A skid steer loader having a main frame including a compartment in which an engine and transmission components are contained, ground support wheels extending from the main frame, and a cab mounted on the main frame. The cab includes load bearing side walls extending upwardly from the main frame to define an operators control area therebetween. A boom assembly comprising a pair of arms having material handling front portions and linkage structure that operatively attaches the arms to the cab side walls. The linkage structure includes an upper link coupled to each of the arms and pivotally secured to the cab at a location above the top surface of the wheels, and a lower link which is also pivotally secured to the cab at a location above the wheels. The boom assembly raises and lowers the pair of arms through a generally vertical path adjacent the corresponding load bearing side walls and above the wheels which maximizes the space available in the operator control area, whereas the front portions of the boom arms are thereby moved along generally vertical side-by-side paths.
