First time out with this topper since buying it last autumn,I’d changed the wheels then bushed them,also an oil change yet forgot the drive belt,so after checking the tension off to go for 20 minutes,then smoke,severe,stopped,the belt was broken,lifted the engine off and it’s cracked all over and hard,then I noticed the driven pulley,blade one had major rust,so ran the 3” wire brush around it ,should help it’s lifespan,quick search but I failed to find a replacement of the correct size,anyway should be good to go thistle and nettle cutting in the week,as despite the drought they’re getting out of control.
