A method for estimating load weights for an implement of a work vehicle, the method comprising: controlling, with one or more computing devices, movement of a boom of the work vehicle such that the boom is moved across a range of angular positions, the implement being coupled to the boom; receiving, with the one or more computing devices, load-related data associated with a load weight for the implement as the boom is moved across the range of angular positions; receiving, with the one or more computing devices, operator-initiated control commands associated with controlling an operation of at least one component of the work vehicle as the boom is moved across the range of angular positions; the method being characterized in that it further comprises: identifying, with the one or more computing devices, an operational period occurring as the boom is moved across the range of angular positions during which a variation in the operator-initialed control commands exceeds a variation threshold, the one or more computing devices receiving a data subset of the load-related data during the operational period; and calculating, with the one or more computing devices, the load weight for the implement based on the load-related data received as the boom is moved across the range of angular positions less the data subset of the load-related data received during the operational period. controlling, with one or more computing devices, movement of a boom of the work vehicle such that the boom is moved across a range of angular positions, the implement being coupled to the boom; receiving, with the one or more computing devices, load-related data associated with a load weight for the implement as the boom is moved across the range of angular positions; receiving, with the one or more computing devices, operator-initiated control commands associated with controlling an operation of at least one component of the work vehicle as the boom is moved across the range of angular positions; the method being characterized in that it further comprises: identifying, with the one or more computing devices, an operational period occurring as the boom is moved across the range of angular positions during which a variation in the operator-initialed control commands exceeds a variation threshold, the one or more computing devices receiving a data subset of the load-related data during the operational period; and calculating, with the one or more computing devices, the load weight for the implement based on the load-related data received as the boom is moved across the range of angular positions less the data subset of the load-related data received during the operational period. identifying, with the one or more computing devices, an operational period occurring as the boom is moved across the range of angular positions during which a variation in the operator-initialed control commands exceeds a variation threshold, the one or more computing devices receiving a data subset of the load-related data during the operational period; and calculating, with the one or more computing devices, the load weight for the implement based on the load-related data received as the boom is moved across the range of angular positions less the data subset of the load-related data received during the operational period.
