Installing a grinder attachment on your skid steer loader can dramatically expand the versatility of your machine. From clearing tree stumps to preparing construction sites, a properly installed grinder ensures efficient, safe, and smooth operation. This guide is designed for contractors, equipment operators, and DIY users who want a straightforward approach to getting their grinder up and running.
How to Install a Grinder on a Skid Steer Loader: A Step-by-Step Guide
In this guide, we’ll use the AHM Stump Grinder Attachment as an example. Installation steps may vary depending on your skid steer model and grinder attachment, so always follow the instructions provided in your equipment’s manual.
The installation process can be divided into three main parts: Removing the Current Attachment, Attaching the Stump Grinder, and Connecting the Hydraulic Hoses.
Part 1 Removing the Current Attachment
Note: This part only provides general guidance on the loader’s current attachment removal. For more specific information, refer to your skid steer loader’s manual or your attachment’s manual.
If the current attachment on your skid steer loader does not require hydraulic power, follow Regular Attachment below to remove it; if it does, follow Hydraulic Attachment.
Regular Attachment
1. Start the engine of the skid steer loader following the normal protocols.
2. Stand the attachment vertically by pushing the right control rod left a small amount.
3. Lay the attachment on the level ground by pushing the left control rod left.
4. Shut the engine.
5. Release the coupler locking mechanism by pulling up the lock pin handles on the mount plate and turning them away from the center of the attachment.
6. Remove the freed attachment using at least two people.
Hydraulic Attachment
Warning：Wear gloves and other protective gear, and use EXTREME care when handling the
hydraulic hoses, which may remain hot enough to cause skin burns. ALWAYS set the attachment control rod neutral before handling the hoses.
1. Start the engine of the skid steer loader following the normal protocols.
2. Stand the attachment vertically by pushing the right control rod left a small amount.
3. Lay the attachment on the level ground by pushing the left control rod left.
4. Shut the engine.
5. Move all the control rods back and forth to release any built-up pressure, and then set them neutral.
6. Wait until the engine and hydraulic oil have cooled to ambient temperature.
7. If the hydraulic connections have retaining clips, remove them first.
8. Disconnect all the hydraulic hoses that connect your skid steer loader to the hydraulic system of the current attachment by releasing their couplers.
9. Release the coupler locking mechanism by pulling up the lock pin handles on the mount plate and turning them away from the center of the attachment.
10.Remove the freed attachment using at least two people.
Part 2 Attaching the Stump Grinder
Note:
- Ensure that the stump grinder and the mount plate of your skid steer loader are free of dirt and debris.
- Use level ground to install the stump grinder. If the ground is not level, use wood blocks to help.
- Use at least three people to move the stump grinder. If possible, use a forklift.
1. Unpack the stump grinder and lay it on a level, stable surface.
2. Start the engine of the skid steer loader following the normal protocols.
3. Drive the skid steer loader to the rear of the stump grinder.
4. Angle the mount plate to hook the stump grinder’s quick-attach. Tilt the mount plate backward a bit until it is fully engaged in the mount plate.
5. Stop the engine and engage the parking brake.
6. Secure the coupler locking mechanism by pulling up the lock pin handles on the mount plate and turning them to the center of the attachment. Ensure that the lock pins have been inserted into the axis pin holes on the quick-attach coupler.
Part 3 Connecting the Hydraulic Hoses
Warning：Wear gloves and other protective gear, and use EXTREME care when handling the
hydraulic hoses, which may remain hot enough to cause skin burns. Ensure that the hydraulic couplers are free of dirt and debris.
1. Shut the engine.
2. Move all the control rods back and forth several times so that there is no residual pressure at the hydraulic couplers.
3. Ensure that all controls are in neutral.
4. Wait until the engine and hydraulic oil have cooled to ambient temperature.
5. Open the cap and connect the male coupler of one hydraulic hose on the stump grinder to the female coupler on the loader by inserting the male coupler.
6. Open the cap and connect the female coupler of the other hydraulic hose on the stump grinder to the male coupler on the loader by inserting the female coupler.
7. Arrange the hydraulic hoses as needed to ensure they are not at risk of damage or interfering with operations.
8. Test the stump grinder and make sure you have enough hose length to perform the full range of the loader’s operating heights, but be careful not to over-extend the cylinders.
9. Visually check for any hydraulic oil leak. If there is, repeat steps 1–4 and redo the connection where the leakage is.
