx?

Just type in 6080 and you will have access to the part numbers and pictures. If you need parts you can find them with the vendors that support this site at the top of this page under "parts".

Good luck with the 6080 and we always like pictures!!

The PTO lever on the 6080 is actually a two step process.  The large lever on the right side of the cab is the seasonal disconnect.  Pulled back, PTO is off, Forward is on.  The lever on the left of the seat is the engagement lever (lift up to engage, down to disengage).  To operate PTO equipment, here is the sequence. 

Starting position: Right hand lever forward, left hand lever down.

1. Pull right hand lever back.  It should stay in that position. 
2. Pull up on left hand lever. 
3. Gently release right hand lever, and the PTO will turn. 

If you are doing something with the PTO, you can stop PTO motion by pulling back on the right hand lever again. 

When you are done using PTO, the steps are:
1. Pull Right hand lever back to stop PTO.
2. Lower left hand PTO lever to disengage the PTO
3. Release right hand lever back to forward position. 

Pretty simple once you get used to the steps.  The right hand device hits two safety switches.  The tractor should not start with the right hand PTO lever all the way back.
The left hand lever is what actually moves a splined collar over the PTO shaft internally in the rear end. 

Welcome to the forum.  You will get lots of answers here.  

Thanks John, i'll get that brake apart soon and see just where the issues are.  We had unseasonably warm weather up until this past weekend and now temps have dropped.  I don't have any heated garage space so hopefully they will come back up a bit.  

Running with that right hand lever pulled back/ engaged for an extended amount of time is NOT a good idea. I 'm a bit anal but when I engage or disengage the left side pto lever I shut the tractor down.

The one inch of play seems a bit small, but not by much.  I think my lever lifts about 2 inches.  It is not like my 190, which has close to six inches on the lever.  I imagine that the other lever on the left side is the FWA engage/disengage. 

I think the best thing to do would be to try and engage the PTO.  Follow the instructions above, and see if anything happens.  Does the PTO spin in the back? 

Forgot to ask earlier.  What part of Maine are you from?  I spent a lot of time living and exploring Maine.  Especially West Central, and Coastal, but have my share of miles on the interior and northern.

The disconnect lever on the left should work freely when the tractor is off, it is nothing but a gear shift.  The long lever on the right is the PTO clutch, that connects to the clutch shaft, you can see it under the platform on the right.  The shaft could be seized or the clutch may be seized, (not good).  You need to get a shop manual and owners manual.  Both are available on E-Bay.  I would not pound on the gear lever on the left, that should be free.  My PTO clutch is seized engaged so after hooking up PTO equipment,  I shut the tractor off, pull the PTO gear shift, on left, up and then start the tractor with the PTO engaged,  however that is hard on the starter and the teeth on the flywheel.  If your PTO clutch is seized disengaged you are out of luck.  The only fix for the PTO clutch is splitting the tractor and replacing it and while you are there you should do the main clutch too.  It is dual clutch, not a 2 stage clutch.  I am going to send you a PM.  I have been down this road and the guys here were a super help.

Thank you for the advice Vern.  I plan on exhausting all possibilities before splitting it and will give your suggestions a try.

Thanks for chiming in. I hope I don't have to split it and I don't really want to pull the cab off. I will keep you guys updated. Hope to put on a couple hours on it tomorrow between morning hunting and afternoon turkey

Mack i meant that splitting the tractor would be a bigger project because of the cab.  I am assuming the cab would have to come off to split it but i would be happy to find out i'm wrong. 

That's nice to hear, thank you for letting me know.

I would probably get the bracket on the cable and then do the adjustments per the manual first.  Could be all that is needed?

pull up the rubber boot on the cable above where the bracket is missing and do a slow drip of some thin oil, looks kinda rusty. the way i see it wires on the terminals should not matter, they both getting compressed and released at the same time.

I am kinda guessing on this but in your 1st pic, is the top lever supposed to hook to the bottom black and silver lever where the hole is empty? Also the top lever about halfway there is a rusted off piece behind it,is that the pivot rusted into or nothing or nothing to do with it ?
I maybe totally wrong and the two levers are not related?

I'm not sure how it got so bad but i pulled up the floor mats and the floor is almost entirely gone.  The center piece has rusted away in to nothing and the left and right hand panels arent far behind. The PTO cable itself is free but the bracket that holds it is just a ball of rust and paper thin metal.  I'm going to price out replacement floor pieces but if it's expensive i'll have to go another route.

Thanks Bradley, i don't think my safety switch is working because the tractor starts up in neutral and the PTO is spinning.  So my seasonal disconnect must be on, and the PTO clutch is stuck on.  Bill said that the seasonal disconnect is just a gear shift so it should not be stuck in gear, but it is.  I have taken a hammer to it and it will not budge.  Its cold and dark here by 4pm so in the evenings i've only been hitting levers/shafts with acetone/atf mix trying to free stuff up.
