1. An agricultural system, comprising:
a towable agricultural implement configured to be towed by a work vehicle, wherein the towable agricultural implement comprises:
a wing tool bar configured to couple to a tow bar assembly or the work vehicle, wherein the wing tool bar is configured to transition between a deployed configuration and a retracted configuration; and
a plurality of row units attached to the wing tool bar; and
an implement protection system configured to detect an obstruction in a path of the wing tool bar, wherein the implement protection system comprises:
a proximity sensor coupled to the wing tool bar, wherein the proximity sensor is configured to output a proximity signal indicative of presence of the obstruction in the path of the wing tool bar; and
a controller coupled to the proximity sensor, wherein the controller is configured to:
receive the proximity signal;
detect the presence of the obstruction based on the proximity signal;
determine whether the wing tool bar is in the deployed configuration or the retracted configuration;
determine the obstruction is on a side of the towable agricultural implement in response to determining the wing tool bar is in the retracted configuration;
determine the obstruction is in front of or behind the towable agricultural implement in response to determining the wing tool bar is in the deployed configuration; and
output a warning signal in response to detecting the presence of the obstruction, wherein the warning signal is indicative of whether the obstruction is on the side of the towable agricultural implement or the obstruction is in front of or behind the towable agricultural implement.
