Removing A Blade Pan From A Bush Hog: A Step-By-Step Guide

Removing the blade pan from a bush hog is a challenging task. The blade is attached to a round plate with a smooth head and a nut on top, which is connected to the shaft extending from the gearbox. To remove the blade pan, one must keep the entire setup stable while attempting to loosen the nut. This process can be cumbersome and requires careful rigging to ensure safety. There are various methods to approach this, such as hoisting and securing the bush hog on its side or flipping it over to access the blade carrier pan.

Use a grinder to sharpen the blades in place

Using a grinder to sharpen the blades of a bush hog in place is a feasible option, although it is important to exercise caution as the blades will be sharp enough to grind hands. This method is also challenging because the bush hog will try to move while you are sharpening it.

To sharpen the blades of a bush hog in place, you will need to block the hog up to ensure it does not drop. Most people lay the bush hog on its side and chain it to a tree or similar object. You can then use an angle grinder to sharpen the blades. It is important to note that you should not shape the blade or grind the bottom. Instead, you should focus on removing material from the cutting edge, maintaining the same bevel that exists. You only want to touch the blade with your grinder on the cutting edge.

It is also important to maintain balance by ensuring that the same amount of material is removed from each blade. This will keep the unit in balance. Additionally, you do not want a razor-sharp edge on a bush hog blade, especially if you cut saplings and brush. A very sharp blade can create a spike that could pierce a tire or foot. Instead, you want a pretty steep angle that will tear what you are cutting, but still do so easily.

When sharpening the blades of a bush hog in place, it is crucial to prioritize safety. This includes wearing protective gear, such as heavy-duty work gloves and goggles, and ensuring that the bush hog is securely blocked up to prevent it from dropping.

Lay the hog on its side and chain it to a tree

To remove a blade pan from a bush hog, it is recommended to lay the hog on its side and chain it to a tree. This will ensure the hog is stable and secure while you work.

To do this, first identify a suitable tree that is strong enough to support the weight of the hog and close enough to allow the hog to be laid on its side next to it. Once you have selected the tree, you will need a chain that is long enough to wrap around both the hog and the tree. A standard chain with links should be suitable for this purpose.

Next, lay the hog on its side next to the tree. You may need assistance with this step as hogs can be heavy and awkward to manoeuvre. Ensure that the hog is positioned in a stable manner and will not roll or shift once you begin the removal process.

Once the hog is securely on its side, use the chain to securely fasten the hog to the tree. Wrap the chain around both the hog and the tree, and then attach the ends of the chain together with a sturdy lock or fastener. Ensure that the chain is tight and that the hog cannot shift or move once it has been chained.

With the hog securely chained to the tree, you can now begin the process of removing the blade pan. This will involve removing the bolts that attach the blade pan to the hog. This can be a challenging process, and you may need to use an impact wrench or grinder to remove the bolts if they are seized or difficult to access.

By laying the hog on its side and chaining it to a tree, you create a stable and secure work environment that will make the blade pan removal process safer and more manageable.

Use a 4 electric hand grinder

Using a 4-inch electric hand grinder to remove a blade pan from a bush hog is a challenging but doable task. Here is a step-by-step guide on how to do it:

First, you need to stabilise the bush hog and ensure it is secure. This is crucial for your safety. You can do this by chaining the hog to a tree and laying it on its side. Make sure to use a loader to hoist and secure it safely. It is recommended to have another person assist you with this process.

Once the bush hog is securely on its side, you can access the blade pan. The blade pan is attached to the shaft coming out of the gearbox. You will need to remove the cotter pin, castellated shaft nut, and any other fasteners that hold the blade pan in place. Use the appropriate tools, such as a wrench, to loosen and remove these fasteners.

With the fasteners removed, you can now use the 4-inch electric hand grinder to carefully grind away any remaining attachments or obstructions that are holding the blade pan in place. Always wear the appropriate safety gear, including eye protection and heavy-duty work gloves, when using the grinder.

After you have completely separated the blade pan from the bush hog, remember to lower the machine carefully. It is important to ensure that the blade pan is removed without causing any damage to the surrounding components.

Finally, you can now inspect the blade pan and the bush hog. If necessary, use the grinder to smooth out any rough edges or imperfections on the blade pan. This process will help ensure that the blade pan can be reattached securely and function optimally.

Remember to exercise caution throughout the entire process, as working with heavy machinery and power tools can be dangerous if not handled properly.

Hoist and secure the hog on its side with a loader

Hoisting and securing a bush hog on its side with a loader is one of the two ways to access the top of the blade bolts. This method is more complex and requires more safety precautions than the alternative, which involves sharpening the blades while the bush hog is still on the tractor.

To begin, ensure that the bush hog is securely rigged. It is highly recommended that two people work together on this process due to safety concerns. Once the hog is rigged, do not stand under or near it, as it may fall over.

After securing the hog, use the deck access hole to reach the top of the blade bolts. You may need to use extensions on your tools to reach both sides of the deck at the same time. Keep the hog stable while you work, and be sure to keep your body out of the way.

It is advantageous to have a correctly placed pick point on the mower deck for easy hoisting, which can be easily fabricated and welded on.

Use a sledgehammer to remove the blades from the shoulder bolt

Removing the blade pan from a bush hog can be a challenging task. The blade pan is the part of the mower that houses the blades and is responsible for their rotation. To remove the blade pan, you will need to first detach the blades from the shoulder bolt, which is a smooth-headed bolt that secures the blades in place. Here is a step-by-step guide on using a sledgehammer to remove the blades from the shoulder bolt:

Step 1: Prepare the Work Area

Before starting any work on your bush hog, ensure that you are wearing the appropriate safety gear, including heavy-duty work gloves and eye protection. Additionally, make sure that the bush hog is securely blocked up or hoisted to prevent any accidental movement or rolling.

Step 2: Access the Blades and Shoulder Bolt

Locate the blades and the shoulder bolt. In some bush hog models, there may be a cover or inspection hole in the deck that provides access to the blade assembly. If your bush hog has this feature, remove the cover to expose the blades and shoulder bolt.

Step 3: Understand the Blade and Bolt Mechanism

The blades of a bush hog are designed to rotate freely on the shoulder bolt. This allows the blades to move instead of breaking when they hit an object. The shoulder bolt typically has a key or tang built into it that fits into a corresponding keyway or slot in the drum or blade holder. This key prevents the bolt from turning.

Step 4: Use the Sledgehammer to Remove the Blades

Now, for the main task at hand—using the sledgehammer to remove the blades. Here's a suggested approach:

• Put the nut back on the shoulder bolt until it is flush with the end. This will provide a secure surface for the impact of the sledgehammer.
• Hold the sledgehammer firmly and swing it with controlled force onto the nut. The impact should transfer to the shoulder bolt, dislodging it from the blade assembly.
• If the blades are severely damaged or the bolts are seized, you may need to strike the sledgehammer directly onto the bolt or use a combination of other tools, such as a grinder or cutting torch.

Step 5: Exercise Caution

It is important to exercise caution when using a sledgehammer or any other tool to remove the blades. The force applied should be controlled and directed only at the intended target. Always be mindful of your surroundings and never stand directly under or near the path of the bush hog in case it falls or moves unexpectedly.

Removing blades from a bush hog can be challenging, and it is common for bolts to be destroyed in the process. Using a sledgehammer can provide the necessary force to dislodge the blades from the shoulder bolt. However, it is crucial to prioritize safety and stability throughout the process.
