1. Overview for vibratory plate compactor attachments for skid steer loaders
Plate compactor attachments (also called vibratory plate compactors or compaction plates) transform a skid steer loader into a powerful soil and material compaction tool. They use hydraulic power from the skid steer’s auxiliary circuit to create rapid vertical vibrations through a heavy steel plate — effectively compacting soil, gravel, asphalt, or trench backfill.
2. Key Components
| Component | Description |
|---|---|
| Base Plate | The flat, hardened steel surface that directly contacts the material being compacted. Sizes vary (typically 18–30 inches wide). |
| Eccentric Vibrator / Exciter | A motor-driven offset weight system that creates vibration by spinning at high speed. Controlled by the skid steer’s hydraulics. |
| Hydraulic Motor | Converts the skid steer’s hydraulic flow into mechanical rotation for the vibrator assembly. |
| Mounting Frame / Adapter | Connects the compactor to the skid steer’s quick attach plate. Some models allow tilt or swivel functions for angled surfaces. |
| Rubber Isolators | Absorb excess vibration between the base plate and mounting frame to protect the loader’s arms and operator. |
| Flow Control / Relief Valve | Regulates hydraulic pressure to prevent damage from excessive flow or back pressure. |
3. Hydraulic System Requirements
Plate compactors depend heavily on correct hydraulic setup. Always match the unit’s hydraulic specs to your skid steer’s auxiliary circuit.
| Parameter | Typical Range | Notes |
|---|---|---|
| Hydraulic Flow (GPM) | 8–30 GPM | High-flow models offer faster and deeper compaction. |
| Operating Pressure | 2,000–3,500 PSI | Verify compatibility with the skid steer’s system pressure. |
| Return Line Pressure | <250 PSI | Backpressure above this can damage the motor. |
| Hydraulic Couplers | Flat-face couplers recommended for easy clean connection and minimal leaks. |
Tip: Incorrect flow or pressure can cause poor vibration or premature seal failure.
4. Plate Sizes and Force Ratings
| Application | Plate Width | Centrifugal Force | Frequency | Ideal Material |
|---|---|---|---|---|
| Trench Backfill / Pipe Bedding | 12–18 in | 3,000–6,000 lb | 2,000–2,500 vpm | Sand, gravel, cohesive soil |
| General Earthwork / Roadwork | 18–24 in | 6,000–10,000 lb | 2,200–2,800 vpm | Clay, gravel, mixed fill |
| Heavy Construction / Large Pads | 24–30+ in | 10,000–15,000+ lb | 2,000–3,000 vpm | Rock, asphalt, deep compaction |
5. Mounting Options
- Direct Mount (Standard Quick Attach):
- Bolts directly onto the skid steer’s universal quick plate.
- Best for ground-level compaction.
- Excavator-Style Mount (Optional Adapters):
- Allows attachment to mini-excavators or backhoes.
- Ideal for trench or slope compaction.
- Swivel Mount / Tilt Bracket:
- Enables compaction at angles or around obstructions.
- Increases efficiency in confined areas or slopes.
6. Operating Technique
- Warm-Up: Run hydraulics for 2–3 minutes before engaging vibration.
- Engage Slowly: Activate vibration at low throttle, then increase gradually.
- Maintain Contact: Keep the plate flat; avoid bouncing.
- Pass Overlaps: Overlap each pass by 6–8 inches for uniform compaction.
- Avoid Over-Vibration: Excessive vibration can loosen material instead of compacting.
- Monitor Temperature: Stop operation if hydraulic oil exceeds 180°F (82°C).
7. Maintenance and Safety
| Task | Frequency | Details |
|---|---|---|
| Inspect hydraulic hoses | Daily | Check for leaks, abrasion, or swelling. |
| Grease bearings / pivot points | Every 8 hours | Prevent premature wear in vibrator shaft. |
| Check exciter oil level | Weekly | Replace with manufacturer-specified gear oil. |
| Torque bolts and fasteners | Weekly | Vibration can loosen connections. |
| Replace isolators | As needed | Cracked isolators increase vibration transmission. |
Safety Tips:
- Never operate near unsupported trench walls.
- Avoid standing within vibration radius when engaged.
- Always disconnect hydraulics before service.
8. Applications
✅ Road base and subgrade compaction
✅ Asphalt patching and repair
✅ Pipeline backfill and utility trenches
✅ Retaining wall preparation

10. Selection Criteria
When choosing a plate compactor attachment:
- Match hydraulic flow and pressure to your skid steer.
- Choose plate size based on material and area.
- Consider frequency and force for soil type.
- Prioritize isolator quality for operator comfort.
- Check for tilt/swivel options if working on slopes or irregular terrain.
- Ensure aftermarket support (seals, bearings, isolators).
11. Performance Formula (Simplified)
To estimate compaction efficiency: Compaction Energy (ft\cdotplb/min)=Centrifugal Force (lb)×Amplitude (in)×Vibration Frequency (vpm)\text{Compaction Energy (ft·lb/min)} = \text{Centrifugal Force (lb)} \times \text{Amplitude (in)} \times \text{Vibration Frequency (vpm)}Compaction Energy (ft\cdotplb/min)=Centrifugal Force (lb)×Amplitude (in)×Vibration Frequency (vpm)
Higher energy = deeper and faster compaction, but excessive force can damage surface layers or buried structures.
