Medium Mixer Knife

The K21187 mixer knife is our most commonly used knife. The knife will fit all Patz® vertical mixer wagons. This knife is used for cutting and mixing livestock rations.

This knife is made of a high carbon steel base material that is milled, heat treated, and tungsten hard-face coated. The K21187 mixer knife would be better than or equal to the OEM knife. This knife is 21.25" long.

The K21187 knife is installed to factory settings, no special tools are required. Use K385021BK mounting hardware for this knife. Backing plate K21431 is also available for this knife. Visually inspect the knife to determine wear, an increase in mixing time is a good indication.

Kooima Ag is one of the very few companies which continuously tests and looks for ways to improve wear and edge retention on our knives. Being the manufacturer and producing these in our Iowa plant, allows us to implement changes and run tests without any delays. Also, having a high density of dairies and feedlots close to our plant allows for year-round testing in a variety of rations.
