Disc blades come in different shapes and sizes from Agri Supply ® to handle different types of soil and different types of farm implements. Plain disc harrow blades provide careful control over soil tillage, with the size and concavity of the blades determining how much soil is being inverted. Notched disc blades give an aggressive cutting action for soil penetration and cutting through leftover vegetation. Match your farm disc blades to your agricultural needs, and we can help.

With hundreds of disc blades to choose from, we can match the blades you have used up with replacement disc harrow blades. Get new disc harrow blades and quit wasting time and diesel fuel trying to disc with worn-out blades. Replace notched disc blades before they start looking like plain blades so that you are properly tilling your soil for a better crop yield. We have the farm disc blades in the thickness, size and bolt-hole configurations you are looking for.
