:biggrin: we have a 5-year-old super Z that we had serviced by the local company we bought from until they moved two years ago. Last year I got a grease gun, took off the deck and sharpened the blades, & changed the oil, and hydraulic oil myself. Everything went fine last year... We use our mower through the winter as well so I really didn't add any gas additives... This summer when we started using it on a regular basis after the first use started missing out for the next couple cuts and losing power, now there's a huge power loss... I had been told by one neighbor he thinks it may be a gas gumming issue, I'm not so sure it's not belts, or something else... Any recommendations from the pros out there? Any quick replies would be greatly appreciated
