The 922F has six selectable work modes that equip even the newest operator with the skills of an expert. Allowing operators to to perfectly match machine performance with whatever job may come.

Features may include:

Power To Get The Job Done

The 922F Excavator is powered by the latest Cummins QSB6.7 engine in compliance with the strict Tier 4 Final emissions standards. The compact engine delivers unmatched and dependable power in its class yet produces virtually zero emissions. The hydraulic system is highly effective in delivering power and precise control to where the operator really needs it, making even the toughest job simple.

Onboard Monitoring

With onboard monitoring, the operator can check the machine's vital signs without leaving his seat. Using the LCD display, the operator can easily check oil temperatures and pressure levels, receive service interval alerts and access other information that contributes to simple maintenance and servicing of the machine.

Built Tough

The upper structure of the 922F is built around a reinforced and well-engineered H-beam, allowing the boom to be mounted exactly in the center of the machine. This central positioning helps the boom cope with more stress on the attachment group. It also means better distribution of weight and tension along the entire machine.
