BACKLAPPING BACKLAPPING BACKLAPPING BACKLAPPING BACKLAPPING
The keen edges of the spiral cutters can be
maintained by backlapping. With the units in the
lowered position proceed as follows:
1. Smear the edges of the spiral cutters with a
medium grade of carborundum paste.*
2. Ensure that the parking brake is applied.
3. Sit in the driving seat and start the engine.
4. Set the throttle control lever to give
approximately 200 R.P.M. cylinder speed.
5. Set the hydraulic drive lever into the up position
for reverse drive and depress the mow foot
switch, the cutting cylinders will run in reverse.
6. Continue to run for a few minutes then stop the
engine to check and adjust the cutting cylinder
to the bottom blade.
7. If the cylinders require further backlapping,
repeat operations 3,4,5,and 6 until the edges
are completely sharp.
*Obtainable from most motor accessory shops or
garages.
NOTE: Even badly dulled edges are usually
resharpened after 10 minutes treatment.
After backlapping is completed, clean off all traces
of carborundum paste from the bottom blades and
spiral cutters. It is essential that this is done
thoroughly otherwise the cutting cylinders and
bottom blades will quickly lose their effectiveness
when they are rotating normally for grass cutting.
