Overview

HIGH PERFORMANCE AND VERSATILITY IN A COMPACT MACHINE

The Cat® M315 Wheeled Excavator provides top performance to get the job done faster. Save time and money with low maintenance costs, longer service intervals, and 100 percent daily ground level maintenance. The compact radius design makes it easy to work in space restricted environments. The M315 gives you the power to work longer while putting money in your pocket.

Benefits

MAXIMIZE PERFORMANCE

Work faster with more swing torque. A smaller front and reduced tail swing radius lets you work in space-restricted areas.

UP TO 5% LOWER MAINTENANCE COSTS

Longer, synchronized service intervals, 100% daily ground-level maintenance and centralized grease points with an autolube option lower your overall costs.

ENHANCED COMFORT

Operate with ease. Easy to reach controls, a comfortable seat, and improved visibility let you work comfortably all shift long.
