We have a Yardman ride-on lawnmower. I asked a local garden machinery place to check the uneven cut and perhaps realign the blades (one blade was catching on the ground). They collected the machine and have come back and told me that the clutch for the cutting deck needs to be replaced, and that this would cost us about 」520 (ie about $590) including labour. There was no hiccup in cutting - once or twice the machine wouldn't start last year (cold battery) but once started, the cutting always started. Does this sound reasonable? It sounds to me as though the mechanic is trying it on and has invented a problem that will be expensive to fix!
