(Rocks fist-size or larger must be worked around and then removed from the field no amount of blade adjustment will compensate). Surfaces strewn with relatively small rocks often require that the blade be adjusted by means of a wedge or the snath held so the blade edge is somewhere between A and B. Under most mowing conditions, the blade should move over the ground as pictured in A.ī and C are both “wrong”–although under some conditions a certain amount of deviation from the “ideal” is acceptable or even desirable.įor instance, the lay shown in B is fine for areas of tall vegetation especially if shortness or evenness of the stubble is not an issue. Regardless of regional mowing styles, there is a nearly universal agreement among mowers with respect to the blade’s lay.
