7.11 BACKLAPPING _______________________________________________________

This mower is fitted with the ability 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.
• 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.
