I need a little help here. I been running scag tigers for the last 5 - 6 years and have three now all with the 27 kaw and 60" deck, and have gotten use to them and have found the best blades for every day use is two med lift and one high lift on the discharge side. But I bought a hustler super z with a 28hp efi kohler and 60" deck. I love the speed and reponse of the Z but in thick or wet grass I have to slow down so much the tigers pass the Z up. Is this the deck or are the factory blades junk. What are the best blade set-up for the Z, I know it can't be the factory set. What good is all this speed if you can't use it.
