Abstract
Disclosed are front entry cabs, and power machines with front entry cabs, having a door that is moveable between opened and closed positions. In the opened position, the door is positioned within an operator compartment of the cab above the operator seat and below a top of the cab. A linkage system defines the travel path of the door between closed and opened positions. The linkage system is configured to minimize interference with operator visibility.
