Ok folks, I just traded for a pretty decent 6080. I have ordered an operators manual for it, just hasn't arrived. I would like for someone to explain the proper way to engage and disengage the PTO. Also any do's and don'ts with the PTO. Thanks

I should be able to help but sadly I have no good answer. I have run a 6080 off and on for 38 years now and have never engaged the P.T.O.!

Someone who knows will be along to explain this I'm sure and we'll both learn.

Great question to ask, if it’s not utilized correctly it will cause issues over time. Very important to make sure it is adjusted correctly once you receive your book. Always have the tractor at idle, pull the pto disconnect lever on your right back until it clicks in the lock position. The yellow pto light will come on on the dash. I always push the clutch pedal in so the tractor is at a full stop. Reach down on your left side of the seat and pull up the pto lever. It will most likely grind as it goes in gear but keep constant pressure as you engage it. I have even got myself in the habit of shutting the engine off to avoid hearing the gear chatter as it engages. Restart the tractor, increase the engine speed and slowly release the pto disconnect lever. Yellow light will go out as you allow the lever to move slowly forward to engage the pto. The pto disconnect is useful while baling hay. When I get to the end of a windrow and have to turn or travel a ways to the next windrow I simply pull the disconnect lever back to shut the baler down temporarily, then when I approach the windrow I slowly release the lever and the baler restarts. NEVER run the tractor for long periods of time with the lever pulled back!! This is were damage over time can happen. With the lever pulled back it puts a lot of pressure on the crankshaft bearing at the front of the engine. Over time it will cause issues. Your 6080 should have a bearing support at the front of the engine at the crank. Keep it greased, it is there to help prevent this issue. Otherwise, you shouldn’t have any issues. Disappointed those series didn’t have hydraulic pto like my 190XT which is a 13 year older tractor than our 6060. Otherwise a very good tractor.

Thanks 720. It does have the crank support bearing. The way you explained it was what another guy told me but he was repeating what someone else said to him. You know how things get twisted around when a story is 2nd hand. I just wanted to make sure I was not doing any harm to the tractor by misuse.

...didn't you forget to stress not starting engine with that disconnect pulled back?

If the tractor has sat and is a cold start. I start with left lever by seat down “ disconnected” and right hand clutch forward. Start drive to what or wherever the pto is needed. Shut off pull left lever up to engage pto and right hand clutch back. Start and use the right hand clutch as needed the rest of the day.
