Drum Mower driveline protection

[circled]

Hi all. Does anyone running a drum mower for hay use a slip clutch coupler or an overrunning clutch for PTO/tractor protection?
I'm a bit leery using nothing, no hole for a shear pin. I am worried about PTO brake as I understand it takes a drum mower a while
to spin down. Any thoughts or suggestions appreciated. Just assembled and have not used yet.
Thank you!

I had one that came with a clutch so I am no help. I would always have a shear pin or clutch for all pto implements though

Belt drive replaces need for slip clutch. I agree ORC protects pto brake from premature failure.
