Generous storage space includes: lockable compartment for personal items; a coat hook; molded compartments for lunchbox, cooler, thermos, cup or can.

The ventilation is improved for better air flow to the operator and windows. Six repositioned vents throughout the cab keep air flowing.

Third Valve Control
Third valve control for actuating the quick coupler pin to retain attachments, or for controlling the hydraulic flow when using powered attachments.

Ride Control Switch
The ride control switch allows the selection of three different modes.

Operator's Choice
Two-position return-to-work kickout switch allows the operator to choose between return-to-work positions for two different attchments.

Radio-ready means this cab includes a 12-volt converter, two speakers, antenna, wiring and brackets for entertainment radio installation.
