Frequently Asked Questions (FAQs)

1. Why does my lawnmower have a side discharge?

Side Discharge Mower Advantages Faster blade speed allows for a cleaner cut when mowing. Allow non-stop operation and faster mowing. Good results cutting tall or wet grass. When cast in the optimal direction, discharged grass clippings are returned to the yard as a natural fertilizer.

2. How do I mow my lawn with a side discharge?

For side-discharging lawnmowers, mow one strip of grass, then switch directions with the mower so that the next strip you mow sprays the grass clippings over the area you just mowed. Mowing in strips is better than mowing in a circle because you'll avoid building up mounds of clippings.

3. Is a rear discharge mower better than a side discharge?

The side discharge mower is more difficult to maneuver in tight places when you use a bag, and it holds fewer clippings. If you have a small lawn and obstacles in the way, you may prefer a rear discharge mower. This will be easier to maneuver through tight spaces.

4. Which is better mulching or side discharge?

Both side-discharge and mulching mowers leave grass blades behind. However, a mulching blade chops up clippings into finer pieces so they decompose faster and don't clump as quickly. Using a side-discharge mower you may need to do your own mulching by running over your grass piles multiple times.
