Never hooked up hydraulics, need help

[dfkrug]

If I can generalize for the "standard" L Kubotas..... That is,
the ones that are designated Lxx00. Std Ls that I have
seen and owned had a fairly simple steel block, made by a
3rd party, that attached to the tractor under the seat to
provide series access to the tractor's open center hydraulics.
This was used to provide flow for the loader valve, an aux
valve, a backhoe, or all three. The 3pt was not disabled
using this approach. A decent 1-spool valve w/ pwr beyond
costs less than $100, and the whole setup maybe $200. The
Grand Ls are different in that the ones I have checked out
have 2 hyd pumps, instead of only 1. I don't know if that
trend has continued with the current crop of standard Ls, like
the L3400. Just try steering while raising the loader.

You see, this is one reason you usually see me typing,

Thanks, good to know info.

It's not third party, it's true Kubota. And it's not a simple steel block although a good machinist can make one. In fact, someone here has made one for a Grand L.

Some Kubota B series have a rear aux port for hydraulics and they need a special $65 Kubota adapter to connect to. My B2710 has this for rear aux hydraulics. The rear block on all L series are designed to accept only Kubota stackable valves unless you machine your own adapter block.

The front block adapter on L series should be readily available from Kubota as these adapters are used for loader connections. These adapters however, are not compatible with the rear block.

Thanks for all the help! I think I finally understand it to the point that I am going to order the rear remote kit from the dealer today. So the plan is now to install it and order the log splitter and the top link /forums/images/graemlins/smirk.gif I do love my toys....

The blocks I am talking about only provide access to the
hydraulic circuit and did not include any connection for
valves. One I have seen was made by Gearmore and sold
by the Kubota dealer. The Kubota factory-built blocks that are
installed on the right side below the seat have included the
integrated valves. The latter setup is what Kubota charges so
much for. This setup is the one that is NOT an option for the
Lxx00 std Ls I have seen.
