Feathering the moldboard is performed by raising it in what increments?

Feathering the moldboard involves making subtle adjustments to its height in order to achieve a smooth and even grading surface. Raising the moldboard in increments of 1/2" to 1" is considered optimal because it allows for a balance between control and effectiveness in fine-tuning the grade without causing drastic changes to the surface being worked on. This range enables operators to gradually shift the angle at which the blade engages the surface, promoting a smoother transition and better finish.

Smaller increments, like those less than 1/2", may not provide sufficient change to effectively feather the surface, while larger increments could lead to uneven grading and compromised results. Thus, the chosen range helps ensure precision in the grading process.
