CONCAVE
If the grass clippings do not enter the grassbox
satisfactorily, the concave needs adjusting:
1.
Release the two setscrews (Fig. 35) at each
side, which secure the concave to the side
frame.
2.
Move the concave until there is
approxiamately 1.5mm (1/16in) between the
concave and cutting cylinder, measured as
near to the centre line of the cylinder as
possible.
3.
Ensure that the concave aligns correctly
with
the bottom edge of the bottom block
before retightening the setscrew.
NOTE: The concave must not touch the cutting
cylinder.
CHAIN TENSIONERS (FIG. 36 & 36A)
Manual adjustment.
When correctly adjusted, both transmission chains
should be slightly slack in all positions.
1.
Remove the chaincase.
2.
Check the tension of the chain to ensure
that there are no tight spots.
3.
If adjustment is necessary, slacken nut (A)
and push the pinion (B) towards the chain
until the required tension is obtained.
4.
Tighten nut.
If at any time a chain is removed, ensure when
replacing that the gap in the spring clip points
away from the direction of rotation.
Automatic adjustment
Self adjusting Chain Tensioners need No
adjustment (Fig. 36A).
BRAKE (FIG. 37)
IF ADJUSTMENT IS NECESSARY:
1.
Slacken the locknut (A).
2.
Turn the adjusting screw (B) anti-clockwise.
3.
Re-tighten the locknut.
Make certain that after adjusting there is still some
slack movement on the lever to avoid the brake
shoes rubbing against the landroll when the brake
is disengaged.
CLUTCH CONTROLS
The clutch controls have been accurately set.
Should any adjustments be necessary contact
