Feeding brush into chippers from the upper tip quadrant is the correct choice because it ensures that the material is fed into the cutting chamber in a manner that promotes efficient and safe processing. When brush is introduced from this area, it helps to direct the limbs and branches downward toward the blades, which can improve the chipping action and reduce the likelihood of jams.

Additionally, when workers feed material from the upper tip quadrant, it minimizes the risk of reaching into the machine and helps ensure that limbs are pulled into the chipper rather than pushed, which can be safer. This positioning also harnesses the natural dynamics of the chipper's design, allowing for better control and more effective cutting.

This practice is rooted in safety guidelines and operational procedures, emphasizing the importance of worker safety and equipment efficiency. In contrast, feeding from the side or the bottom can lead to operational inefficiencies and increase the risk of injury, making the upper tip quadrant the most advantageous approach.
