They are not as operator friendly as the full size backhoes, Try sharing pressures by applying light or little movement on each control levers at the same time when operating it. This video I made shows a little simultaneous movement but not much.

It can be done but when functions are run off the same pump (the L48 has three) then one function draws hydraulic power from the other.
This is not so much a problem when flailing around in the air, but when engaged in heavy soil or clay it becomes more apparent. Using one function at a time will show the maximum power available.
The L48 is a nice piece of useful equipment but is nether an excavator nor a full-sized commercial backhoe.

L48 has 2 pumps regarding the BH operation. One is for the swing only, the other is for all of the other functions including the FEL. The PS pump has nothing to do with the hydros.

Well then it is just a matter of re pluming it at the valve. Right?

I wouldn't change the set up since you need the swing to function separate of the other hoe functions. You need to be able to raise the hoe and still have swing to get across a ditch.
fdnyski45, most of the smaller backhoes are set up this way I recommend you grit your teeth and get used to it.

You clearly stated it has 3 pumps and inferred that some how it shares functions between the pumps. The point it has 3 pumps is as moot as mentioning it has 4 wheels and runs on diesel. It actually has 8 pumps on it (4 of which touch hydraulic fluid), but that's just as moot when mentioning backhoe hydraulics. The concern is that the hydraulics use 1 pump, and the swing function of the BH has a dedicated pump. There's no point in clouding an issue with useless information that has no relevancy to the man's question. The other 2 hydraulic pumps have nothing that can be utilized to drive the backhoe.
It probably could be done, but that's a rather expensive piece of equipment to be experimenting on! I'd look at adding a PTO pump for increased flow and pipe it in to feed the valve towards the end. Increasing the flow by 4-5 GPM would do the trick, if the valve could handle it. Way too many factors to consider for someone who doesn't own one. Backhoes usually have flow restrictors on them and being able to feed the valve as 2 separate valves with an equal flow divider in front may yield good results. I'm surprised kubota didn't just add a few more parts in there to increase its usefulness.

You know, if you can't afford your meds the government or the manufacturer can help. But you still have to remember to take them.
Oh, and you inferred. I would have implied if that had been the case. You created the argument out of thin air. Some folks call this a "straw man" argument.
I'm done. Have fun.
It has 4 hydro pumps. So you were just flat wrong all the way around. I take it from you bringing in an issue about meds from the government that you're having trouble with yours? You should have that looked into. Can't help you with that here.
You had inferred that 3 pumps matter and were therefore implying they mattered. You would first have to infer, before you can imply. Had you not inferred they mattered, and then implied it, we wouldn't be having this discussion.
