Abstract

A gear assembly with two inputs and two outputs which can be used on zero turn riding mowers or similar vehicles. The first input is a propelling input and the second input is a steering input. The assembly contains a planet carrier, a first planetary gear assembly, and a second planetary gear assembly. The propelling input is engaged with the planet carrier. The first and second planetary gear assemblies contain a ring gear. The steering input is engaged with the ring gears. The steering input is either a helical bevel gear, straight bevel gear, or a gear train. In another version, the gear assembly can have two planet carriers connected externally to the planetary gear assemblies. In this instance, a central gear is used in between the first planetary gear assembly and the second planetary gear assembly to connect the sun gears.
