Help me with Circular Hydraulic Limbsaw

[Wildland_Firefighter]

Plan to get this baby...


Thing is..the owner of the business says tractor needs a minimal 15gpm hydraulics. My tractor has 10gpm.

So I think the only option is a PTO hydraulic pump with a resoviar...but need help figuring out how to get it all together to work. The saw will have hoses but I need hoses from the pump to the resoviar, etc. I also need a hydraulic flow lever to activate the saw and get the saw to run. Looks like I need to get a 3pt resoviar for sure.

Anyone have a good idea how to get this set up to work?

Thanks.

You would need a hydro pump set up to run off your 540 pto at the required flow rate or above, reservoir tank , control valve, relief valve and the hoses not an inexpensive assembly. I would think by the time you got the saw plus everything else you be just shy of $4g.

hopefully less..i hope

pump $350-600, Hose $2-3/ft, tank $200, Relief Valve $60, control valve $100, Hose fittings say $100, Couplings $100 Just a rough idea.

could you recommend me a control valve? looks like some have relief valves in them?

also do i need an inline filter?

A filter should be used for sure, in the return line after your valve. I think that if you can make a bigger tank work, it should be at least as big as the pump's GPM, might be bigger than that with a motor & pump. (vs just a pump & cyl set up) Motors create a lot of heat.
I want to build something similar for trail trimming, keep us up to date with your project.

Got the saw in

That looks pretty cool. Watching the video it looks like it gets put in the dirt a lot though.

What is your main use going to be?

Trimming up fencerows.

lost some acreage of ag fields to overgrowth

probably trim roads in the woods too.
