Knife Kit

This knife kit is used to replace all of the knives and bolts on a John Deere® 772 rotary header. These knives are used to cut silage and other feed.

The knives in this kit are treated with tungsten carbide, giving them a longer wear life. These should be installed with the tungsten carbide facing up.

The knives should be replaced when the teeth start to get rounded instead of holding a strong, sharp point. Typically, when there is a 1/4" or less of tungsten carbide left on the leading edge.
