Title
(EN) BOTTOM BLADE FOR GRASS CUTTING UNIT
(FR) LAME INFERIEURE D'UNE UNITE DE TONDEUSE A GAZON
Abstract
(EN)
A wedge-shaped blade/block assembly for a reel-type grass cutter has a tongue (56) in the blade (50) engaging a groove (68) in the bottom block. Abutments (58, 60, 70, 72) above and below the tongue (56) resist vertical forces on the cutting edge (54). A series of generally horizontal bolts acting through the tongue (56) and groove (68) hold the blade firmly in engagement with the bottom block yet permit ready replacement of the blade when worn.
(FR)
Un ensemble de lame/bloc cunéiforme pour une tondeuse de gazon du type à cylindre est doté d'une languette (56) disposée dans la lame (50) et s'emboîtant dans une rainure (68) dans le bloc inférieur. Des portées (58, 60, 70, 72) situées au-dessus de la languette (56) et au-dessous de celle-ci résistent aux formes verticales appliquées au tranchant (54). Une série de boulons sensiblement horizontaux agissant à travers la languette (56) et la rainure (68) servent à immobiliser la lame sur le bloc inférieur tout en permettant le remplacement de ladite lame lorsqu'elle est usée.
