Abstract

A lawnmower has a belt-driven horizontally-rotating blade with an offset motor. There are three wheels, the front pair being adjustable in height and the rear one able to pivot about a vertical axis. The blades can be replaced when blunt. ADVANTAGE Improved manoeuvrability, exchangeable blades, and suitable for cutting under trees and shrubbery

Description

Stand der TechnikState of the art

Rasenmäher üblicher Art sind in der Form so ausgebildet, daß der Antriebsmotor mit der Schneidemesserwelle direkt verbunden ist.Lawn mowers of the usual type are designed in the form that the drive motor with the cutter blade shaft directly connected is.
