Hook Knife

The K28620 fits on Patz® vertical mixer wagons. It is a large knife at 23 5/8" long and 14 13/16" tall and works well as a discharging knife. This knife is used for cutting and mixing livestock rations.

The K28620 mixer knife is made of high carbon base material that is milled, heat treated, and tungsten hard-faced coated. This knife would be equal to or better than the OEM.

These are installed using factory settings, no special tools are required. Use hardware kit K385021BK to install this knife. Visually inspect the knife to determine wear, an increased 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.
