Abstract: A novel collapsible aeration system is retrofitted into a grain bin with a discharge opening in the bottom. This grain bin may have a sloped or conical hopper or a flat bottom. The aeration system is formed from a set of connected (e.g. hinged) duct sections that define a round or multi-sided duct having a minimum of three sides or faces. The sides may be flat, curved or corrugated. The collapsible aeration system is folded (collapsed), inserted into the bin via a hole, and then unfolded inside the bin. An air duct is connected to the aeration system to enable the aeration system to dry the grain in the grain bin. This technology enables existing grain bins to be retrofitted with a dryer in an easy and efficient manner.

Abstract: A cutting machine comprising a chassis connected to a motor vehicle, a cutting device comprising cutting members, a connecting device connecting the cutting device to the chassis in such a way as to allow the cutting device to be brought into a work position and into a transport position and comprising at least two connecting rods each one connected to the cutting device and to the chassis by means of a respective connection, one of the connections being a connection of the ball-joint type. The cutting machine is characterized in that at least one of the connections connecting a connecting rod to the cutting device or to the chassis comprises an elastic element.

Abstract: A grass catcher for receiving air and grass clippings from a mower cutter deck includes an inlet for admitting air and clippings into the grass catcher, an outlet port for exhausting air out of the grass catcher, and at least two cylindrical, perforate air filters interposed between the inlet and the outlet port. The filters separate grass clippings from the air and permit air to pass through the filters and on to the outlet port. The grass catcher also includes a wave form energy transmitter and a wave form energy receiver positioned in the grass catcher. The transmission of wave form energy between the transmitter and the receiver is interrupted when the level of accumulated grass clippings in the catcher exceeds a predetermined level. The interruption of the transmission triggers an alarm to alert an operator of the mower of the high clipping level within the catcher.

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: A mowed grass container for a mowing machine having a mower attached to a machine body through a hanging link mechanism for recovering mowed grass mowed by said mower to the mowed grass container attached to the machine body through conveying means comprising a shielding plate coupled to the machine body, an upper cover aligned in parallel above and below the side face of said shielding plate, and a lower mowed grass containing unit, said lower mowed grass containing unit being opened at the upper face thereof and at the face adjacent the shielding plate side. The grass container is detachably attached to said shielding plate through a pivot provided at position separated from said shielding plate so as to rotate about the pivot as a rotating center with the open face of the grass container being directed downwardly.

Abstract: Grass cutting machine with tip-up box comprising a frame (1) mounted on wheels (2) and supporting a horizontal shaft (3) provided with rotating blades (4) and a box (8), movable from a lower position for collecting the cut grass to an upper position for discharging the cut grass into a dumper. The box (8) is upperly provided with a hinged cover (12) and is connected to the frame (1) by two telescopic guides (13), to the upper end of which it is joined so that it can be tipped up at the end of the lifting stroke and discharge the cut grass into the dumper, through the aperture closed by said cover and directed downwards, following to said tipping.

Abstract: The grass catcher includes a disposable perforated catcher bag for connection to the discharge chute of a lawn mower. A catcher housing supports and surrounds the perforated bag in a manner which protects the mower operator and bystanders from being hit by projectiles which may pierce the bag. The housing includes a solid base pan which hooks onto the mower rear axle and a vertical shield which is hinged to the base and hooks onto a portion of the mower handle. A hood is hinged to the mower housing in a manner allowing it to cover the base pan and bag or be swung forward on the mower to expose the catcher bag. The shield can be unhooked and laid flat to provide greater exposure to the catcher bag. The mounting for the catcher allows for some vertical movement brought about by contact between the catcher base pan and the ground caused by the mower traversing rough or uneven terrain.
