L2550 3pt hitch modifications

[BruceM]

I need to replace the existing hydraulic top link as it is a frig from a cement mixer; it's a clevis type that is too long for the Countyline 6 foot blade and 5 foot drag box.

I need some advice on suitable top link cylinders. Some special ones claiming to have check valves to stop cylinder movement when not commanded are available. Agrisupply has cylinders with a special check valve for top links:

My question: is this an important feature or is a standard double 3/4" tube type cylinder at half the price adequate for the job?

The same question applies to a hydraulic side lift; they have special ones, but will a standard clevis cylinder work adequately?

Alternately, do you have any advice regarding hydraulic vs one of the hand crank side levers such as this (first item on page):

I don't enjoy using the existing manual screw leveler, and the range of adjustment is such that without a hassle moving the fixed opposing lifter, I can only tilt the right side up.

Private dirt road maintenance is the major activity for this machine.

Hi, I also have the L2550 D that I use to maintain our road all seasons. What did you end up doing for the hitch? If you used hydraulics what source of power did you use? We should compare notes sometime.

I originally used power beyond ports and a separate control valve, but now I am changing to a selector valve fed by the main control valve (bucket tilt) so I can use the main control valve for both functions. I had the engine rebuilt so a blown engine won't end the L2550 life. Presently I am having an issue with 3 pt lift it wants to jump up and down. Anything like that your tractor history?
What mods have you made and what implements do you use?

When you eliminated the Power beyond did you turn everything back to the way it was stock, because there is probably a correlation to why your three point is jumping around.
