hydraulic ports on a Kubota L3901

[s219]

Here's what the factory kit looks like. Valves are nicely integrated. Rear outlets a little clunky being where they are, but there really isn't good space down behind in my opinion:

The kit is expensive, but I think it's worth it to get the integration. I paid $1300 for the kit with one standard valve and one float valve. A TnT cylinder (not factory) was another $180, then about $25 for the hoses (got them made to size from discounthydraulichose.com).

I plan on adding a side link at some point.

thanks for the pics
i like the lever location, the outlets , like you say will work but not elegant
thats not the factory rear light is it?
if not where did you tap into the lighting circuit?

That's an LED rear light. The power for the work light circuit is under the left fender. More info on the light install here:

thanks
i think i get the concept
are the ports typically labeled as such?
where in the flow does a cushion valve get put if used?

This is a double relief cushion valve

ok,
do they actually help prevent damage?
I would assume that they need to pass a ton of fluid quickly to do so

Use to stop or minimize surge, shock and overload in hydraulic circuits.

Bypasses to opposite side.

External forces could generate up to 4 times the rated pressure of the cyl or valve, so by the relief valve relieving, you might protect the hyd components.
