An air filter (17) is provided in the passage for filtering the air drawn in through the air intake (11) on its way to the heating and/or ventilating unit (13). A filter sealing surface (34) bounds part of the air passage for co-operating with the filter to ensure that the air passing through the passage passes through the filter. The filter (17) is inserted into and removed from the air passage via a filter access opening (18) which is closed by an access hatch (19) in the roof of the cab and filter securing means, in the form of wedges (20) on the underside of the hatch, ensure that, when the access hatch (19) closes the opening, the filter (17) is secured against the sealing surface (34). The access hatch 19 can be reached by an operator standing in the cab with his head and shoulders poking through an open escape hatch (35) which is provided in the cab roof adjacent the access hatch.
