In 2009 Caterpillar integrated the four towed-scraper models acquired with the E-Ject Systems purchase into its product line. The TS180 and TS220 where two-wheel units with heaped capacities at 19 cubic yards, and the TS185 and TS225 where four-wheels pans with walking-beam suspension and heaped capacity of 23.5 cubic yards. All of the Cat towed scrapers came standard with dry-disc brakes. The center-lift bowl eliminates the large draft arms (external supports) and saves weight. Rear cylinders on the four-wheel TS185 and TS225 models allow the operator to adjust the cutting-edge angle to best accommodate different soils.

The Caterpillar TS Series Towed scraper can be pulled (in pairs) behind a Caterpillar D6 or D8 series Track Type Tractor or a Caterpillar Challenger (wheeled) Tractor.
