Abstract: A compact utility loader compact utility loader comprising a frame, a first track and a second track positioned on either side of the frame, and a pair of loader arms. The loader arms are configured to couple with an attachment via a hitch plate and a hitch pin. The compact utility loader is configured such that as the loader arms are raised and lowered, the hitch pin follows a path approximately defined by a curve f(x)=4.641e0.34x. The value “x” represents a horizontal direction and the function f(x) represents a vertical direction.

Abstract: An arm load control system for a work vehicle including a controller comprising a memory and a processor. The controller is configured to determine whether a lift arm is in a maximum load configuration based on a position of the lift arm relative to a chassis of the work vehicle and output a control signal to a propulsion assembly of the work vehicle indicative of instructions to adjust a tractive effort of the work vehicle based on whether the lift arm is in the maximum load configuration.

Abstract: A controller may receive, from a sensor device, machine velocity data indicating a velocity of a machine controlled by a remote control device. The controller may determine, based on the machine velocity data, a distance to be traveled by the machine until the machine stops traveling after a communication, between the machine and the remote control device, is interrupted. The controller may generate, based on the distance, an overlay to indicate the distance. The controller may provide the overlay, for display, with a video feed of an environment surrounding the machine.
