Abstract: A vent system includes a vent stack for venting a tank fluid from a fuel tank that is external to the vent stack, during fuelling of the fuel tank. The vent stack includes a conduit including a conduit inlet and a conduit outlet, the conduit outlet opening to atmosphere external to the conduit. The vent stack also includes an opening into the conduit between the conduit inlet and the conduit outlet. The opening is fluidically connected, or connectable, to the fuel tank so the tank fluid from the fuel tank flows through the opening to the conduit outlet, in use. The vent stack also includes a fluid mover operable to cause a mixer fluid receivable in the conduit inlet to flow through the conduit towards the conduit outlet, thereby to mix the mixer fluid with the tank fluid in the conduit, upstream of the conduit outlet.

Abstract: Device for collecting or directly depositing cut grass for a lawnmower, mounted on the rear surface of a mower (2) and applied to the ejection channel (3) of this latter. The device has a removable bottom (4) detachably connected thereto, wherein after removal of the removable bottom (4) the device permits directly depositing the cut grass if collection is not desired. The removable bottom (4) is in the form of a rigid plate provided at one end with hooks (5) adapted to coact with a lower cross member (6) of the collecting apparatus and, at its other end, with a lock (7) for locking in closed position coacting with another lower transverse member (8) parallel to the first.

Abstract: Lawn mower characterized in that the rear drive wheels (4) are mounted on a rear interconnecting member (6) in the form of a portico permitting mounting of a receptacle (7) for receiving cut grass directly on the outlet opening of the ejection channel of the cutter housing (5) between the rear wheels (4).

Abstract: The present invention concerns a cutting head with synchronized counter-rotating blades and is characterized in that the ejection channel (4) progressively widens from the point of intersection (7) of the blades, by variation of the curvature of the interior surface (6') of the skirt enveloping the space (5) above each blade, up to the ejection opening.
