6.3.1 To ensure that the correct position for the mower unit has been achieved, both control
wheels (right hand and left hand) should be wound in a clockwise direction so that the
grinding wheel may be placed to contact each end of the reel evenly. If the grinding wheel
touches the bedknife or any part other than the reel, the whole unit must be moved by
adjusting the position of the multifix brackets or roller brackets. The exact position required
will be easily seen by looking along the mainshaft from one end of the machine as the
stone is raised to check that the point of contact is in a suitable position (see Figure 6.3.1.)
Rotate hand wheels anti-clockwise to move grinding wheel away from reel. It is important
that the grinding wheel should clear the highest blade along the full length of the reel
before proceeding.
NOTE If the cutting unit has no front roller fitted so that the multifix brackets are used then, once
the correct position for any particular unit has been finalized a “set up guide” should be
completed and filed for future reference so that the identical multifix brackets positions can
be used for all subsequent applications on the same type of unit.
