Installing Accelerators

A new pair of accelerators should be installed on a cutterbar disc whenever the old ones are damaged or worn to the
extent that they can no longer effectively move crop off the disc and into the conditioner.
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.
IMPORTANT:
Always replace accelerators in pairs to ensure that the discs remain balanced.
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.
