Choose the right size mower/engine, balancing your primary grass mowing need with other anticipated purposes. Know where you will store it when it is not in use. A variety of mowing decks and blade(s) may match your needs, as well. Mowing decks come in different widths--the model in the video has a 42-inch wide deck with dual blades that cut a wide swath and require fewer passes to finish cutting the grass when your yard is large. (Yards that are the size of a postage stamp don't require such a mowing beast.) A tight turning radius allows for close U-turns and makes it easy to trim next to structures, garden beds or edging. Consider how far the mowing deck extends beyond the wheelbase, too--you may want to mow under fences while keeping the tractor housing away from the wire or along flower beds while keeping the wheels on firm ground away from tender plants. Your mower will typically come with a cutting blade, but additional blades offer some options, coming in cutting, thatching, mulching, high-lift, low-lift and varieties that are worth investigating. These blades can be sharpened by a reputable dealer when they lose their edge.
