A lawn mowing apparatus may include sensors that are fastened to both its mower deck and its chassis. The sensors may sense a position of the mower deck in relation to the chassis. The sensed position of the mower deck may be presented to the operator via a dashboard display of the lawn tractor or transmitted via a wireless signal to another device. Based on such sensed position, an operator of the lawn tractor may manually adjust the position of the mower deck until the sensed position of the mower deck is within an acceptable operating range. In some embodiments, servomotors may used to adjust the position of the mower deck until the sensed position of the mower deck is within an acceptable range.

The present invention provides an autonomous traveling work machine that can accurately receive positioning signals from navigation satellites and autonomously travel without deviating from a traveling path, even in the case of an inclined slope. The autonomous traveling work machine includes a traveling machine body, a positioning receiver that receives positioning signals from navigation satellites, an autonomous traveling control device that performs control for autonomous traveling along traveling paths based on the positioning signals, an inclination detection unit that detects the inclination of the traveling machine body and outputs inclination angle information, an inclination angle determination unit that determines an inclination angle based on the inclination angle information, and a rotation control mechanism that rotates the positioning receiver with one or more degrees of freedom. The rotation control mechanism keeps the positioning receiver horizontal based on the inclination angle.

An electric riding lawn mower includes a seat for a user to ride, a main frame to support the seat, a power output assembly including a mowing element to output power to realize mowing function and a first motor to drive the mowing element, a walking assembly to at least drive the electric riding lawn mower to travel in the direction of a first straight line on the ground and a second motor to drive the walking assembly, and a power supply device to power the electric riding lawn mower with a first battery pack, which includes a first battery pack housing and a plurality of battery cells disposed therein. The power supply device is mounted to the main frame. At least one of the first battery packs of the power supply device forms a pluggable connection with the main frame. The battery cells are lithium batteries.
