A vehicle, such as a lawn mower or garden tractor, includes an engine attached to a frame. The frame includes several wheels including two driven wheels. A first axle shaft is attached to the first driven wheel. A second axle shaft attached to the second driven wheel. The vehicle has a transmission for transmitting power from the engine to the first axle shaft and the second axle shaft for driving the first and second wheels. The transmission includes a differential for accommodating different lengths of travel between said first wheel and said second wheel, such as when the vehicle makes a turn. The differential includes a ring gear supported by the first axle shaft and the second axle shaft. A first planet gear is supported on the first planet shaft. The first planet shaft is attached to the ring gear. Similarly, a second planet gear supported on a second planet shaft. The second planet shaft is also attached to the ring gear.
