CenturionPro HP1 High-Performance Bucker

The CenturionPro HP1 High-Performance Bucker is a commercial de-stemming machine engineered for operations that need substantially greater throughput than compact tabletop systems can provide.

Capable of processing up to 175 pounds of wet plant material or 35 pounds of properly dried material per hour, the HP1 can replace the output of approximately five to seven manual workers. Its high-torque roller system allows operators to move through large harvest volumes while maintaining a controlled, repeatable workflow.

• Wet Processing Capacity: Up to 175 lbs/hr
• Dry Processing Capacity: Up to 35 lbs/hr
• Feed Openings: Five Sizes up to 3/4"
• Warranty: 5-Year Manufacturer Warranty

The HP1 uses two neoprene rubber rollers to grip each stem and pull it through the selected feed opening. This continuous pull-through process separates flower material quickly while reducing the repetitive effort, inconsistency, and labor requirements associated with hand bucking.

Five feed openings accommodate stems measuring 3/16 inch, 1/4 inch, 3/8 inch, 1/2 inch, and 3/4 inch in diameter. Operators can match each stem to the closest opening size, helping improve separation efficiency across a broad range of branch thicknesses without changing plates between batches.

A powerful 0.75 HP gear-driven motor supplies more than 400 pounds of pulling force. The motor is rated for continuous-duty operation and includes Variable Speed Control, allowing the pull rate to be adjusted between approximately 10 and 30 inches per second.

Lower speeds provide greater control for dry, brittle, or delicate material. Higher settings increase throughput for hydrated, flexible stems and larger commercial harvest loads.

Motor Pulse and Reverse Operation are also included. Pulse control supports short, deliberate roller movements, while reverse allows operators to release improperly fed or lodged material without immediately disassembling the processing head.

The HP1 includes both tabletop setup legs and a full commercial bucker stand. Operators can use the compact machine on a reinforced work surface or install it on the included stand for improved working height and facility integration.

The bucker stand comes equipped with industrial casters, allowing the system to be moved for cleaning, maintenance, storage, or alignment with downstream trimming equipment. Once positioned, the casters should be locked securely before operation.

Constructed from 304 stainless steel and anodized aluminum, the HP1 is built for durability, corrosion resistance, and straightforward sanitation. Its commercial components are designed to withstand repeated harvest cycles while remaining accessible for cleaning and routine inspection.

The HP1 operates from standard North American 120V single-phase power and draws less than 2.5 amps during operation. A dedicated 15A circuit is required. International models operate on 240V single-phase power.

For operations building a complete post-harvest line, the HP1 can be positioned ahead of compatible trimming, conveying, inspection, and collection equipment. Its 175-pound wet hourly capacity makes it a strong match for medium and large trimming systems where manual stem removal would otherwise become the primary production bottleneck.

Backed by a 5-year manufacturer warranty, the CenturionPro HP1 is designed for facilities that need powerful roller-driven processing, adjustable speed, multiple feed sizes, flexible tabletop or stand-mounted installation, and dependable commercial performance.

High-Performance Roller Bucking

The HP1 uses two neoprene rubber rollers to grip and pull stems through the selected feed opening. This high-performance system provides:

• Continuous stem feeding
• More than 400 pounds of pulling force
• Consistent separation
• Adjustable processing speed
• Wet and dry compatibility
• Reduced repetitive manual labor
• Commercial-scale throughput

Up to 175 lbs Wet Per Hour

The HP1 processes up to approximately 175 lbs/hr wet and 35 lbs/hr dry. Actual throughput depends on:

• Stem diameter
• Material moisture
• Branch preparation
• Plant structure
• Feed-hole selection
• Pull-speed setting
• Operator experience
• Machine cleanliness
• Downstream processing capacity

Replaces Up to 7 Manual Workers

Under suitable operating conditions, the HP1 can replace the output of approximately five to seven manual workers. This allows facilities to redirect staff toward:

• Branch preparation
• Material inspection
• Mechanical trimming
• Quality control
• Packaging
• Cleaning
• Inventory management

Five Feed Entry Sizes

The HP1 includes five feed openings: 3/16", 1/4", 3/8", 1/2", and 3/4". This broad range allows the machine to process delicate stems as well as thicker commercial branches without replacing the complete feed plate.

Accepts Stems Up to 3/4 Inch

The largest feed opening accommodates stems up to approximately 3/4 inch in diameter. Oversized, forked, or heavily branched sections should be cut down before processing to prevent binding and maintain consistent roller performance.

Integrated Variable Speed Control

Variable Speed Control comes standard with the HP1. Operators can adjust the pull rate based on the moisture, thickness, and structure of the material being processed.

Lower speeds support:

• Properly dried material
• Brittle stems
• Delicate flower structures
• Greater operator control
• Reduced breakage
• Careful separation

Higher speeds support:

• Wet material
• Flexible stems
• Dense harvest loads
• Continuous feeding
• Greater hourly throughput
• Faster commercial processing

Adjustable Pull Speed

The HP1 provides an approximate pull-speed range of 10 inches per second at lower settings up to 30 inches per second at higher settings. Operators should begin at a slower setting and increase the speed gradually after confirming that the material separates cleanly.

