Abstract: A wheelchair safety lock with a safety handle that is positioned such that the user of the wheelchair cannot enter or exit the wheelchair without moving the safety handle out of the way. When the safety handle is moved out of the way, the brake of the wheelchair is engaged against the wheels of the wheelchair. In order to operate the wheelchair, the safety handle is moved back into position after the user is seated. The safety handle extends in front of the user above the users lap when the user. is seated in the wheelchair. Therefore, the user cannot exit the wheelchair unless the safety handle is moved, thereby engaging the brake. Similarly, if the safety handle has been moved such that the brake is disengaged, the user can not enter the wheel chair because the safety handle is blocking the entrance. The safety handle must be moved in order to enter the wheelchair, thereby engaging the brake. The safety handle is also useful for the user to hold when declining a steep incline.

Abstract: Crop severing and gathering structure is pivotally connected to the forward end of a cotton row unit housing adjacent a row receiving area. A cutter severs the lower portion of cotton plants offset from the row receiving area of the row unit. A conveyer includes a pair of opposed belts with gripping features which embrace the lower portions of the stems of the cotton plants and move the severed plants in a generally upright position into the row of standing plants that is entering the row receiving area. The severed cotton plants intertwine with the standing row at the front of the housing as the conveyor moves the plants against one side of the row. The standing row with intertwined plants enters the row receiving area, and tandem picking drums located on the same side of the row as the severing and gathering structure remove cotton from both the standing row and the severed plants.
