Abstract

A grass-cutting tractor has an internal combustion engine, an apparatus which changes engine speed, and a generator. The apparatus includes a user-manipulated mechanism having a plurality of operating positions. Two of the operating positions are each identified by different grass-related mnemonics, e.g., NORMAL, HEAVY, MEDIUM, HIGH, REGULAR or TALL, which relate to the height of the grass to be cut and one of the positions corresponds to operation of the generator.
