CONCAVE ADJUSTMENT (Fig. 24)
If the grass clippings do not enter the grass box
satisfactorily, the concave needs adjusting.
1. Ensure that the concave aligns correctly with
the edge of the bottom block.
2. Slacken the screws (C) which secure the
concave to the top deck.
3. Move the concave until there is
approximately 1.5mm (1/16in) between the
concave and the cutting cylinder, measured
as near to the centre point of the cylinder as
possible. Should there be difficulty in
obtaining the adjustments, then reverse the
hinge brackets.
4. Retighten the screws.
As the cutting cylinder gradually wears, it may
eventually be necessary to slightly flatten the concave
to maintain the 1.5mm (1/16in) gap between the
concave and the cylinder and keep the grass delivery
high into the box in wet conditions.
NOTE: The concave must not touch the cutting
cylinder.
LANDROLL SCRAPER (Fig.25)
The Landroll scraper should be taught but not so taught
as to distort the side plates. If the scraper becomes
loose tighten by adjusting the self locking nuts (B) at
each end of the scraper. If all adjustment is used up
replace the scraper.
