Ah, ok, good pix! That sure looks to me to be a slip clutch between the main PTO shaft and the main gearbox input, but I have never seen one quite like that before so I'd better not comment any farther regarding its function or lack thereof! It does look kinda like there might be some parts (springs?) missing that would supply "clamping" force to the clutch friction disk.
Ok, you guys with any Servis Gyro experience, what's up with this clutch?

Or maybe not - I just got the owner's manual from "bosshardradio" open (link wouldn't work for me before) and the "shear pin flanges" shown in Figure 2 in that look a bit different than what you have. So it's possible that someone re-did the flanges/clutch in the past. Someone on here might still have seen something just like this though.....
DUH!! Ok, now that I look a bit more closely at that manual - what you have is the "Torque Limiter" (TL) clutch as depicted way back on page 29 of the manual. There are instructions for adjusting it on that page. This clutch does not use regular coil-type springs like many slip clutches today, but uses a spring-metal disk, or "belleville disk", part E in the manual parts diagram. Maybe all you need to do is to re-tighten the bolt/nuts marked N and P between the flanged yoke assembly and the driveplate (they look loose in your photos). And then tighten the 3 capscrews "M" with the heads pointing toward the back of the bushhog. If that puts some pressure on the belleville spring disk, you should be in business. If it is still too loose, it looks like you'll have to loosen the allen-head setscrews "L", and tighten the whole "pilot plate" (G). Your "Three bolt adjusting nuts" (H) appear to be missing.
