The chopper knife on a Wolf Harvester is one of the hardest working parts on your machine. An aggressive rotation is required to chop the incoming hop bine and string into rough mulch about an inch in length. Over time, the rigid edges of the blade become rounded and no longer properly chop the hop bine and string material.
A full replacement requires two knives. Listed prices are for a single chopper knife.
S2S carries the most common lengths: 400 mm and 600 mm.
