I bypassed the seat safety switch and ran the mower with the cutter drive engaged so I could watch and LH cutter drive pulley wobbles, so I'll have to strip it down to investigate. No doubt the shaft has bent as it is a very flimsy design.
However, with the cutter drive engaged (and the engine off of course!), I can turn the pulley using a pocket balance, which indicates 3kg of force to turn it.
This seems way to loose and the mower shouldn't have lost adjustment as it's hardly had any use.
