KX121-3 auxiliary hydraulics

[oldnslow]

My KX121-3 Super Series has a thumb, no front control pod. I am wanting to run a brush mower/ mulcher off the thumb lines and not thru. I was considering doing this by securing the thumb and using those lines. After checking the fitting to replace them with quick disconnect one they are stamped "LLO1". Research says the will not take the pressure. The rubber line and fitting goes all the way back to the control block. Question: is this correct info I was given? Can I replace the supply and return lines that will support this? How or can this support the brush mower sit up?
As in the past, thanks for any info......

Something is not adding up as any thumb lines would need to be pressure rated parts.
Post a picture of what your dealing with.

In the first picture it shows the LL01 fitting. I was told that it was not rated for the PSI required to the bush mower. This line goes to the thumb. I was gong to put a quick disconnect on it, When I ran the mower I would use this to plug into....Thanks for looking

That's an O-ring face seal fitting and it would be rated to the excavators hydraulic system, so there is no way you'll over pressure it.
