My lift arms would not lift high enough to operate some implements satisfactorily so....

This little jewel got an attitude adjustment this morning.

This is a huge difference and should eliminate my lifting problem.

Did you shorten or lengthen it? Is that all it took?

dave is right

there is a speficiation to adjust the feedback rod to

the feedback rod is the turnbuckle in the one picture. It is attached to a valve under the 3ph cover. The valve shuts off the fluid flow once the 3ph rises to a set height, which is adjustable via the feedback rod

if the feedback rod is adjusted so that fluid flow is not shut off at full height bad things can happen.

On most of the standard L series and MX's, they specify I think about an inch of free travel. In other words you pull back the lift lever to it's up stop, at that point you should be able to manually lift the 3ph arms about an inch upward. If not you have to adjust the feedback rod accordingly.

If the valve doesn't shut off you can here it straining
