Recommended Fluids and Lubricants, page 113
for quantity.
7. Close endshield(s). See

6.6.10 Knifehead Shield

The shield attaches to the endsheet and reduces the knifehead opening to prevent cut crop from accumulating in
the knifehead cut-out creating plugging.
It is recommended that the shield(s) be installed when harvesting severely lodged crop or any crop condition where
plugging occurs at the knifehead cutout.
The shield(s) and mounting hardware are available from your MacDon Dealer.
Shields should be removed when cutting with the cutterbar on the ground in muddy conditions. Mud
may pack into the cavity behind the shield and cause knife drive box failures.
