A Reliable, All-Around Solution for Yard Cleanup

Best For

• Homeowners with ½ to 3+ acre properties
• Heavy seasonal cleanup (leaves, pruning, storm debris)
• Processing branches up to 3-1/2″ diameter
• Turning yard waste into mulch or compost
• Buyers looking for durability over disposable equipment

What It Does

• Leaves and yard debris
• Tree branches and brush
• Garden waste and stalks
• Storm cleanup material
• Organic material for mulching and composting

Why the 12P is Different

• Hammermill Shredding System
  24 free-swinging, heat-treated hammers allow the machine to process a wider range of material more efficiently than fixed-blade systems.
• Heavy-Duty Steel Flywheel
  Precision-balanced for smoother operation, consistent chipping, and reduced vibration.
• Centrifugal Clutch Drive
  Makes starting easier and helps protect the engine under load by allowing it to disengage when needed.
• Reversible Wear Components
  Hammers can be rotated multiple times to extend service life and reduce maintenance costs.
• Wide-Opening Hopper with Blowback Shield
  Supports fast loading while helping control material during operation.

Key Specifications (Quick View)

• Chipping capacity: up to 3-1/2″ diameter
• Shredding capacity: up to 1″ material
• Hammer count: 24 free-swinging hammers
• Flywheel: 12″ steel, precision balanced
• Engine options: Briggs & Stratton or Honda (model dependent)

Key Features

• Large-capacity shredder hopper for bulk material
• Dedicated chipper chute for branches and limbs
• Optional screens to control output size
• Towable or maneuverable depending on model configuration
• Built for year-round property maintenance

The 12P is designed to process a wide range of common yard and property debris. From seasonal cleanup to ongoing maintenance, it handles both bulky material and lighter organic waste in one machine.

Leaves, Yard Debris, and Bulk Cleanup

• Dry leaves, pine needles, and lawn debris
• Garden waste and plant material
• Seasonal cleanup from fall and spring

The large shredder hopper allows you to process high volumes of lighter material quickly, making it well-suited for routine property maintenance and seasonal cleanup.

Branches and Woody Material

• Tree branches up to 3-1/2″ diameter
• Brush, trimmings, and pruning debris
• Storm cleanup material

The dedicated chipper chute is designed for feeding branches and woody material efficiently, producing consistent chips for disposal or reuse.

Garden Waste and Organic Material

• Stalks, vines, and plant matter
• Spent garden material and compost inputs
• General organic debris

This makes the 12P a practical tool for reducing garden waste into material that can be reused for mulch or compost.

Material Size & Output Control

• Includes a standard 1″ screen
• Optional screens available for different output sizes

Screen size affects both how fine the material is processed and how quickly it moves through the machine.

• Smaller screens → finer material, slower throughput

• Larger screens → faster processing, coarser output

Working With Wet or Heavy Material

• Damp or heavy material can be processed with proper feeding
• Slower feed rates improve performance
• Larger screen sizes help prevent clogging

For best results, avoid overloading the machine and allow the hammermill to process material at its own pace.

What It’s Not Designed For

• Large logs or material beyond rated capacity
• Rocks, metal, or non-organic debris
• Extremely wet, compacted material in large volumes

Using the machine within its intended capacity ensures better performance and longer component life.

Compare: 12P vs SC1650

Choosing the right machine comes down to how much material you’re processing, how often you’re using it, and how heavy the workload is.

Choose the 12P if:

• You’re maintaining a residential property (½ to 3+ acres)
• Your cleanup is seasonal or periodic, not constant
• You’re processing mixed material (leaves, brush, branches)
• You want a versatile machine without stepping into commercial size and cost
• You value maneuverability and easier storage

👉 The 12P is the right balance of power and practicality for most homeowners.

Choose the SC1650 if:

• You have larger properties or heavier workloads
• You’re processing higher volumes of material regularly
• You need more throughput and faster processing
• You’re dealing with more demanding or continuous use conditions
• You want a machine closer to commercial-grade performance

👉 The SC1650 is built for higher output and more demanding, frequent use.

Key Differences at a Glance

12P

• Up to 3-1/2″ chipping capacity
• 24 hammer design
• Lighter, easier to maneuver
• Ideal for seasonal and recurring cleanup

SC1650

• Larger capacity and heavier-duty construction
• More hammers / higher processing capability
• Designed for higher volume throughput
• Better suited for frequent or demanding workloads

Still Not Sure?

If your cleanup is:

• Occasional or seasonal → 12P is typically the better fit
• Frequent, heavy, or ongoing → SC1650 is worth the step up

If you’re between the two, most customers choose the 12P for flexibility, unless they know they need higher volume processing.
