Mower for grass lawns - has elliptical cutter plate with blade mounted on pivot axis

摘要

The grass mower has a cutter with an elliptical plate (4) on which at least one blade is mounted. This is placed with one end locked between the bottom side of the plate and a clamp plate under the cutter. The inner end of the knife (12) can rotate about a pivot axis (11). The plate is made of metal with a certain elasticity. It can be pushed up with a bar shaped tool to provide space to remove the knife from the pivot without damaging the plate.
