Abstract
A control mechanism (14) associated with a tractor operators seat (110) and an arm rest (112) is disclosed which includes a steering selector apparatus (116) having an upstanding member (134) and a tiller arm (118) extending outwardly therefrom. The tiller arm (118) is advantageously located immediately forwardly of the arm rest (112) and has a mounting portion (142) and hand grip portion (144) that can be easily grasped by an operator's downwardly facing hand palm. A support assembly (136) pivotally supports the upstanding member (134) for movement about a fixed upstanding axis (140) and a control device (46,50,52,54,184) steers the tractor in response to the swinging movement of the tiller arm (118). In response to rotation of the hand grip portion (144) about the axis (158) of the tiller arm (118) a second control device (38,42,174) effects a change in the gear condition of an associated transmission (36).
