What requirement is essential for the two tow points on both sides of an asphalt paver?

The requirement that the two tow points on both sides of an asphalt paver must be level above the ground ensures that the machine operates effectively and maintains stability during the paving process. When the tow points are level, it provides a balanced connection to the towing vehicle, which is essential for the proper distribution of weight and the even application of asphalt. This alignment helps prevent uneven wear on the paver and enables precise control during operation, which is critical for achieving high-quality pavement finishes.

Being level also contributes to the safety of the operation; if one side is higher than the other, it could lead to instability while the paver is in motion, potentially causing accidents or damaging the equipment. In addition, a level tow point helps ensure that asphalt is distributed evenly, which is essential for the durability and performance of the finished pavement.
