Mower deck blade spindles

Bought a new Ariens 20HP rider. First time I used it on a new lot that had tall grass and straw. Cut the stuff great with no problems. I inspected the mower deck when I was done and the blade spindles has a lot of twine from the bales of straw wrapped around them. I removed the blades and was able to get most of it off but there was still some wrapped tightly around them. I tried cutting it off with a sharp knife but some still remains. Will this hurt anything?

Thanks in advance for your replies.
