The suspension on this mower is excellent, and the one touch height adjustment is easier to work than other mowers we tested.

The Lawnhog mower only has an 18 inch cutting area (that’s ~254 square inches). It takes about 15% longer to mow a yard with an 18 inch mower than a 20 inch mower (with ~314 square inches). The assembly is a also a bit complicated and may result in a few skinned knuckles. During testing, the ends of the grass had a slightly ragged appearance, which suggests that the mower’s cutting speed is slightly irregular or that the blade wobbles. Also, the plastic body (which is made from primarily virgin plastic instead of recycled content) felt a bit cheap.

  • A quick note about Extension Cords

    The longer the extension cord you use, the more energy is lost in transmission. Thin cords can also heat up dangerously. When using long extension cords, it’s important to make sure that the wire is thick enough to safely and efficiently conduct electricity. Wire thickness is often referred to as “gauge”. Thicker wires have a low gauge, and thin wires have a high gauge.

    For this mower, it’s important to use an 16 gauge (or thicker) wire for extension cords up to 50 feet. For 51-100 feet, 14 gauge is recommended. For longer extension cords (up to 150 ft), please use a 12 gauge (or thicker) extension cord. Thicker wires are generally more expensive, but they can save substantial amounts of electricity, which saves money in the long run.

    Fresh out of the box, the Lawn Hog Mulching Mower requires a bit of assembly. The electric starter is pre-wired, but the handle bars need to be screwed together and attached to the base of the mower. No tools are needed, but take care not to break the cable while fiddling with the bars.

    There’s an optional side discharge attachment, if you prefer to have your mulch in less finely ground pieces. It’s simple to install – simply lift the side flap and slide the discharge chute into place.
