Abstract
A motorized conversion kit for converting manually operated roll tarps includes front and rear arm assemblies and a roll tube extension. The front arm assembly includes a drive assembly that drives an output shaft. The output shaft is removably connectable to the roll tube extension that is connected to a modified roll tube. The connection between the output shaft and the roll tube extension has two distinct modes. The output shaft can be removably connected to the roll tube extension with a clevis pin such that the output shaft and the roll tube extension rotate together or the output shaft can be retained within the roll tube extension by a roll pin residing in a peripheral grove in the output shaft so that the output shaft may rotate independently of the roll tube extension. Methods of installing and using the conversion kit are also disclosed.
