7 OPERATION
• 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.

PROCEDURE
1. Apply an even coat of backlapping compound to the entire length of each blade of the reel.
2. Start the tractor and set the tractor P.T.O. to allow reels to rotate at a slow speed.
3. Slowly adjust the P.T.O. speed until the desired reel rotation speed is attained. It should be slow enough
so that the reel will not throw off the backlapping compound as it spins.
4. Once all the blades on the reel are uniformly sharp, shut off the engine and move the PTO to the off
position.
7. Wash all of the backlapping compound from all of the heads. Once they are thoroughly cleaned and dry,
apply a light film of oil to the cutting edges to help prevent rust.
8. After backlapping, the reel to bedknife adjustment should be made again.
