KUBOTA ZD 21 ZERO TURN MOWER

[Larry Landers]

I AM A BASEBALL COACH HERE IN SHELBYVILLE TN, WE HAVE A KUBOTA ZD21 DIESEL MOWER THAT WE HAVE HAD FOR YEARS AND HAS ALL WAYS GIVEN GREAT SERVES. BUT RECENTLY IT WILL RUN GREAT COLD BUT AS IT GETS HOT IT WILL CONTINUE TO LOOSE POWER AND COMPLETLY QUIT RUNNING. I HAVE CHANGED AL FILTERS, THE IGNITION SWITCH, DRAINED THE TANK AND STILL HAVING THE SAME PROBLEM ANY SUGGESTIONS WOULD BE GREATLY APPRECIATED. THANK YOU
