Abstract
A bale wrap tensioning system includes a spindle that can be operatively coupled to a wrap material supply roll and a rotary hydraulic device that has a rotatable input shaft. The input shaft is coupled to the spindle for rotation with the wrap material supply roll. The bale wrap tensioning system includes a control valve that is operable to control a variable pressure of hydraulic fluid displaced by the rotary hydraulic device. The bale wrap tensioning system includes a controller for adjusting the control valve to alter the variable pressure of the hydraulic fluid displaced by the rotary hydraulic device.
