A four post ROPS is provided with left and right front vertical posts and left and right rear vertical posts. The rear vertical posts have a bottom portion that extends upwardly, forwardly and outwardly from the floor of the operator's station. Each left and right front vertical post has an arrowhead shaped cross section. The arrow shaped cross section has a main lobe, a secondary lobe and a connecting portion located between the two lobes. The arrowhead shaped cross section defines a windshield channel for receiving the side edge of the windshield, and a side door channel for receiving the side edge of the side door. The arrowhead shape has an elongated axis that is in line with the line of sight of the operator when driving the backhoe loader.
