CONCAVE ADJUSTMENT
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 (A) which secure the
concave to the top deck.
3.
Move the concave until there is
approximately 1.5mm 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 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.
