BACKLAPPING

This mower is fitted with a device to allow the reels
to be driven in reverse for backlapping.
• Backlapping is a process which will lightly
grind the reel to the bedknife whilst
mounted on the mower.
• If significant amounts of metal are to be
removed then the cutting unit should be
reground on a specialised grinding
machine.
• Before any backlapping is carried out,
Ransomes Jacobsen recommends that
the backlapping process should be risk
assessed as a workshop process by the
manager of the machine.
• Backlapping should only be carried out by
trained staff.
• Ransomes Jacobsen recommend that
grinding paste is only applied to the reel
when it is stationery, the engine is off and
the parking brake applied.
• When applying grinding paste the reel
should only be rotated by appropriately
sized piece of wood and not by hand.
• Place reels in the most accessible
position for applying the paste.
• Leave the grass boxes in position on the
cutting units as a safety barrier.
• After applying the grinding paste the
person backlapping should return to the
seat, engage the relevant controls and run
the reels in reverse.
• When the desired finish is achieved switch
off the mower, clean off any surplus paste,
reset the reel to bedknife and return the
controls to the normal mow positions.
