GRASS CATCHER LOCK ADJUSTMENT IN ORDER TO LET IT WELL FIT WITH THE
IMPELLER OUTLET TUBE
For good results, it is important to have the perfect coupling between the grass catcher and the impeller outlet
tube when the grass catcher is closed.
To this purpose, the machine is provided with different adjustment devices with the following practice.
Put the grass catcher in closed position.
Shorter or lengthen the pistons' stem which let the grass catcher tipping.
As consequence, you can remove the gap between the grass catcher and the horizontal part of the impeller outlet tube.
This operation can be put into practice by unscrewing or screwing the screw set at the bottom of the pistons'
stem. (fig. 37).
Move forwards or backwards the grass catcher in a longitudinal direction in order to remove the gap between the
grass catcher and the vertical part of the impeller outlet tube.
This operation can be put into practice by turning out the bolts, which screw the grass catcher to the frame, by
moving the grass catcher towards the slotted holes and by screwing the bolts. (fig. 38).
At last, adjust the metal and rubber pads in order not to let the grass catcher in closed position swing from right
to leave when working in high speeds and on irregular ground. (fig. 39).
