A bale wrapping system for wrapping a bale while maintaining independent control over both the sensor and brake assemblies. The bale wrapping system generally includes a support frame to secure a roll of wrapping material to a baler, a brake assembly secured to the support frame, wherein the brake assembly is adapted to brake a rotation of the roll of wrapping material, and a sensor assembly secured to the support frame, wherein the sensor assembly includes a sensor wheel adapted to measure an amount of outputted wrapping material. The brake assembly and the sensor assembly operate independent of each other with respect to the roll of wrapping material and the support frame. The support frame may be retrofitted to an existing baler through a coupler and a bracket extending from an elongated rod connecting opposing sides of the support frame.
