1. An apparatus for measuring the load supported by a strut of a work vehicle, the strut being disposed in supporting relation to a load carrying portion of the work vehicle, the measuring of said load occurring while the work vehicle is in motion, comprising:

  • means for sensing the internal pressure of said strut and delivering a pressure signal responsive to the magnitude of said internal pressure;

    logic means for receiving said pressure signal, detecting a compression condition of said strut, determining a pressure differential correlative to said compression condition, determining the load supported by said strut as a function of said pressure differential, and delivering a load signal indicative of said load; and

    ,memory means for receiving said load signal and recording said load signal as an indication of the magnitude of the load supported by said strut.
