Hydraulic control system for a bale wrap feeding assembly of an agricultural harvester

A bale wrap feeding assembly for an agricultural harvester, comprising:

• a hydraulic motor configured to drive a bale wrap toward a bale while being driven to rotate in a forward direction;
• and
• a hydraulic control system, comprising:
• a speed sensor configured to output a sensor signal indicative of a speed of the hydraulic motor;
• a proportional relief valve;
• a control valve having a first position and a second position, wherein the control valve is configured to enable hydraulic fluid to flow from a source to a first side of the hydraulic motor to drive the hydraulic motor to rotate in the forward direction while the control valve is in the first position, and the control valve is configured to enable the hydraulic fluid to flow from a reservoir to the first side of the hydraulic motor and to enable the hydraulic fluid to flow from a second side of the hydraulic motor to the proportional relief valve while the control valve is in the second position;
• and
• a controller communicatively coupled to the speed sensor, the proportional relief valve, and the control valve, wherein the controller comprises a processor and a memory, and the controller is configured to:
• receive the sensor signal indicative of the speed of the hydraulic motor;
• and
• in response to determining the speed of the hydraulic motor is greater than a threshold speed:
• control the control valve to move to the second position;
• and
• control the proportional relief valve to control a pressure of the hydraulic fluid flowing from the second side of the hydraulic motor.

A method for controlling a hydraulic motor of a bale wrap feeding assembly, comprising:

• controlling, via a controller having a processor and a memory, a control valve to move to a first position to enable hydraulic fluid to flow from a source to a first side of the hydraulic motor to drive the hydraulic motor to rotate in a forward direction, wherein the hydraulic motor is configured to drive a bale wrap toward a bale while being driven to rotate in the forward direction;
• receiving, via the controller, a sensor signal indicative of a speed of the hydraulic motor;
• and
• in response to determining the speed of the hydraulic motor is greater than a threshold speed:
• controlling, via the controller, the control valve to move to a second position to enable the hydraulic fluid to flow from a reservoir to the first side of the hydraulic motor and to enable the hydraulic fluid to flow from a second side of the hydraulic motor to a proportional relief valve;
• and
• controlling, via the controller, the proportional relief valve to control a pressure of the hydraulic fluid flowing from the second side of the hydraulic motor.
