Bobcat 770 Saw Help

[dacker]

Hello everyone I have a friend with a 770 Bobcat that has a homemade Jarraff saw attachment that was built some years back. I am posting pics of it as well as specs on the saw and the machine Hydro flow rate etc.... I have 2 questions.

1. Even though a regulator flow valve (pictured) is installed becuse the saw flow rate is less than the standard flow rate on the machine the saw surges at times like its not getting enough fluid. Other than that it seems to work pretty good. So my forst question is what would you all do to pinpoint the cause of the surging?

2. He is thinking about adding 2 more heads to this set up to have 3 blades working in a line. If he does that what would you all do to get the proper flow rate to the heads?

I appreciate any input you all have in advance..... Dale

Surging like that with a homemade rig makes me think somebody's flow valve is fighting the pump more than it's working with it might be worth finding a hydraulics shop guy who's bored some Saturday and just letting him eyeball the whole setup in person rather than chasing it piece by piece. Three heads in a line is a neat idea though Dale.
