One of the main differences between types of zero turn lawn mowers is the position of the mowing deck. The first models of zero turn mowers feature front-mounted decks with a seating area that was free floating behind and on top of the deck area. One of the benefits of the front-mount deck is that attachments like snow plows are easily attached to the mower. Front-mount mowers also tend to be a bit more stable than mid-mount decks. Mid-mount decks were popularized in the 1980s, and they are the most common models today. Mid-mount decks tend to be smaller and more compact for easier storage in residential capacities, and they are easier to haul for off-site jobs.
Zero turn mowers were first intended for use in commercial applications. The larger commercial mowers were significantly faster than traditional riding or push mowers so drivers could cover large amounts of ground in a short period. Commercial mowers are sometimes marketed as "super duty" mowers, and they include larger mowing decks and heavier counterbalance weights so that landscapers can safely navigate steep inclines or wet grass. Some commercial zero turn mowers are convertible to walk-behind mowers for more precise landscaping on large outdoor renovation projects. Smaller, more compact models of zero turn mowers are now available for residential users. Zero turn mowers intended for residential use tend to feature mid-mount decks or front-mount decks that are foldable for easy storage.
One of the concerns of all riding lawn mowers is their fuel consumption and environmental impact. Most models of zero turn mowers feature combustion engines that are fueled by gasoline, diesel fuel or the more environmentally-friendly propane option. Commercial or industrial models of zero turn mowers that run on compressed natural gas are also available. Compressed natural gas is a cleaner burning fossil fuel than gas or propane, but it is not widely available in residential zero turn mowers as of 2010.
