An oil filled gauge is recommended. A gauge with a 500 psi capacity may have 10 psi increments, and a gauge with a capacity of 1,000 psi may have 20 psi increments. Summary Hydraulics can be a powerful tool to record the agronomical performance of the farm and provide information related to feeding animals. The construction, configuration, and calibration of the scale are well within the capabilities of most producers. Calibration is a must for different temperatures, apparatus, and age and wear of the cylinder or hydraulic system being used as a scale.
Parts are available through many companies.
The pressure gauge capacity and the hydraulic hose and fittings should all meet standards greater than the maximum pressure of the hydraulic cylinder, the operating pressure of the tractor, or the maximum pressure generated by the weight to be measured.
