Took the battery box off the 185 to repair the bottom and something I've never noticed
was a short lever just above the round piece the clutch pedal pivots on,looks like it would hook to the clutch rod but its unhooked.Then looked on my 180 and the lever is tied back.What does that lever do and why would both be unhooked?Have had the 180 over 30 years and never noticed it.

I think it's a pto disconnect, maybe this lever is for a 170, I would think they probably have the same Power Director housing but a 170 has different hook ups

The lever for a mechanical PTO goes behind the battery box. Im guessing the tractor was converted to a hydraulic PTO.

Dr. Allis has spoken about them several times when some ones PTO stops working for no reason. He always says to check and make sure that this lever is rotated as far as it will go clockwise.

most 180 185 were spec built w/o hyd pto . when an order came in for a hyd clutch , many times it was installed along with the different coupler and the mechanical unit was left in just not connected to anything,. units that were built for a hyd pto had a plug put in the shaft shifter hole and no fork or detent is the way I remember it.

I think they all had the shifter fork and arm. It was needed to keep the coupling engaged. The just did not have the lever and linkage.

As far as it will go counter-clockwise while someone is turning the PTO shaft at the rear of the tractor to align the splines. Later model units did not have the external lever or internal fork. They went to a sliding coupler with a snap ring inside of it to keep it in place. This is the design that when you roll the tractor back together after internal Power Director work, the coupler gets bumped and the PTO doesn't work after you get it all back together.

Sorry I meant counter clock wise, I should have re-read what I typed before posting.

I am glad someone else did the coupler thing, thought I was the only one....
