Yes, that's what it means. Most zero turns are controlled by two levers like in the picture above. Each lever controls the flow of hydraulic fluid going to independent hydraulic motors on each rear wheel. If you push the left lever forward and pull the right lever back, the left wheel moves forward while the right wheel moves in reverse. This will make you spin in place in a clockwise circle. If you push both levers forward equally then you move forward in a straight line. If you move both levers forward and the right lever is pushed further than the left, then you will move forward but curve to the left because the right rear wheel is moving faster than the left rear wheel.
It's a very simple but great idea. The only thing you have to be careful of is actually trying to "turn on a dime". If you come to the end of a row and you stop the left wheel completely and drive the right wheel forward so that it does spin with a zero turn radius, then you will turf your lawn. The grip of the non moving rubber tire (in this case the left) on the grass while it is spinning but stationary will tear out the grass and leave a bare spot.
Scag recommends turning like this:
quote: How can I turn with my zero turn riding mower without tearing the turf? Although zero-turn mowers can turn on a dime (or in very tight circles), it is not the best practice to do so on the grass. Even tight turns have the potential to cause turf damage. The best way we have found to prevent and/or greatly minimize turf damage is to:
•Use 3-point / Y-turns at the end of a mowing row rather than zero-turns to change direction. It is still a fast maneuver and will reduce the potential of turf damage greatly.
1. At end of mowing path, turn toward next mowing path. 2. Reverse while turning slightly in opposite direction to align mower with next mowing row. 3. Proceed into next mowing path.
•On "tight" turns, pay special attention to the inside drive wheel. This wheel will naturally spin slower than the outside drive wheel. It is important to keep the inside wheel turning at all times. If the turn is made to cause the inside wheel to stop turning, this is when turf damage can occur. We have found that by using both of these methods, turf damage is all but a thing of the past. Over a short period of time, it becomes second nature and overall productivity can be increased.
