A lawn mower or other vehicle having a pitch sensor for sensing a pitch condition of the lawn mower with respect to a horizontal level plane and generating a pitch signal corresponding to the pitch condition. The vehicle includes drive wheels, and has a front-mounted mower or other attachment at least partially supported by attachment wheels. The vehicle also includes a weight transfer assembly, and a controller that receives the pitch signal from the pitch sensor and automatically actuates the weight transfer assembly to adjust the portion of the attachment weight borne by the drive wheels and attachment wheels. Operation of the pitch sensor and controller may be overridden by an operator through a weight transfer switch or dial in the operator zone of the vehicle.
