Does this 2009 CT332 have an engine knock?

[resist0r]

Folks - I am in the market for an older Deere of this generation. This one is a 2009 CT332 with I believe the 5030TW. This unit's diesel engine sounds pretty rough to me. What say you? https://media.sandhills.com/Videos/006/013/591/6013591715/6013591715.mp4
