Dealer informed me that Toro has made a recall on the compact z-masters. I know it applies to the 20 hp kohler and I am assuming it applies to all units with the muffler mounted below the engine. They want to install heat shields around the muffler and fuel pump and replace the rubber fuel line with a braided metal one. The mechanic I talked to also mentioned that they might be replacing the muffler or adding a deflector to the existing muffler to direct the exhaust below the engine instead of to the side. He told me not to use the unit until repaired. Just wondering if anyone else heard about this or has had their unit repaired.
