Adding a hydraulic top link..what size hose?

[DawgDr]

Hi folks, I am going to add a hydraulic top link to my Kubota M6060 and I am not sure what size hose 3/8, 1/2?, fittings, and quick couplers to get for my application? Dealer is no help and local agrisupply has no idea either. Spoke to another hydraulic top link dealer, but a 20 week wait is more than I can stand. Planning to use the Agrisupply inexpensive option.

thanks for any help you have give.

Most standard ag quick couplers are 1/2",
as far as the hoses 3/8" will work fine.https://ph.parker.com/us/en/quick-couplings-hydraulic-up-to-3000-psi-iso-5675

1/4" hose will work also and is more flexible. Very small amount of flow capacity is needed for top&tilt.

Edit: I used 3/8" size quick couplers so they could be plumbed directly into the valve ports. The type of valve you're using and the outside diameter of the quick couplers will determine if this is possible in your application. 1/4" couplers might be even better because of their small size but not sure.

I like using 1/4” for its flexibility and easy routing. Most common though is probably 3/8”, your crazy if you even think about using 1/2”.

1/4 inch hose and 1/2 inch male ISO coupler tips.

Just spoke to another owner and he said he bought a M7060 with a factory hydraulic TL and they used 1/2 hose. Why would you not recommend 1/2?

1/2 is harder to bend, and more expensive,,

If you like to work hard,, and spend money,, use 1/2"

Plus, the flow rate needed for a top link is very small. Many people end up putting flow restricters in their top link to slow down the movement.

My grapple uses 1/4" hoses and I run that full stroke much more than a top link would run. The larger the hose, the wall thickness has to be MUCH thicker too because of the increase of internal surface area. Why would you need 1/2" hoses when people use a 1/16" orifice to slow the TL down?

Cost, flexibility, unnecessary flow characteristics.
