ScanStone has announced the release of its new TriStar destoner models. Based on the chassis of the company’s four-web machines, the TriStar is available in narrow (1,540mm) and wide (1,740mm) working widths.

The TriStar carries on with the award-winning open front system with large front discs that are hydraulically controlled. The pressure can be set by the operator depending on ground conditions and the discs always float to the contour of the ground. The share can be multi blade or full width.

The key to the TriStar’s performance is the configuration. After the share it goes onto a front digger web, followed by three rows of fixed stars. The stars help break down any clod and help convey material through the rest of the machine, over the webs.

The main advantage on the ScanStone, and often referred to as the trademark of the company’s destoner range, is the front intake web, this limits the wear on stars down at the front of the machine and drastically reduces running costs.

After the stars, the soil moves onto a second web followed finally by a rear web. This combination of stars and webs offers operators excellent performance in varying soil conditions. The TriStar comes as standard with a hydraulically driven scrubber web that rotates over the rear web. The driven scrubber has varying pressure, speed and direction for heavy clay or light soil with high stone content.

The new TriStar is operated using ScanStone’s latest Advanced Control System that has a number of automated functions included a Headland Management System (HMS). This allows seamless row-in/row-out functionality, allowing the operator to focus on other things and letting the machine run its own start-up and shut-down of functions such as self-centre steering, activation of depth control, changing direction of cross conveyor and switching on the driven scrubber web.

The machine can be specified with or without a stone box, and can be fitted with hydraulic or air brakes.
