I recently got a mulching plug for my 36" Ferris Hydrowalk, but it only seems to stop the clippings from being side-discharged, and leaves a clipping trail even when cutting only an inch or so. I've tried every imaginable combination of gators and high-lifts, including a 4-blade setup, but none has yielded acceptable results. The best combo was gator on the inside, high-lift on the discharge side. <p>Has anyone been able to make this mower mulch? I'd sure appreciate hearing about it. Thanks.
