Safety Information
Always prioritize safety when working with machinery. Failure to follow these safety instructions may result in serious injury or damage to equipment.
- Disconnect Power: Before performing any installation, maintenance, or repair, ensure the snowblower's engine is off and the spark plug wire is disconnected to prevent accidental starting.
- Wear Protective Gear: Always wear appropriate personal protective equipment, including safety glasses and gloves, to protect against sharp edges and moving parts.
- Use Correct Tools: Use only the recommended tools for installation and removal to prevent damage to the shave plate or snowblower.
- Inspect Components: Before installation, inspect the new shave plate and surrounding snowblower components for any damage or defects.
- Secure Fasteners: Ensure all bolts, nuts, and other fasteners are tightened securely according to the snowblower manufacturer's specifications.
Package Contents

Installation
This section outlines the steps for replacing the shave plate on your MTD snowblower. Refer to your snowblower's original owner's manual for specific instructions regarding component access and torque specifications.
Tools Required:
- Wrench set (appropriate sizes for snowblower fasteners)
- Socket set (appropriate sizes for snowblower fasteners)
- Safety glasses
- Work gloves
Procedure:
- Prepare the Snowblower: Ensure the snowblower is turned off, the engine is cool, and the spark plug wire is disconnected. Position the snowblower on a stable, level surface.
- Locate the Shave Plate: The shave plate is located at the bottom front edge of the snowblower's auger housing. It is a long, flat metal strip designed to scrape snow from the ground.
- Remove Old Shave Plate: Using the appropriate wrench or socket, carefully loosen and remove the bolts, nuts, and washers that secure the old shave plate to the auger housing. Keep track of all fasteners for potential reuse if they are in good condition.
- Inspect Mounting Area: Clean any debris, rust, or ice from the auger housing's mounting surface. Inspect the mounting holes for damage.
- Position New Shave Plate: Align the new Rotary 5592 shave plate with the mounting holes on the auger housing. Ensure it sits flush against the housing.
- Secure New Shave Plate: Insert the bolts through the shave plate and auger housing. Attach washers and nuts, then hand-tighten all fasteners. Once all fasteners are in place, progressively tighten them with a wrench or socket, ensuring even pressure. Do not overtighten.
- Final Check: Verify that the new shave plate is securely attached and properly aligned. Reconnect the spark plug wire.

Operation
The shave plate is a passive component that works in conjunction with the snowblower's auger. Its primary function is to scrape the surface of the ground, ensuring that the auger can pick up as much snow as possible. A properly installed shave plate helps maintain efficient snow removal and protects the auger housing from direct contact with the ground.
Maintenance
Regular inspection and maintenance of the shave plate are crucial for optimal snowblower performance and longevity.
- Inspect for Wear: After each use, or at least seasonally, inspect the shave plate for signs of wear, bending, or damage. The shave plate will naturally wear down over time as it scrapes against surfaces.
- Check Fasteners: Periodically check that all mounting bolts and nuts are tight. Loose fasteners can lead to excessive wear or detachment of the shave plate.
- Clean Debris: Remove any accumulated snow, ice, or debris from around the shave plate and auger housing.
- Replacement: Replace the shave plate when it shows significant wear, typically when it is worn down to approximately half its original width or if it is bent or damaged. Timely replacement ensures effective snow clearing and protects the auger housing.
Troubleshooting
If you experience issues related to snow clearing, consider the following:
- Poor Snow Clearing: If the snowblower is leaving a layer of snow on the ground, the shave plate may be excessively worn and require replacement.
- Excessive Vibration/Noise: A loose or damaged shave plate can cause unusual vibrations or noises. Inspect the plate and its fasteners for proper installation and condition.
- Damage to Auger Housing: If the shave plate is severely worn or missing, the auger housing may come into direct contact with the ground, leading to damage. Replace the shave plate immediately to prevent further damage.
