First, insert the mulch plug in the mower and close the side-discharge port. Then mow as you would normally and make a second pass at a right angle to the first to thoroughly mulch the clippings back into the grass. Or bag your clippings. This works well when the grass is of normal height and the leaves are dry.
No. 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.
To install the mulch plug, lift the discharge chute up. Insert the mulch plug into the deck discharge chute opening by fitting the bolt on the rear side of the mulch plug into the hole in the deck. Pivot the mulch plug into place.
In addition to being compatible with other RYOBI machines, this mower's lithium-ion battery lasts up to 40 minutes on a full charge. If your lawn is well-maintained, this gives you plenty of time to mow your yard before you need to recharge the battery. The mower can house up to two batteries.
