Product Description

Bobcat® 444

Comfortable cab

The full-vision cab is acoustically insulated to keep the sound level down, providing a comfortable working environment. The suspension seat is fully adjustable for weight, height and backrest angle. A def ector on the front of the cab prevents water entering it, and keeps the operator dry even in the worse weather conditions.

Operator-friendly instrument panel

Conveniently located on the right-hand side of the operator, the instrument panel

displays clear information on all operating functions.

 

Anti-drop safety valve

Standard equipment includes a safety (antidrop) boom valve for lifting applications as well as a load moment device to keep the operator informed of the stability limit of the excavator. If necessary, the load moment device can be switched off. The standard equipment also includes an anti-drop valve for the blade.

 

Exceptional stability

The rugged oversized undercarriage ensures exceptional longitudinal and

lateral stability.
