Replacing Quick Change Blades - MacDon R1 Series Operator's Manual

Replacing Quick Change Blades

If the optional quick change blade kit is installed, replace blades as required.
DANGER
To prevent injury or death from the unexpected start-up or fall of a raised machine, always stop the engine and remove
the key from the ignition before leaving the operator's seat or making adjustments to the machine. If the rotary disc
pull-type is raised, always close the lock-out valves, and place blocks under the rotary disc pull-type. Never work on or
beneath an unsupported rotary disc pull-type.
DANGER
Ensure that all bystanders have cleared the area.
WARNING
Disc blades have two sharp cutting edges that can cause serious injury. Exercise caution and wear gloves when working
with, or near, blades.
WARNING
Firmly hold the blade change tool when changing disc blades. Failing to do so can result in the blade change tool
releasing its spring tension, which can result in injury.
1. Position the rotary disc pull-type at an appropriate height for the task.
2. Shut down the engine, and remove the key from the ignition.
3. If the rotary disc pull-type is raised:
a. Place blocks under each end, or just inside each end, of the cutterbar.
b. Lower the rotary disc pull-type onto the blocks.
c. Shut down the engine, and remove the key from the ignition.
d. Close the lift cylinder lock-out valves. For instructions, refer to
