Mower, especially for grass at airports

摘要

A mower especially suited for mowing fields at airports has a plurality of blades connected to a rotatable shaft and includes a fixed bed knife arranged parallel to the rotatable shaft and inclined at 20 to 60 degrees relative to a horizontal plane passing through the shaft rotating axis, the bed knife having a toothed profile of a shape complementary to the shape of the outer end portions of the chopping blades with which the toothed profiles are adapted to intermesh during rotation of the chopping blades relative to the fixed bed knife.
