The four-cylinder Cat® M300D Series Wheeled Excavator models—M313D and M315D—have earned a solid reputation for reliable performance, long-term durability, versatility, fuel efficiency and low operating costs. Recent engineering updates have further strengthened these qualities with refinement of the operator’s station and undercarriage, along with new technical features and fleet-management systems. The new models provide a more-flexible design, greater operator comfort, enhanced serviceability, and more effective asset management.

New for the M313D and M315D is a welded undercarriage that allows a blade to be used either front or rear, with or without outriggers at the non-blade end. Or, the machines can be fitted with outriggers front and rear. This versatility allows customers to tailor machine configuration to typical applications.
The M313D and M315D can be equipped with the Cat Product Link system, which is deeply integrated into machine systems to allow remote monitoring of such data as location, event codes, diagnostic codes, hours, fuel usage and idle time, as well as allowing mapping functions, such as geo-fencing. Using a powerful telemetric system, Cat Product Link transmits this information to the customer and the dealer via a secure, web-based application, VisionLink™.
The Cat Machine Security System (MSS) is another asset-management tool available for the new excavators (standard in North America and EU). The MSS, which uses special keys with an electronic chip, controls who can operate the machine (and when). The MSS, using a small antenna around the key switch to read the user’s identity, then checks if the operator is authorized. Master Access Level keys allow using the Caterpillar Electronic Technician system to configure the security system.
