Has anybody here tried mounting a fluid coupling in the PTO drive line on a WD? Been thinking of ways to reduce shock strain on my brush hogging setup. If so, mounting pics would be helpful. (my cutter has a slip clutch..........looking for belt & suspenders approach)

think your RPM would be to low to get it to transmit any power. old 50's Chrysler products used a fluid coupling (torque converter) as part of std trany drive system. Was self contained with no external pump.

A dry fluid coupling might work.

Try a google search on torque convertor. I recall seeing small convertors on small engines and electric motors, like rides at the fair when I went to them. Last state fair was 30+ years ago.

Lou: I ordered one of those dry couplings. When it arrives, maybe you can come and help me install it.

Coke: I remember those old Dodges/Chryslers. Had not thought of the speed issue though.

It's probably a good thing to just "forget". That'll be easy for me. ha ha

Where i worked before we used magnetic couplings as a coupling. It had a internal steel drum and a external aluminum drum, inside was iron filings. A coil around the drums was a magnetic coil which when energized could lock the drums , when voltage was varied the slippage . Used from 0 to 90 V DC to create lockup or slip. These units were in size from 10 to 200 ft.lb. torquer rating
