The Caterpillar M Series compact wheel loaders — 906M, 907M and 908M — use a 75-gross hp engine with an electronically controlled hydrostatic drive system that meets US EPA Tier 4 final emission standards.

They feature Caterpillar's exclusive Optimized Z-bar loader linkage, which combines aggressive digging power with parallel lift.  Electro-Hydraulic controls allow for engineering enhancements for the drive system, implement controls, auxiliary hydraulic system, and loader linkage. A range of work tools and couplers are available, ensuring optimum versatility and productivity. The compact wheel loaders can be used in landscaping, agricultural, industrial, snow removal, and general construction applications. 

The M Series features the Cat C3.3B engine, transversely mounted with easy service access for routine maintenance items. Single-plane coolers use a hydraulically driven fan or an optional Cat Demand Fan that operates at maximum speed only when required. An ECO mode regulates the engine’s high idle while maintaining full rimpull and breakout force capability — saving fuel and lowering sound levels for the most common tasks where maximum productivity is not required, according to the company. Exhaust after-treatment utilizes a diesel particulate filter to achieve emissions standards.

The Cat Hystat system can achieve up to a 22 mph top speed for these models with the optional stop-to-shift transmission that allows the operator to choose between max rimpull and max travel speed via a convenient switch on the RH console and automatically regulates speed during downhill travel.
