I have a few spots on hills on the side of my drive/shop that a light duty brush cutter mounted on the FEL would be nice and make my life a lot easier, rather than using a weed eater with a saw blade. It’s just briars and tall grass but would just be tall grass if I could keep it cut.
I’m looking for an used 4’ rotary or flail.
I have an NX5510 so about 10GPM would be a safe max I “think”. 17.9 is max output but you have steering to account for.
I have 3 rear remotes [(1)self centering/(2) float detent self centering)] but considering a summit hydraulics electric spool and swapping the momentary switch for a constant on. Since I have plenty of spare Carling sized switch locations in the cab. That or “rig” a strap/catch to keep a rear remote on.
I assume I would need a relief/bypass type valve incase the rotary hit something to protect the pump and motor?
Question I have is “If 10gpm is enough how do I size the motor correctly? I am not familiar with hydraulic motors outside of how they work.
I found a 4.95in^3 motor on surplus center. That looks to be about 540 at 10-11 GPM, would 1700inlbs be enough to spin a 4’ rotary?
I know I would need to decide on direct drive or drive the PTO input at 540.
Any helpful info is very welcomed.
I thought I saw a thread on this but I can’t seem to find it.
If there is one post the link and I’ll request this be deleted.
