Abstract

A robotic mower includes a chassis, a cutting motor driving at least one cutting blade, and a height adjustment assembly. The cutting motor is mounted on a motor bracket. The motor bracket provides structural support for the cutting motor at an adjustable level relative to the chassis. The height adjustment assembly includes a biasing element, a screw engagement nut, and a height adjustment screw. The screw engagement nut is operably coupled to the motor bracket to enable adjustment of a height of the motor bracket via rotation of the height adjustment screw. The height adjustment screw rotates to translate the screw engagement nut vertically along the height adjustment screw based on an engagement of teeth on the screw engagement nut with threads of the height adjustment screw. The teeth of the screw engagement nut are urged toward the threads of the height adjustment screw via the biasing element.
