Has anyone had or heard of this problem.
I have a John Deere 737 zero turn with a 23hp Kawasaki motor , It keeps on blowing head gaskets ( right hand side ) :hammerhead:
J D have replace the heads once , replace the motor once and machined the heads once .
And again it has blown ( always around 75-100 hrs ) This is the only problem I have with this machine and with only 700 hrs I would like to find out why the head gaskets on this engine ( 23hp ) fail . I have a JD 717A 19 hp with over 2000 hrs on it and have had no real problems .
