    Default Planning for a Hydraulic top link- 18.5" to 30" at longest. 5/8" bore for 40 HP CUT?

    My cat1 toplink is 18.5" at it's smallest and 30" at it's longest.
    I'd like to replace it with a hydraulic toplink.
    Will this one work? It's 18" at smallest with a stroke of 12", so 30" at it's longest, same as my toplink. Is 5/8" rod large enough to handle a 40HP CUT, 6ft BB and bushhog?
    Thanks for the input guys, I only want to do this once if I can help it.

    The pin hole is too small, plus you will probably need something with a rod diameter greater than one inch and most everyone recommends a lock valve.

    I recently purchaced this one:

    Here is one slightly longer:

    CCM has similar units.

    Wow, that website is a pain for those of us who are Hyrdaulic newbies.
    I don't think I want the lock valve. I don't mind making slight adjustments
    occasionally, especially for $75 extra dollars. Can you point me to the
    2X11X1.18 CAT I HYD DA TOP LINK CYL without the lock valve?
    I'm having a hard time finding it. thanks for the help!

    Before I bought my cylinder with the lock valve, I priced others without. Mostly the cylinders were close to the same price or higher (see eBay search "top link cylinder"). I also believe the lock valve adds a layer of safety to the setup.

    Surplus Center does have this:
    https://www.surpluscenter.com/item.a...59-10&catname=

    But the pin holes are are too big (you can buy bushings) and perhaps the whole swivel eyes are too large.

    The Surplus Center searches I use are "top link" or "toplink" or "swivel eye". You get different things with each search, but I think it covers it all.

    You can also buy a regular welded cylinder and cut the ends off and weld on swivel eyes, but the cost will add up on you quick.

    Here is one from another vendor, but its retracted length is longer than I wanted.

    Check this thread if you missed in a search

    http://www.tractorbynet.com/forums/h...-top-link.html

    I got the Dalton one and love it. It does not have a lock valve and for what I use it for it it is not necessary. Depending on your needs, it may be a necessity. The thread addresses some of the issues.

    I have a Dalton top link to. It is a cat 2 for my 5103 JD and doesnt have a lock valve either. Works good for what I use it for. It is more expensive than the surplus center brand. Mine is a Prince cylinder with a 3" bore x 10" stroke..... Bull
