Cutting Knives:
The Bale Knife cutting arm assembly features hardened knife blades that easily cut through bale wrap. If they become dull
they will need to be sharpened, or if damage to the cutting blade occurs, they will need to be replaced.
Kverneland Tines:
The Bale Knife features Kverneland tines which are heat
treated, resulting in a hardened, tough tine. If breakage
occurs, they will need to be replaced.
Replacing
The bolt-on tines allow for easy replacement of a broken
tine, check to make sure the frame is not cracked or
broken. Gloves should always be used and care be taken
while working around and replacing the tines. Ensure the
cutting arm is up in the storage position.
• With the power unit attached, raise the BK to working
height.
• Remove the M20 taper nut on the tine to be replaced.
• Carefully remove the damaged tine, the shaft is on a
taper, gentle tapping may be required to loosen it from
the frame.
• Insert the new tine, replace the M20 nut, ensure the
nut taper is towards the frame.
• Torque the taper nut to 290 – 325 ft lb ft lbs.
Sharpening
Gloves should always be used when sharpening the
blades and extreme care be taken while working around
the blades.
• Inspect the blades for damage and repair if possible.
• Blades may be sharpened in place on the cutting arm,
or removed for sharpening if so desired.
• A good quality 2nd cut file is the best to resharpen the
blades.
• A grinder should never be used to sharpen the blades,
the heat from grinding destroys the blades temper and
decreases its service life.
Replacing
The bolt-on knives allow for easy replacement of a single
damaged knife. Gloves should always be used and
extreme care be taken while working around and replacing
the blades.
• With the power unit attached, lower the cutting arm to
working height.
• Remove the three 3/8 flat head socket screws with a
7/32” allen wrench.
• Carefully remove the damaged knife blade, and
replace with a new one.
• Torque the screws to 24 ft lbs.
