Grapple saw

[Richard Watts]

So I have a rotator on a log grapple. Attached to a small jcb.

I have fitted a grapple saw, 2 , 6 way hydraulic diverters

so the grab works, the rotator works, the saw (cut master basic) 9.4kw motor 64cm sword works

the ram that pushes the sword down is too quick I have put two restrictor 1mm holes each side still too fast

i have tried a diverter from one side to other with a tap between to divert some of the flow but either doesn’t work or too fast. Does anyone know how to set these up. Thanks

What tonnage are they

Weigh just under  5 tonne, but it doesn’t answer my hydraulic problem

Odd, usual problem is too little flow kit, LPG eddie on here should know. K

This is how I have it plumbed at the moment

What's the return line from the saw .
You really need a free flow return for it.
Out of interest what saw have you fitted and what are you planning to use it for, need to be careful on compliancy at the moment because these are going through a very serious health and safety review at the moment with chain speed and chain shot/risk zones being the major focus.

It’s a cutmaster basic from Germany 

you mean there are rules!
where do I find out about them? Although I would really like a bit of help about getting it working first
