Claim:
1. A method of weighing a load lifted by a lifting arm of a machine, the method comprising: providing an axle sensor at an axle of the machine configured to sense a force exerted on an axle as a result of lifting the load; providing a further sensor configured to sense an angle or slope of the lifting arm relative to a chassis of the machine; providing a chassis sensor configured to sense an angle of a chassis relative to horizontal; receiving in a processor an axle sensor signal from the axle sensor, said axle sensor signal representing the sensed force exerted on the axle as a result of lifting the load; receiving in the processor a further signal from the further sensor, said further signal representing the angle or slope of the lifting arm relative to the chassis of the machine; receiving in the processor a chassis signal from the chassis sensor, said chassis signal representing the angle of the chassis relative to the horizontal; and calculating in the processor, from the received axle sensor signal, the received further signal, and the received chassis signal, the weight of the load lifted by the lifting arm.
