Zero-turn mowers possess three features that help them accomplish the difficult feat of making yard work enjoyable. First is their agility. Instead of a steering wheel, you turn them with a pair of levers that allows the two drive wheels to turn at different rates. This enables the machine to pivot or turn along an arc. You can work the mower slowly over an intricate landscape or you can blast out long straight rows. Next, they’re powerful. It’s not unusual for these to run on a 24-horsepower engine (or larger) or a humongous set of batteries with equally hefty motors. Finally, they’re fast. Under optimal conditions, you may achieve top mowing speeds in the range of 6 to 8 mph. If those sound like attributes that would aid you in your mowing (and you can handle the cost), read on for buying info and our reviews of the best.

How Zero-Turn Mowers Work
A zero-turn riding mower consists of an operator platform, a frame and wheels, an engine (or battery bank), transmissions (or motors), and a pair of control levers commonly known as lap bars. In gas mowers, the engine powers a pulley system. One group of pulleys drives the blades, another group powers a pair of transmissions–one at each rear wheel. When you move the lap bar forward or back, you are directing the transmission to go faster, slower, or even turn the opposite way. When one drive wheel turns clockwise and the other counter clockwise, the mower pivots. When the wheels rotate at different rates, the mower turns in an arc-shaped path. When the lap bars are in the neutral position, the mower stops. Aside from a parking brake, there’s no other braking mechanism. Battery-powered zero-turn mowers work the same way, but have separate motors to drive the rear wheels and one for each blade inside the mower deck.
When it comes to transmission, most mowers have a Hydrogear EZT—a well-known and cost-effective residential-grade transaxle with a reputation for durability.
Some mowers use a deck stamped from one piece of steel, others use a deck fabricated from multiple pieces and welded together. A fabricated deck can be built from thicker steel at a lower cost than it would be able to built otherwise. Once you’re talking about stamping metal as thick as 10 gauge (about 1⁄8 inch thick), the cost of stamping such a deck would push up the mower’s price beyond what most people are willing to pay. The decks in the mowers below range from 42 to 52 inches, a typical size in this class of product. When powered by these engines and the Hydrogear, these mowers will deliver a decent cut quality at their rated top speed of 7 mph. Note, however, that cut quality declines steeply if you maintain that speed in very thick grass or on uneven terrain.
As to the electric mowers, they represent the leading edge of the technology in this category. These are remarkable and expensive mowers powered by large-voltage lithium-ion batteries. If you’re interested in reducing mowing noise and simplifying your maintenance routine by eliminating gas and oil, they’re worth a look.
How We Select and Test
To home in on the most promising contenders, we selected a range of the best residential machines based on our experience testing zero-turn mowers and hours of discussion with dealers, distributors, and manufacturers. We balanced a somewhat-accessible price with features.
Then we test. This involves raising and lowering the deck and adjusting the seat. We look at service point access (the air filter, the spark plug, and the oil filter) and how easy it is to remove the deck. We mow approximately an acre with each mower, considering cut and mulching quality while running uphill, downhill, across washboard, and along sidehills. (On sidehills, we’ll mow surfaces pitched up to approximately 20 degrees; manufacturers generally recommend not going steeper than 10 degrees, but we like to be thorough.) We evaluate power and speed relative to cut quality—that is, will the mower deliver a decent quality of cut mowing at full speed. When mowing in damp conditions, we look at whether the mower’s tires accumulate grass and how effectively it discharges moist clippings. Finally, we test maneuverability (these machines are, generally, very nimble) and how readily they come to a stop when you back off the lap bar control levers.
For any of these mowers that we haven’t already tested (the Husqvarna Z254F, Ego Z6 4204, and Ryobi 48140), we’ll update this review with full impressions once we have them. They deserve inclusion among the best due to their potential and features.
