A vehicle includes a sprung mass including a cabin coupled to a chassis, tractive assemblies each including at least one tractive element, springs coupling the tractive elements to the sprung mass, each spring imparting an upward force on the sprung mass, load sensors each configured to provide a signal indicative of the force imparted by one of the springs, and a controller operatively coupled to the load sensors. The controller is configured to determine a weight of the sprung mass using the signals from the load sensors and monitor at least one operational condition of the vehicle. The controller is configured to determine whether or not to disable determination of the weight based on the at least one operational condition.
