Terry' I have an exmark metro hp 36". I use this mower on my gated properties for leaf clean-up. I use an accelerator catcher for this purpose. I am having some problem with blowout when running excaliber high-lifts,even worse with gators. What blade combination should I use for this purpose and is the deck rake as it was set by the dealer i.e. thick washer in front, thin washer in rear, correct or can I adjust the deck rake to reduce blowout?
