Can anyone help me with locating the lever (I hope) to change the hammer circuit from twin to single for a Kubota Kx61-2? I would presume its like the -3 and sure there are a few people on here with one...

 

I have bought a flail and want to have a go with it but cant find this lever....

 

I've had some panels up in the floor etc and not sure what I'm looking at / for.... Like I say, hoping for a really obvious lever lol 

 

Even a picture would be awesome

Usually just to the side of the boom, it’s just a wee valve lever.  The Yanmar are under the dead man lever on the floor under a plastic blank though just to be awkward.  
 

Dan I pinky promise I never got out the cab for slab stacking and the broken 1 was already broken.

I'm sure you've probably sorted it by now but on the 61-3 it's under the floor, right near the door. Silver handle, turn it 90° 👍 never used the -2 so not sure if it's the same

Cheers but nope not sorted it yet 😞

 

I've looked all over and would seem that maybe mine is piped up for twin and no lever to go back to single... the plot thickens. 

 

I know nothing about digger hydraulics so it's overwhelming in there 😆

It may be that it's double acting only. It doesn't have to be in single acting to run a flail but it helps keep the oil cooler. Plenty of people run flails on things like a Bobcat E19 which is double acting only. You'd need to chat to the flail mainfacturer regarding motor suitability, but most modern ones are set up to run in either direction with a cross line relief.

 

I'd give your cooling system a good blow out and try it. There should be a warning light for oil overheating too.

Cool 😎  cheers Ruben. 

 

It's a jb equipment flail. Says no need for a case drain.... though worst case scenario I was going to put a tap in the return line to run back to tank.... then came unstuck as couldn't see any easy places to put a return in ffs 🙄 😆 

 

I'm dying to smash back the side of my lane for a bit of play time 😆 just didn't want to bugger owt up

Maybe a stupid question but are you sure it's piped for double acting? If you dead head the actuator in one way and then the other does it strain the engine in both directions? I would have thought it was more likely to be piped single acting only, unless it's a retrofit kit someone has added for a specific use

I think it's double acting.... I only say this as I can open and close my grab and a tree shear.... running a grab rotator on it with a diverter valve at the moment

Oh I just saw the other replies. My flail doesn't run at all when the circuit is set to dual acting, it's a femac. 

 

If you add a return to tank I think the retuning oil wants to go back in to the tank below the oil level. If it sprays through the air I think you'll end up with loads of cavitation and frothy oil coming out the top of the tank

Yeah I see about the air etc... all I can see is a few inlets at the bottom with pipes and jubilee clips on etc would be only place to T back into a return if I was going to.

 

I'm more a tractor man than a digger man 😆