More Than 400 lbs of Pull Strength

The roller drivetrain delivers more than 400 pounds of pulling force. This gives the HP1 the torque required to process thick stems and high-volume harvest loads without relying on manual pulling strength. Hands, tools, loose clothing, and jewelry must always remain clear of the feed openings and rollers.

High-Torque 0.75 HP Motor

The HP1 uses a 0.75 HP, IP54-rated gear-driven motor operating at approximately 1,690 RPM. The motor supports continuous-duty operation, high pulling force, variable-speed processing, wet and dry material, thick commercial stems, and consistent roller movement.

Motor Pulse Control

Motor Pulse allows the rollers to move in short, controlled increments. This can help operators:

• Position difficult stems
• Manage short branch sections
• Clear minor feed resistance
• Improve control during setup
• Reduce unnecessary continuous movement

Reverse Operation

Reverse Operation allows the roller direction to be changed when necessary. This is useful for releasing lodged material, correcting an improper feed, clearing a branch safely, reducing unnecessary disassembly, and restoring normal workflow. Reverse mode should only be used according to the owner’s manual.

Neoprene Rubber Rollers

The HP1 uses a dual-roller set manufactured from neoprene rubber. Neoprene provides:

• Strong stem grip
• Controlled pulling action
• Reliable wet and dry performance
• Reduced metal-to-material contact
• Commercial durability
• Replaceable wear surfaces

Wet and Dry Processing

The HP1 is designed to process both wet and properly dried plant material. Wet stems are generally more flexible and can support faster pull rates. Dry stems require slower feeding and greater care to reduce breakage and protect the finished material.

Continuous-Duty Operation

The HP1 is built for continuous commercial harvest cycles. Its motor, roller system, and drivetrain support extended operation when the machine is cleaned, inspected, and maintained according to manufacturer instructions.

Tabletop and Stand-Mounted Operation

The HP1 includes both tabletop setup legs and a full commercial bucker stand. The tabletop configuration provides a smaller footprint for facilities with reinforced work surfaces. The stand-mounted configuration provides improved working height, easier mobility, and better integration into a permanent processing line.

Included Commercial Bucker Stand

The included stand provides stable operating height, structural support, better operator ergonomics, space for material collection, easier workflow integration, and mobile facility placement.

Industrial Casters

The stand is mounted on industrial casters. This allows the HP1 to be repositioned within the facility, moved for cleaning, rolled into storage, aligned with downstream equipment, shifted for maintenance, and locked securely during operation. All caster locks should be engaged before startup.

Optional Off-Road Wheel Assembly

An Off-Road Wheel Assembly Kit may be available for facilities that need to move the HP1 over rougher terrain or between field and indoor processing areas. This upgrade provides greater mobility than standard industrial casters but does not eliminate the need for a stable, level operating surface.

Commercial-Grade Construction

The HP1 is built primarily from:

• 304 stainless steel
• Anodized aluminum
• Neoprene rubber rollers
• Commercial bearings
• Gear-driven motor components
• Heavy-duty stand hardware
• Industrial caster assemblies

These materials support regular cleaning, corrosion resistance, and repeated commercial use.

Standard 120V Operation

North American electrical requirements include 120V, 60 Hz, single phase, approximately 5A rated input, less than 2.5A operating draw, and a 15A circuit breaker. International requirements include 240V, 50 Hz, single phase, approximately 2.5A rated input, and a 15A circuit breaker. Installation must follow manufacturer instructions and applicable electrical codes.

Extension Cord Requirements

When an extension cord is necessary, the manufacturer specifies a minimum of 14 AWG and a maximum length of 25 feet. Using an undersized or excessively long cord may result in voltage loss, overheating, or inconsistent motor performance.

Compliance-Focused Design

The supplied manufacturer information identifies the HP1 as GMP compliant, UL compliant, CE compliant, and RoHS compliant. Facilities should still verify all local electrical, workplace, sanitation, and processing requirements before installation.

Streamlined Processing Integration

The HP1 can be positioned at the beginning of a larger processing workflow. A typical setup may include:

• Branch preparation
• HP1 de-stemming
• Material collection
• Visual inspection
• Mechanical trimming
• Final quality control
• Packaging and storage

Balancing the HP1 with the capacity of downstream equipment helps prevent production bottlenecks.

Optional HP1 Parts Kit

The HP1 Parts Kit helps facilities keep critical replacement components available during harvest. The shared HP1/HP3 kit may include:

• Two HP roller assemblies
• Five front cut-plate assemblies
• Two compression springs
• One 25-tooth spur gear
• One 25-tooth no-collar spur gear
• Two HP slide bearings
• One parts assembly kit

Keeping these components available can reduce downtime during cleaning, routine wear, or maintenance. Selectable above.
