ABSTRACT:
The invention herein discloses an improved and unique new sprayer implement for spraying crops. The sprayer comprises two wing booms, a left and a right which are controlled independently from one another by hydraulic cylinders. The sprayer is capable of maintaining one wing boom in the transport position while the other main wing boom is extended transversely to the direction of travel in the operating position therefore allowing the operator to spray with one side of the sprayer only. This allows the operator to have access to areas of a field where he would not normally be able to work with a wide sprayer. The sprayer is also equipped with an anti-damage locking system whereby a resilient spring or shear pin is released when either one of the main wing booms strikes an obstacle such as a tree or power pole.
