TLB 48 rear remote lines

[Firemedic]

Hi all,
I have a TLB 48. I am looking to run a post pounder with the tractor. I have front remotes however am looking to run remotes to the back. I am getting mixed information of the ability to utilize the rear backhoe lines to power other implements.
Is this possible? If so, how do I dump the fluid back into the tractor?
I have found that Kubota had two items available however they are no longer in production and I am unable to locate the items. I believe these provided three sets of remotes.
L9443 aux hyd kit, 3 spool
L9444 top-n-tilt kit
Is anyone aware where I may find these items or an aftermarket set up that I could utilize?

Thanks!
Mike

Not at all familiar with the details of the l48 hydraulics so I am guessing a bit.

I assume the post pounder has its own open center valve. If so it should run just fine off the backhoe supply.

Off the top of my head my only concern would be the size of the backhoe return line. Those pounders typically want a pretty good size (1") return. What make and model are you considering?

After a little research on L48 hydraulics I think you can simply remove the hoe and connect the post pounder directly to the backhoe outlets.

It appears there are three backhoe outlets, and two selector levers controlling the outlets.

One selector lever controls the supply circuit that feeds the 3pt. The other selector lever controls the supply circuit that feeds the swing cylinders. The third outlet is a simple tank return.

I assume you want the 3pt to work so that selector lever would be placec in the 3pt position. If I understand things correctly that disables the associated backhoe outlet which is not used.

The other outlet is the swing cylinder pump which presumably you would now use to supply the post pounder. So that lever would remain in the "with backhoe connected" position.

With the selectors in those positions you would then connect the post pounder inlet hose to the swing cylinder outlet and the pounder return line would go to the backhoe return coupler.

Connected in that way the post pounder is being fed by the swing cylinder outlet, return is straight to sump via the backhoe return coupler, and the 3pt can be operated to raise, lower, and transport the post pounder.

Hopefully someone with access to a WSM can confirm or correct my analysis. Or better yet send me a copy of the manual.

I have the WSM , but do not know how to interpret the information there.
Can help,.... if you tell me what to look for.

Look for a hydraulic schematic of the full hydraulic system. Also instructions for removing the hoe.

I think I have it pretty well figured out based on some older threads and some study of the parts diagrams.

Your 3 spool remote valve is an interesting wrinkle. I would be curious which of the two pumps the dealer decided to chain to.

Sorry...... I cannot answer the which pump powers the remotes question, by just looking at it.
The L48 actually has THREE pumps!
I am 1500 miles away from the machine, and will not be there again until May.

I do have a WSM with me here in FL though.
I have 2 WSM,...... for occasions just such as this.
One WSM there, and one WSM here.

I'll find the one here, and see if I can figure the OP issue out.

Read my explanation - seems pretty straight forward.

1. Take the hoe off and install the lift arms.
2. Put the main hydraulic selector in 3pt position
3. Leave the swing selector in the backhoe position.
4. Then use the swing cylinder outlet and tank return coupler to supply the post hole pounder

I don't think Kubota documents that in any manual.

That all makes total sense.
I cannot confirm, because I do hot have a "post hole pounder".
Only the OP does!

3pt post hole pounders are no mystery. They typically have a control valve with IN and OUT ports much like a log splitter. As I said in the first post - the main concern is likely the size of the return line on the tractor. The pounders I am familiar with want it to be at least 3/4" if not larger. Here is a link to a typical implement. So far nothimg but crickets from the OP.

Thank you so much for the information! You have been more helpful than the three dealers I have contacted, added together.

Thanks again

I don't know about the diameter of the return line, because as before, I am not where I can see it.
That said: The L48 TLB puts out 24.9 GPM flow, which would seem to be adequate for a post pounder.

You might want to rrsearch that number. The swing cylinder pump is probably closer to 6 GPM which is more than enough for a post driver. They are low flow devices. The return line is important because when the piston fires the accumulated flow is discharged very rapidly.

I am in error!
My 24.9 hyd flow rate number is incorrect!
The flow rate on the L48 TLB is MORE!
The number listed is 26 GPM!

I have no idea of the specific swing cyl. flow rate.
I have no idea of the return line flow rate.
I do not know if all 3 pumps provide equal flow rates.

Dont expect to see 26 GPM at any hydraulic outlet on that machine.

You are quoting total flow which is split across three circuits.

Start by subtracting PS flow and that number drops to around 18 GPM. That flow is then divided into two hydraulic circuits - impleme pump and swing pump. That split is probaably around 60- 40 leaving you about 10-11 GPM at the loader/main backhoe outlet and 7-8 GPM at the swing cylinder outlet. I am sure you can find the exact numbers in your WSM.
