Abstract:

An agricultural implement for automatically taking up plastic sheeting and drip tape onto cylindrical drums. In the preferred embodiment, the device is designed to be mounted onto the back of a tractor or the like by means of a three point hitch. The device includes a frame having a first take-up means for receiving the plastic sheeting, a drive means connected to a first cylindrical drum and powered by the tractor, and a by-pass valve located between the drive means and the tractor for controlling the speed of the first take-up means. The first take-up means includes a spiral roller for preventing the plastic sheeting from bunching up. The present invention also includes a second take-up means for receiving the drip tape onto a second cylindrical drum. The second take-up means is preferably powered off of the first drive means. A control means is located between the second take-up means and the drive means for controlling the speed at which the drip tape roll is rotated.
