Articulation

Twin 4.5" (114 mm) hydraulic cylinders articulate frame 22º right and left. Anti-drift lock valve ensures stable operation.

Circle

Hardened teeth, cut on the outside of the circle for maximum leverage and minimum wear.

The circle is supported at six points by three adjustable clamp plates and three adjustable guide shoes, providing optimum circle support and load distribution. DURAMIDE™ faced clamp and guide shoes prevent metal-to-metal contact and provide maximum service life.

DURAMIDE™ is a synthetic bearing material that maximizes service life and reduces circle system maintenance requirements.

Circle drive

The Volvo dual cylinder Circle Drive System uses direct acting hydraulic power for exceptional turning and holding capability under full load. Circle Drive System uses hardened drive pinions and is protected against impact damage by an overload cushion valve as standard equipment.

Cab & controls

All controls are located in a 90° arc forward and to the right of the operator. Located forward of the operator are the engine oil pressure, coolant temperature and fuel level gauges, transmission gear indicator and a multi-function Contronic monitoring display. Located in the fully adjustable steering pedestal are the following switches: differential lock/unlock, hazard lights, combination turn signal, horn and high beam headlight. Heater and wiper/washer controls, lighting and accessory switches are grouped in the operator’s right hand console. This console
