1. An arm load control system for a work vehicle, comprising:
a controller comprising a memory and a processor, wherein the controller is configured to:
determine whether a lift arm is in a maximum load configuration corresponding to engagement between the lift arm and a chassis of the work vehicle or a mechanical stop coupled to the chassis based on a position of the lift arm relative to the 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.
 
8. A method for controlling a lift arm of a work vehicle, comprising:
receiving, via a controller, a first signal indicative of a position of the lift arm;
determining, via the controller, whether the lift arm is in a maximum load configuration corresponding to engagement between the lift arm and a chassis of the work vehicle or a mechanical stop coupled to the chassis based on the position of the lift arm relative to the chassis; and
outputting, via the controller, a control signal indicative of instructions to adjust a tractive effort of the work vehicle based on the determination.
