how to sharpen tractor shredder blades

Tractor shredders are important agricultural equipments used to cut, shred or grind farm waste materials such as weeds, leaves, branches and other debris. Over time, the blades of the shredder become dull and lose their efficiency. Sharpening the blades helps to increase their lifespan and ensures they perform optimally. In this article, we’ll walk you through the process of sharpening tractor shredder blades.

Tools required

To sharpen the blades, you’ll need the following tools: a bench grinder, a file, a wire brush, safety glasses and gloves. Ensure the grinder has a fine grit stone and the file is a double-cut mill file. These tools are easily available at most hardware stores.

Preparing the shredder

Before you begin sharpening the blades, disconnect the shredder from the tractor and remove any debris. Make sure the blades are safe to handle and there are no damaged or broken parts. Inspect the blades to ensure they’re not bent or chipped. If you find any defects, it’s best to replace the blade to avoid any accidents during operation.

Sharpening the blades

Start by securing the blade on a table vise with one end protruding outwards. Tighten the vise firmly to ensure the blade doesn’t move when sharpening. If you don’t have a vise, a clamp will suffice. Put on your safety glasses and gloves to protect yourself from flying debris.Next, sharpen the blade using a bench grinder. Position the blade at a 45-degree angle to the grinder wheel and apply light pressure as you move it back and forth across the wheel. Ensure you maintain the same angle and apply even pressure on both sides of the blade.After grinding, use a double-cut file to sharpen the tips of the blades by ensuring the file’s teeth are facing forward towards the tip. Ensure to file in the direction of the tip to avoid dulling the edge. Repeat the process on the other side of the blade.

Reassembling the shredder

After sharpening, reassemble the shredder and ensure all the nuts and bolts are securely tightened. It’s recommended to grease the blade’s pivot points to reduce friction and prolong the blade’s lifespan. Test the blade’s sharpness by running it for a short period and checking how well it cuts through the debris.

Conclusion

Sharpening your tractor shredder blades is a simple process that can save you both time and money. Regularly sharpening the blades ensures optimal performance, reduces wear and tear, and extends the shredder’s lifespan. Remember to always wear safety gear when handling the blades or operating the shredder.
