Left Hand Universal Knife

The K9846710 Left Hand Universal Knives are designed to fit Claas® Self Propelled Forage Harvesters (SPFH) and are the most commonly used knives for cutting material during harvest. These knives are versatile and can be used for both corn and grass harvesting. They play a crucial role in cutting forage into small pieces for cows' consumption, working in conjunction with the shearbar.

These knives are heat treated and feature a tungsten carbide coating, providing excellent durability and performance. It is recommended to install these knives to factory settings, and new bolts K25152120 should be used when replacing the knives. Do not install the bolts with an impact wrench to avoid damaging the threads.

When to Replace:

• Replace when heavy chips are visible in the knives, as this results in a longer length of cut.
• Also, replace when there is no tungsten carbide left on the knife.

Sharpening Recommendations: Sharpen the knives 10-15 passes per hour during pickup work (e.g., cutting grass or cover crops). For corn silage and earlage, sharpen every 10-15 passes every two hours.

For a 20-knife cylinder, you will need 10 knives, and for a 24-knife cylinder, you will need 12 knives. Optional cylinder wear plates K9871982 are available to protect your cylinder from excessive wear under the knives and will require longer bolts K9871982BK.
