Hydraulic Flow Restrictor on 3rd Function for Samurai Sickle

[tjaltz]

I purchased a Samurai Sickle Bar Cutter for use on my B3200 (6.7 gpm) and my L6060 (9.4 gpm). I will be using 3/8 hose from the 3rd function quick connectors to the Samurai Cutter. The manufacturer felt that the pressure/flow on the B3200 would be fine for the cutter at a fair RPM to achieved the desired flow of 3.5-5GPM. They felt that the L6060 should be okay at a lower RPM, but if it operates the cutter too fast, I may need to install a flow control valve. They suggest the cutter operate at a speed where the teeth of the sickle cutter are visible, and not moving so fast that they are a blur.

The company provided the attached image for a suggestion on how a flow control valve could be installed. I can identify the pressure side of the 3rd function quick connectors and install the flow control as suggested, but since the 3rd function is a two way toggle switch, would this setup only provide a reduced pressure/flow if I use the side of the 3rd function switch that opens the pressure side? The cutter’s motor is bi-direction, so if I were to open the return side of the 3rd function will that pressure/flow to the cutter”s motor be unrestricted?

Anybody running a Samurai Sickle Bar off an L6060 3rd function, without a flow restrictor? Does it work okay at a lower RPM? The L6060 is rated at 9.4 gpm at 2600 RPM, I was planning on running the tractor at about half that RPM when using the Samurai.

Thanks for any input.

This is prime example of why you want to stagger your 3rd function connections. Same hose gets hooked up every time. And once in cab, same button is pressed to run cutter.

If that was the case, and the opposite button were pressed, I don’t believe anything bad would happen. Cutter wouldn’t work as it would be fed pressure to both sides of motor(T fitting at flow control) pump would dead head and a relief valve would open on tractor.
