HOW TO Set Auxiliary Flow Controls on Kubota Mini Excavators 

Glad to help!

kubotas makes all there products so much nicer and so easy to operate and set up what ya need wich kubotas are smart

Definitely! I had my tilt bucket on a kx161 and I had to put orfice reducers in after the quick couplers and while it worked it was too slow. Setting it right with this machine is a piece of cake and the orfice reducers are gone!

Thanks for the comment!

Did you get a -5? I got a u48 and couldn’t figure out how to turn on the second set of hydraulic lines. Got into set up settings and stuff messed up. Think I got it figured out.

Thanks for the comment Kent! Kind of confusing the first couple times but now I can adjust the flow rates pretty easily.

Unfortunately I don't know that. It may be in the manual but I doubt it. I think you're on the right track. I'd start low and then bump it up until the hammer is working like you want it to. If you want to be 100% sure a hydraulic shop can put a flow meter on the aux fittings to check flow and pressure.

You are welcome! It definitely makes a big difference slowing down a tilt bucket for fine control

For constant flow you press the trigger button on the back side of the joystick. There's also a valve you can turn so the return flow goes straight to the tank. Here's the link showing that valve. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Rd382rVsPms.html

Thanks for the comment! Appreciate it!

Yes that's correct. I think that's how I set the rotary cutter. But if not it doesn't really matter cause I also turn the one way valve under the hood so if you press L2 it just goes straight to the tank and won't send to coupler. I have another video on that valve you should check out

@NealORussa I saw it. I have a 40 with the Brush Master 42. Specs say it's bidirectional but I am concerned about the free wheeling of the blades forcing hydro back through the valve body if I don't turn the valve under the cover.

@@cvmikeray2 gotcha. I wouldn't see the need for bi directional use except for blade life. I would run it one way with the valve switched one way like I show until blades get dull. Then swap the hoses on the attachment so it spins the other way and uses other side of blades. Then once both sides are worn down take them off and sharpen and repeat.

There are two ways to run the cutter. One is to hold the rocker switch over. The second is to press the trigger button with your pointer finger one time and that will keep it on continuously. When it's going continuous you can press trigger again to stop it or move the rocker in either direction to stop it.

I've never used the trigger button on the right side. But on my machine with the dual aux hydraulics I use the trigger to run my brush cutter on aux 2 (left joystick). You press the trigger button and it sends fluid continuously until you press it again or toggle the thumb switch. That way you don't have to hold the thumb toggle over the whole time you're brush cutting. Maybe the right trigger does the same thing for aux 1.

@@NealORussa I have an Eterra Flail cutter on my Kubota KX040 and have to use the left hand thumb rocker switch to operate it. The button on the left joystick doesn’t make it run continuously much to my frustration. Also, the valve selector in the engine compartment has to be in the vertical position for it to operate. Any suggestions on how to get that left button to work to allow continuous flow so I don’t have to wear out my thumb? Would switching the lines on the cutter fix this? Any help you can give would be appreciated.

@@dougspencer4485 you should have a trigger button on the joystick you use with your pointer finger when you have a grip on the joystick. If it doesn't make your attachment spin the proper direction you have to swap couplers on your hoses.

@@dougspencer4485 i just read your other comment and it sounds like your couplers on your cutter line hoses need to be swapped. Then you can use the one way flow valve to return fluid directly to the tank. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Rd382rVsPms.html

Hey Dave, my left joystick has a trigger button you press with your pointer finger. That is the off on switch for continuous flow.

@@NealORussa thanks so much. I am having to hold down to run. Release & and shuts down. Got to a set up program set wrong? 🤦‍♂️

@@davedawgs no there's nothing in the programming of the computer screen for that. It's only flow rate. That's odd though your trigger isn't on/off

@@NealORussa switched hoses and it worked!

Unfortunately I don't believe so. I had a kx71-3 and a kx161-3ss. Neither of those screens has this capability to adjust flow rates.

@@NealORussa Thanks for the reply

Thumb needs dual flow to open and close. Things that only need single flow are brush cutters that only spin one way, or a hydraulic breaker hammer, etc.

Hey, I don't have a video on maintenance resets, but I could probably do one. I know there is a maintenance screen in the computer there somewhere.

I'd go full bore and then also change the one way valve to drain the return straight to the tank. I have a video on that too.

Here is the valve video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Rd382rVsPms.html

Thanks.

Not sure where you're located, but check out the Facebook group, "Kawasaki jetmate enthusiasts" there are usually a few for sale in there. Otherwise I might be interested in letting one of mine go. Need garage space.

There isn't a way to switch the flow from one port to the other. You have to change the couplers on the attachment to get the switch to work the way you want it. For instance my tilt bucket when I bought it was backwards. I pushed the rocker to the left and it tilted right. I swapped the male and femal couplers.
