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

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 😆 

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 😆 

[swinny]

That's the old girl anyhow... dragged and stacked some timber to somewhere I could get tractor to earlier this week

[swinny]

These screw splitters for diggers... 2.6t etc

 

What are they like at breaking down 36" diameter timber at say 6' long? Does it help to bore into the wood with a ground saw etc bore in 15" a few bores down the length then crack on with splitter?

 

I've had a few and have some more to come removals where there's not loads of room for timber trailer etc, some restricted access. 

 

Rather than cutting it into 2' chunks and man handling with the digger I wondered about cracking it down and switching back to the grab to remove from site..... 

 

I'm talking gnarly crap too .... big fat sycamore with unions etc...

 Poplar? Is it really chewy and harder work? Conifer etc

 

I suppose it handles different timber differently. 

 

Cheers 🍻

Yes that's right.

 

The other thing is as the flail only rotates one way the  motor drain is normally dumped into the return line, it's reversing motors that need a dedicated drain to tank.

[swinny]

So as a follow up. Turns out my machine is dual acting only. 

 

I bought the jb equipment flail and plumbed it in correctly as the motor only should go one way. No case drain needed. My kubota runs the flail fine. To make sure I don't press the pedal the other way I have a piece of 3 1/2" x 1 1/2" I shove under the pedal at that side lol 😆 😂 

 

I also bought the shear for the digger and it was a mass8ve help on a job not long ago.... horrible blackthorn over a building. Just snip and up and away happy days 😊

For that application I’d ring up rather than cone split any day. 
 

Easier and less mess. 
 

all assuming you o my want to make the timber into small enough bits for the digger to handle.
