Abstract

A work vehicle, in particular an agricultural or construction tractor, has a cab the lower portion of which lies partially between the vehicle's rear wheels and covers at least part of the power train. To provide adequate access for maintenance, repair, exchange and cleaning of the components beneath the cab without great difficulty and with little expenditure of time, the cab can, after removal of a rear wheel, be tilted laterally about a tilt axis approximately parallel to the longitudinal axis of the vehicle. The tilt angle is approximately 60.degree. to 110.degree., and preferably about 90.degree.. A readily transportable tilting apparatus also is provided which includes a hand-cranked spindle assembly for mounting to the chassis beneath the cab. This tiling apparatus is rigidly fastened to the chassis perpendicular to the longitudinal axis of the vehicle, and includes a lifting arm fastenable to the cab and projecting outward over the tilt axis and a connector pivotally connecting the free end of the projecting lifting arm to the spindle follower. Preferably, an upper-link of the three-point hitch typically found on this type of vehicle is used as the connector.
