Is there a height adjustment for the 3 point on a L3901?
Seems when I got the tractor I had to be careful so the quick hitch wouldn’t hit the marker light housing.
Now it’s not ever close.

Adjustment is called the feedback limkage. The procedure is documented in the WSM.

Before jumping in there verify the control lever is coming full up.

Thanks Dan
The control lever has full travel.
All linkage looks proper and tight.
I do see there is a little play in the roll pin where the control lever attaches to the main shaft and other connections.
I’m thinking a little slop in all the connections preventing full travel of potentiometer.

Or, I have had a few heavy implements on and during road travel things can get bouncing pretty good.
I obviously try to avoid this but makes me wonder if something internal got bent.

I think you need to check the adjustment and measure the position of the rock shaft arms before making any pronouncements.

I’m not going to adjust anything yet.
I’m just learning the system and seeing what could have changed.
Im an industrial mechanic and old farm boy growing up on Wild Rice farm so I have some mechanical ability.
I’m interested it picking up a service manual.
Any good place to get one other then dealer?
