FEL brush cutter

[mnausa]

I have a Kioti RX7320PS (73hp) Hydraulic flow rate is 19.2 gal/min.

I have a 4' brush cutter that I want to convert to hydraulic and mount to my FEL.
I plan on hooking it to the rear remote.

What would be a good hydraulic motor that would work for this application?
1"-3" expected cutting capacity.

Should I mount as a direct drive or with a pulley and belt?

Lack of responses makes me think this may not be a good idea.I don't think you will have enough flow to make this work.A four foot cutter is pretty small for a 73 H.P. tractor.

To figure motor size:
GPM times 231 divided by desired motor RPM = displacement in cubic inches per revolution 19 x 231 = 4389 / 600 = 7 .31 CIR

Larger motor runs slower
Smaller motor runs faster

Also you need at least 3/4 inch hoses to the hydraulic motor and a cushion valve to let the blades spin down when the valve is shut off..

Ours is direct coupled to the gearbox:
