At the heart of the Evolution Separator are the spiral rollers, the key component responsible for separating soil, clods, and haulm from your crop while handling it gently.

How Spiral Rollers Work and Self-Clean

The spiral roller works with the following clod roller (‘P roller’) and has two main jobs: extracting haulm/leaf matter and everything else (clods, stones, and soil).

• Extracting haulm: The flat-topped, stiff ribs pinch stems firmly against the clod roller without bunging root balls. A small gap (1mm) is enough, there is no need to press the rollers tightly together, which can cause premature wear.
• Extracting clods, stones, and soil: The rib tread “nibbles” at irregular clods and pulls them down between rollers. Large air chambers allow the roller to deform around hard clods and stones, minimising losses and preventing soil buildup.
• Self-cleaning: This occurs when the roller deforms regularly and has enough inertia (we recommend around 130RPM in wet conditions). This action naturally flings mud and debris off the roller.

Choosing the Correct Roller

Least Aggressive – 4 Rib 6mm Spiral Roller

Best for: Small or delicate crop and lighter conditions

Why choose it: The less aggressive tread prevents pinching or damage and is ideal for lighter, drier soils. Aggressiveness can be increased when needed by running the clod rollers in reverse (operated in pairs).

Moderately Aggressive – 6 Rib 10mm Spiral Roller

Best for: Standard main crop and variable conditions

Why choose it: More pronounced ribs and smaller body diameter ensure excellent soil and clod separation. Provides flexibility to reduce aggressiveness in light or dry conditions while still being capable of removing large volumes of clod, soil, and haulm when conditions turn more challenging.

Most Aggressive – 3 Rib 15mm Spiral Roller

Best for: Small or delicate crop and lighter conditions

Why choose it: The less aggressive tread prevents pinching or damage and is ideal for lighter, drier soils. Aggressiveness can be increased when needed by running the clod rollers in reverse (operated in pairs).

Combining Roller Types

It is possible to combine spiral roller types. For example, on a 6-row machine, the first two rows could use 6 Rib 10mm rollers, while the remaining four rows use 4 Rib 6mm rollers, as the highest volume of soil is typically at the beginning of the machine.

Note: Only one roller type can be fitted per shaft.

Roller Colours and Shafts

Shaft sizes: 40mm (machines up to 2.0m) and 45mm (machine 2.0m+)

Roller colours:

• Blue – for optical sorter detection
• Light grey – 40mm shafts
• Dark grey – 45mm shafts

Additional Features

• Segment lengths: Standard 171mm, with shorter options at 122mm and 100mm
• Transfer rollers: Soft polyurethane with a slight rib to lift and carry stones efficiently

Key Takeaway

Selecting the right spiral roller depends on soil type, season, and machine configuration. From light handling to extreme conditions, the Evolution Separator’s range of spiral rollers ensures optimal cleaning performance, crop protection, and reliability.

As winter winds down and spring fieldwork approaches, now is the ideal time to review your Scotts machinery and plan any servicing before workloads increase. After months of use, small signs of wear can appear that aren’t always obvious but addressing them now can prevent costly downtime later.

For many farms and processors, this post-winter period provides a valuable window between busy seasons. Equipment that has worked hard may show wear on bearings, belts, chains, hydraulic systems and moving parts. Identifying these issues now ensures your machinery is ready for the season ahead.

Even if everything seems fine, minor changes in performance, such as unusual noise, vibration, reduced throughput, or extra operator adjustments can signal components that need attention. Observing your machinery during this quieter period allows you to plan service efficiently, rather than reacting to breakdowns during peak work.

Practical Checks You Can Do Now

• Visual inspections: bearings, belts, chains, rollers, wiring, hydraulic hoses.
• Operational checks: listen for unusual sounds, monitor throughput, check safety features, verify lubrication.
• Maintenance tasks: replace worn parts, tighten fixings and clean machinery thoroughly.

