The Rotastar™ is a unique, high-output screening bucket that combines market-leading features.
Material is constantly rotated, without any chopping or pinching, making screening of damp, fragile and special materials possible. Suitable for top soil, waste, turf, roots, gypsum, knotweed and many other applications.
The Rotastar™ bucket has a unique screening action. It rotates the material in a similar manner to a trommel screen, but has the benefit of rotating star discs, agitating and clawing at the material as it turns. This is achieved by mounting star shafts on a large arc, forming the back and top of the bucket.
The impressive performance of the Rotastar™ comes from:
Stars
Material is constantly rotated, without any chopping or pinching, making screening of damp, fragile and special materials possible. Suitable for top soil, waste, turf, roots, gypsum, knotweed and many other applications.
Speed
Variable speed control is fitted as standard up to the RS10-20, so it is possible to adjust fragment size by changing shaft speed. Most importantly, this allows the operator to set the shaft speed to suit conditions and requirements.
Fraction Size Reduction
With different star and collar options it is possible to reduce fine fraction size from the standard 20mm to 15, 10 and 8mm. The innovative Lloyd split-collar enables the user to set the bucket to 15 or 10mm without removing the shafts. The collars can also be removed quickly, returning to standard set up.
Combs
Top and bottom combs are available. Filling the gap between the apron, top scraper and star, they are normally used in combination with fraction size reduction kits. Manufactured from polyurethane to minimise adjacent star wear.
Spacers
To create a larger fraction size, spacers can be fitted between each star. Bark and compost are two popular applications for spacers. Additional shafts can be supplied with a specific set up, and quickly fitted to any bucket.
Transmission
Heavy duty chain drive powered by hydraulics is rugged and reliable. Simplicity is key, standard parts, easy maintenance and quick shaft removal.
Guard
The well protected, simple, sealed guard design, primarily on one side, offers easy inspection and fast maintenance of shafts and transmission.
Finish
All fabricated parts are shot blast and receive 4 coats of 2 pack paint. This provides good longevity and presentation.
Tube
The tube is a key part of the Rotastar™ design. Combined with the formed headstock, forces are transmitted effectively from machine to the cutting edge and body of the bucket.
Headstock
The formed headstock is a key part of the Rotastar™, perfect geometry giving good handling and optimised screening angles/position.
Area
Due to the light weight of the polyurethane stars, it has been possible to create a massive screening area when compared to bucket weight. High output, combined with efficiency and product quality.
Arc
The rotary action of the bucket allows complete mixing of material as it is being screened, ensuring complete separation. The bucket is screening throughout its cycle, with no time wasted in stopping and reversing the shafts.
Discs
Replaceable side panels work against replaceable shaft end discs. The area where the rotating star meets the fixed side panel has a unique design, with steel discs fitted to the shaft ends. This ensures even star wear across the shaft length, and closes the gap between star and side panel to maintain a genuine fraction size.
Quiet
The polyurethane stars ensure quiet running when compared to static and steel disc machines. A big benefit on sensitive sites.
Fabrication
Rugged construction, using the best design and materials for long life and reliability. High percentage of robot welding used in the Rotastar™ for efficiency and quality.
Maintenance
Easy maintenance. The complete design of the Rotastar™ allows for easy shaft removal. The polyurethane stars are an inexpensive, easily replaceable, part that reduces down time. Bearings are sited away from contamination and easy to grease.
Shafts
The shafts operate in one direction only and require a standard one-way hammer circuit. This also eliminates the need for a drain line. Shafts are designed for specific load, from hollow lightweight shafts on the smaller models to 50 x50mm high strength solid section on the larger models.
Loader
There are loader bracket options from the RS2-4 to RS 13-20. The loader bracket has a quick hitch design, so that the bucket can also be used on an excavator without the additional weight of the loader bracket. The RS 25-30 and RSLS 12-20 include loader brackets as standard.

The impressive performance of the Rotastar™ comes from:
STARS Lightweight, hard-wearing, flexible, self-cleaning polyurethane stars. This means no pinch or crushing areas, resulting in low power requirement and no contamination from crushed material. The flexible stars have a repelling finger profile, gentle on fragile material such as roots, vegetation and turf.
SPEED Variable speed control is fitted as standard up to the RS10-20, so it is possible to adjust fragment size by changing shaft speed. Most importantly, this allows the operator to set the shaft speed to suit conditions and requirements.