Skid steer plate compactors consist of several key components that work together to produce compaction force:
- Vibratory plate: The heavy, flat steel plate that makes contact with the ground to compress the material.
- Hydraulic motor: A hydraulic motor, powered by the skid steer’s auxiliary hydraulics, drives an eccentric weight system.
- Eccentric weight system: Contains unbalanced weights that rotate at high speed, generating the vibratory force.
- Isolators (shock mounts): Heavy-duty rubber mounts that isolate the skid steer and operator from the vibrations produced by the compactor.
- Mounting plate: Attaches to the skid steer’s quick-attach system for easy connection.
Hydraulic requirements
For optimal performance, your skid steer must be compatible with the attachment’s hydraulic needs. High-flow hydraulic systems are generally not required for standard plate compactors, but you should always confirm the recommended GPM (gallons per minute) and PSI (pounds per square inch) ratings in the specific attachment’s manual.
Installation and preparation
Proper installation and site preparation are essential for safety and performance.
Step 1: Pre-operation checks
Before attaching the compactor, perform a walk-around inspection.
- Attachment inspection: Check the compactor for loose fasteners, hydraulic leaks, or damage. Inspect the shock mounts for any signs of cracking or tears.
- Carrier inspection: Ensure your skid steer has adequate hydraulic fluid and that its hydraulic quick-couplers are clean.
Step 2: Attachment procedure
- Lower and level: Lower the skid steer’s lift arms and tilt the quick-attach plate forward.
- Align and connect: Line up the attachment’s mounting plate with the skid steer’s coupler. Tilt the coupler back to lift the compactor and ensure the top bar engages.
- Engage pins: Activate the coupler’s locking pins to secure the attachment. Tilt the attachment back and forth to ensure the pins are fully seated.
- Connect hoses: Connect the compactor’s hydraulic hoses to the skid steer’s auxiliary hydraulic couplers. Ensure the connections are clean to prevent contaminants from entering the hydraulic system.
Operation guidelines
Step 1: Start-up
- Lower to the ground: With the attachment securely mounted and the hoses connected, lower the compactor until the entire plate is in full contact with the material to be compacted.
- Idle engagement: Engage the skid steer’s auxiliary hydraulics at a low engine speed to prevent premature coupler wear.
- Increase RPM: Gradually increase the engine RPM to achieve maximum vibratory force. Do not exceed the attachment’s recommended RPM limit, as this can cause overheating.
Step 2: Compacting techniques
- Apply light pressure: Allow the compactor’s weight and vibration to do the work. Pressing down too hard with the skid steer’s hydraulics will not improve compaction and can damage the machine.
- Work in strips: Move the skid steer slowly and steadily in overlapping strips to achieve uniform compaction.
- Maintain moisture: A small amount of moisture in the soil is necessary for optimal compaction, but excessive water can cause the material to stick to the compactor plate. On very dry surfaces, you can add water to the ground material to aid compaction and reduce dust.
- Use the right lift: For deep or dense materials, use several shorter, overlapping lifts rather than one thick layer.
Step 3: Shut-down
- Return to idle: Before disengaging the hydraulics, reduce the skid steer’s engine speed to idle.
- Disengage hydraulics: Turn off the auxiliary hydraulics.
- Release pressure: With the skid steer off, cycle the auxiliary hydraulic levers to relieve pressure in the lines before disconnecting the couplers.
Safety protocols
- Wear PPE: Always use appropriate Personal Protective Equipment (PPE), including hearing protection, gloves, safety glasses, and steel-toed boots.
- Clear the area: Ensure all bystanders are a safe distance away from the work area.
- Stay inside the cab: Do not exit the cab while the engine is running or the attachment is raised. Never allow riders in or on the loader.
- Keep visibility clear: Travel with the attachment low to the ground for maximum stability and visibility.
- Maintain stability: Operate on stable, level ground whenever possible. When on slopes, travel straight up and down, not across.
Maintenance schedule
Daily inspection
- Check for leaks: Look for hydraulic fluid leaks on hoses and connections.
- Inspect shock mounts: Check the rubber isolators for any signs of cracking or tears. If cracks appear at the top outer crease, rotate the mounts 180 degrees.
- Clean the plate: Scrape any built-up dirt, mud, or asphalt from the underside of the compactor plate to maintain efficiency.
- Check couplers: Clean the quick-couplers before every use to prevent debris from contaminating the hydraulic system.
Every 40 hours
- Lubricate bearings: Follow the manufacturer’s manual to lubricate the bearings on the eccentric weight system.
Seasonal/Long-term storage
- Clean thoroughly: Before storing, clean the entire attachment, paying close attention to debris around motors or hydraulic components.
- Relieve pressure: To prevent pressure buildup in the lines, connect the male and female hydraulic couplers together before storage.
- Protect from elements: Store the compactor in a dry, secure location to prevent rust and damage.
