I would say it stops the engine if seized, bearing in yellow. red static hub with cable return springs

Actually no research needed John , Ive serviced and repaired a fleet of Hrh536 since around 1999 and have a couple myself but memory aint what it once was.You may well be right

Edit: mind you, theres nothing to say that its the cause of the lock up but cheaper than a new engine if it is.

I’ve done a few, but apart from the bearing I can’t recall ever needing new parts in there.
Lets see if we get a post back.

Clearer now its light and stripped further?Yes, I can see how that would cause locking up although it's never happened to me.

I only see this machine a couple of times a week. I removed the recoil unit and the spark plug and was able to rotate the engine with a spanner on the crankshaft nut. No sign of metal filings in the oil. reassembled and the motor started but after a few seconds ground to a halt again. This time I noticed that the rear roller wouldn't turn, so could it possibly be the clutch and final drive that is the problem. (I should have said this is the QX model with a roller instead of wheels at the back).
Presumably this machine has a belt drive to the transmission, rather than the shaft type?
If so, take the belt off and try again......although I think it's unlikely that a belt drive would actually stall the engine - more often they burn.

I believe this is a shaft-drive. It has a strange clutch. After pushing up the drive lever you have to push the machine forward before it will engage and power the roller. So with the drive lever down the roller should be free whether or not the engine is running. I can't see how you get in to the clutch mechanism to investigate.
Your doing it the wrong way and a way that damages the clutch.
The clutch is a dog clutch inside the gearbox so you should be pushing the mower forward as you engage the clutch lever.
