Bottom Mixer Knife

The K385021 Bottom Mixer Knife will fit all Patz® vertical mixer wagons. This knife is used for cutting and mixing livestock rations.

The K385021 mixer knife is made of a high carbon base material that is milled, heat-treated, and tungsten hard face coated. This knife would be equal to or better than the OEM knife.

Typically, there are 1-2 of this style knife installed on the bottom positions. It will look like it is installed backward, the milled edge is on the opposite side of the K21187 medium knife. Use K385021BK mounting hardware to install this knife. These knives are installed using factory settings, no special tools are required. Visually inspect to determine wear, an increase in mixing time would be 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.