Plan Ahead for Servicing and Parts

Technician availability can become limited as the season progresses. Booking inspections and parts now ensures your machinery is ready when you need it. Our Scotts service team can help with:

• Pre-season inspections and servicing
• Wear-part replacement
• Maintenance advice tailored to your equipment
• Scheduling workshop time before peak demand

Set Your Operation Up for a Productive Season

Taking the time now to inspect and maintain your machinery helps:

• Protect uptime
• Extend equipment life
• Keep operations running smoothly when workloads increase

By identifying minor issues early, planning service, and securing parts in advance, you can enter the new season with confidence.

The landmark 1,000th machine has been delivered to a British grower, highlighting the strong loyalty and trust Scotts continues to enjoy in its home market as well as overseas.

The success of the Evolution Separator has been central to Scotts’ growth as a company. Demand for the machine has seen the factory size double in recent years, and the team now numbers around 25 staff, a dedicated group of people whose skill and hard work have made this achievement possible. Further expansion plans are already underway as the business looks to the future.

Derek Scott, Managing Director of Scotts Precision Manufacturing, reflected on the milestone:

“This is more than just a number, it’s a moment that makes us pause and look back at the journey. When we launched the Evolution Separator in 2005, we wanted to give growers something that genuinely made their lives easier, their crops cleaner, and their businesses more efficient. To see 1,000 machines now out in the world, helping farmers and processors every day, is humbling. None of this would have been possible without the trust of our customers, who put their faith in us, and the dedication of our team here at Scotts, who pour their energy and expertise into every machine we build. I’m incredibly proud of what we’ve achieved together.”

Looking ahead, Scotts remains committed to driving innovation.

Scotts Precision Manufacturing Ltd, a leading designer and manufacturer of root crop and vegetable cleaning and harvesting systems for global markets, proudly announces the launch of its new pre-cleaner, the Terra-Siv.

The self-cleaning Terra-Siv is specifically designed to rapidly extract large volumes of loose soil and debris over a very short distance. Designed to either bolt directly onto the intake of any of our second-generation Evolution Separators or used as a stand-alone pre-cleaner.

Derek Scott quotes, “The main driver for this design is to assist customers dealing with high soil percentages in their crops. Most growers of overwintered carrots and parsnips already use our highly successful Evolution Separator. The Terra-Siv will turbocharge these separators by removing high levels of loose soil and smaller debris. By eliminating this debris beforehand, the separator can operate more efficiently, removing larger particles and leaf matter. The versatility of the system provides equal benefits for a wide variety of other crops, such as potatoes, onions, celeriac, and beets.”

How It Works.

The crop is supported on the tips of the stars, allowing loose soil to immediately fall between the fingers, while larger particles are drawn down into the valley between the star shafts. We have found that by mis-matching the star shaft speeds and adjusting the height of the second star shaft we can then effectively entrain irregular shaped objects deeper into that valley without pulling the crop through. The key is to eliminate any flex or movement within the shafts and supporting chassis while keeping the star fingers open in the heaviest of soils. This was achieved by stabilizing the spacing between the stars. Having uniform star spacings allows us to maintain a very tight tolerance between the cleaning finger and adjacent stars. The use of a square-edged steel finger ensures the gap is repeatedly cleaned, twin roller bearings mounted on a cam shaft consistently flex the soft fingers, completing the self-cleaning cycle.

The design is focused on low maintenance and tool-free adjustment. Direct drive electric motor/gearboxes, along with remote greasing, are fitted as standard. For operator ease, all adjustments are made via push button or turnbuckles.

The unit consists of six individually direct-driven shafts, providing the following functionalities;

1. The first variable-speed “feed-on roller” (height adjustable by turnbuckle) offers a gentle landing for the crop and fixes the overall length of the separator.
2. The following star shaft, adjustable for speed, can be adjusted rearward by an electric linear ram to create a gap of up to 65mm (the “feed-on shaft” moves vertically to allow this).
3. The second star shaft is individually adjustable for speed and height.
4. The final soft “feed-off roller” is adjustable for speed and direction.
5. Below each star shaft is a highly efficient cleaning system, comprising of a slowly rotating cam shaft with single steel fingers passing between each pair of stars to constantly eliminate any buildup of soil. Between each steel finger, a double bearing mounted on a small hub rotates with each shaft, effortlessly flexing each finger to loosen compacted soil that builds up between the front and rear of each star finger.
