Caterpillar integrated the four towed-scraper models acquired with the E-Ject Systems purchase into its product line. The TS180 and TS220 are two-wheel units with heaped capacities at 19 cubic yards, and the TS185 and TS225 are four-wheels pans with walking-beam suspension and heaped capacity of 23.5 cubic yards. All of the Cat towed scrapers come standard with dry-disc brakes. The center-lift bowl eliminates the large draft arms (external supports) and saves weight.
