A gas-powered Kubota Zero Turn Mower offers the operator the convenience of having more places to purchase fuel, while the diesel variety uses less fuel and pours fewer emissions into the atmosphere. The choice of fuel does not affect how the machine operates.
The main difference between the Kubota mower options, other than size, is whether the machine is air or water cooled. The latter is available in the larger units that are more suited for commercial operations or home owners with large lots.
Combine a water cooled engine with the diesel fuel option and the mower doesn't heat up as fast and is able to run longer. The water cooled engine also keeps the gas model working longer, but the user usually has to fill up more often.
The zero-turn mower gets it name because it has virtually no turning radius. Instead of a steering wheel, the mower is operated by levers that control the two back wheels individually. The front wheels are unpowered. To turn right, the left lever is pushed forward, causing the left rear wheel to move while the right rear remains stationary. The mower pivots on the stationary wheel.
The zero-mower takes less time to mow a lawn because the gardener isn't left with rows of uncut grass that must be cut in a second pass. A disadvantage is that the mower is not safe for landscapes with slopes greater than 10 to 15 degrees. The pivoting steering system makes it easy for these mowers to roll over.
