Knifehead Shield
The knifehead shield attaches to the endsheet and reduces the knifehead opening to prevent cut crop from accumulating
in the knifehead cutout.
IMPORTANT:
Remove the shields when using the cutterbar on the ground in muddy conditions. Mud may pack into the cavity behind the
shield which could result in knife drive box failure.
Installing Knifehead Shield
The knifehead shield is primarily used in rice and fine grasses to keep crop from getting caught in the delivery opening. Not
recommended in all conditions.
DANGER

remove the key, and engage the safety props before going under the header for any reason.
