I wish to eliminate the cylinder on my pulltype BUSH HOG. what isthe proper name of the screw type thing? I cannot find thip part in agricultral catalogs because I cannot recall the propername Thanks to all
 
For our 3 point hitches we called it a top Link. Today, most are threaded with right & left hand threads to allow for adjustment. Longer ago they were two piece with slots and clamp bolts to allow for length adjustment. Both types were called top links. They are available in different lengths.
 
I'd keep the cylinder and put doughnuts on the shaft if it is sagging down this would let you raise it over things and allow you to adjust very easy the height.
 
Ratchet jackets (ratcheting handle in the center of the body) can be gotten with different ends. Clevis ends would be commonly used in place of a hydraulic cylinder on a rotary cutter. Some have swivel ball ends and are advertised as top links. Other ends can be found or made for different uses.

The same is true of the common smooth barrel (rod handle thru a hole in the center of the body) type tractor top links. They can be had with the swivel ball ends or different ends. Ones with clevis ends were factory installed on some pull type rotary cutters, as were some using the swivel ball ends.

Both are types of turnbuckles. The advantage of the ratchet jack type is they are easier to adjust under load with a longer handle and the ratchet action. I would use the ratchet jack type on a rotary cutter or other implement to replace a hydraulic cylinder.

Terminology variations, looks like everyone can be right on this one, depending on which one you are thinking of and what you call them. Either will work, with the "top link" type being less expensive than a ratchet jack.
 
This is a ratchet jack. Notice it has ends on it like a hydraulic cylinder:

This is a toplink. Notice it has ends on it like a 3pt hitch arm:

Pick the style that matches your hydraulic cylinder. Normally that would be the ratchet jack, but cylinders sometimes have ball ends on them.
 
I have a SpeeCo ratchet jack on my pull type brush hog. It works great because i don't need to adjust the height of cut on what I mow. It is flat land and I mow several times a year. Saves me hooking up hydraulic cylinder each time i use it.
 
A top link would NEVER have been able to be put on ANY machinery I had that was setup for a hydrolic cylinder That ball end would never fit as it could not go onto the outside of the arm for the cylinder to hook to. I had 2 of the ratchet jack types and a turnbuckle type that dated to before the ratchet jack type. The ratchet type was easier to use. Turn buckle type was older.
