BACKLAPPING OPERATION
NOTE
The Applicator Brush must be free of grease or oil.
• Apply Grinding Compound to the Reels and allow
two minutes for it to ‘work in’.
• Spray a fine ‘mist’ of water onto the Reels and
allow a further two minutes for it to ‘work in’.
• Apply a second application of Compound, followed
by water ‘mist’.
• Continue this process until the Reels and Bedknife
are sharpened satisfactorily.
IMPORTANT
When carrying out the above procedure, it may be
necessary to adjust the Reels to maintain correct Reel to
Bedknife contact.
When Backlapping is completed, use a pressure washer
to thoroughly clean all Compound from the Reels and
Bedknives. Failure to do so will have a reverse effect, as
the Reels rotate in their normal direction, and the Blades
could be damaged
Remove the Backlapping Unit from the Mower. Connect the
Hydraulic Hoses, to the correct ports in the tractor.
Before using the Mower ensure that all Compound has
been removed from the Reels and Bedknives.

The Backlapping procedure should be done once or twice
each month, depending on the hours of operation, and if
the Reels and Bedknives are not sharpened annually.
If the Reels and Bedknives are sharpened at least once
each year, Backlapping should be done every six weeks.
If any Reels or Bedknives are badly scored it may be
necessary to use a ‘Course Grit Compound’ to obtain a
satisfactory result. Compound is available in 50, 80,120
and 180 Grit, for varying conditions.
NOTE
The 120 Grit is used for average or normal conditions.
Coarser 80 Grit can be used for Reels and Bedknives
that are in poor condition. The 50 and 180 Grit are at the
extreme ends of conditions.
