thanks grumpy , i didnt realise it adjusted the speed i have been using throttle control for that , as the belt was a little smaller i added the spacer for more adjustment on the clutch ? lever now at least it sits still when i need it too !! hahaha 1st time i used it after insalling the new belt it was allgood , then changed . when i emptied the catcher it wasnt where i left it

lucky it just stopped against some long grass . a little more checking i feel . oh and its a qualcast with a suffolk . cheers Dave
