In order to remove the blades:
Ensure that the machine is disconnected from the tractor and reach arm hydraulic supply to ensure
that the blades do not move during maintenance.
Place a block of wood between a pair of blades in order to lock the belt drive system and allow you to
remove a blade.

Remove and replace with new blade ensuring the blade is mounted in the correct cutting direction for
the machine build; see Figure 5.12. Blades should be orientated to cut downwards.

the threads and torque to 50Nm (36.9 ft-lb).
Repeat procedure on the other remaining blades, including moving the block of wood if required.
