Patent number: 4930297Abstract: Cotton harvester basket structure including an upper basket portion telescopingly received within a lower basket portion and first hydraulic actuators for moving the basket between harvesting and dump positions and second actuators for telescoping the basket portions between a retracted storage position and an extended field-working position. An unloading conveyor and compacting augers are connected to and movable with the upper basket portion, and the compacting augers also serve to meter cotton during the dump cycle. Telescoping cotton conveying ducts are movable with the upper basket portion between retracted transport and raised field-working positions. Hydraulic circuitry includes valves for selectively controlling the basket telescoping and dump functions and the conveyor and compacting auger operations.Type: GrantFiled: October 11, 1988Date of Patent: June 5, 1990Assignee: Deere & CompanyInventors: Francis E.

Patent number: 4926624Abstract: A lawn mower comprising a cutting unit disposed between front and rear wheels, a grass discharge duct extending rearwardly from the cutting unit, and grass collecting containers each defining a top opening for receiving grass clippings sent through the discharge duct. The containers are supported by an E-shaped frame connected to, and retained by pins in, open rear ends of right and left pipe frames extending rearwardly and then upwardly from a mower body. The E-shaped frame engages the open rear ends of the pipe frames to interconnect the rear ends with a selected spacing therebetween.Type: GrantFiled: April 3, 1989Date of Patent: May 22, 1990Assignee: Kubota, Ltd.Inventors: Masatake Murakawa, Niro Bando, Masatsugu Tone, Mikio Yuki, Junji Miyata, Tetsuaki Hayashi, Kazuaki Kurohara

Patent number: 4924664Abstract: A ducted cover grass collection system for a lawn mower includes a hopper with a front end having an inlet, a rear end having an outlet and an open upper end, a deflector hood located at the front end to partially cover the open upper end, and a lid covering the remainder of the open upper end, the lid having a duct open at a front end and having a rear end in communication with the outlet so that a flow of clippings and air is introduced through the inlet and projected generally horizontally toward the rear end of the hopper, so that the clippings settle to the bottom of the hopper, after which the air is directed back toward the deflector hood, through the duct and is discharged via the outlet. An air flow indicator located in the hopper lid pivots when the air flow in the duct decreases, signaling that the hopper is filled with clippings.Type: GrantFiled: October 18, 1988Date of Patent: May 15, 1990Inventors: John E. Hicks, Michael E. Allen

Patent number: 4907403Abstract: An improved grass mower and attachment which employs a sling for holding a disposable bag is disclosed. The sling is open to one side so that full bags can be unloaded without lifting. The sling is mounted to a frame which receives the margin of the bag and this frame is mounted so that it can both pivot downward (when unlatched) and slide rearward relative to a housing from which clippings are delivered to the bag during grass cutting. When the bag is desired to be unloaded, the frame is unlatched and the sling, which is otherwise held above the ground, pivots its open side down to the ground. The housing can slide from over the frame by advancing the mower. The filled bag can be then tied and rolled out of the sling onto the ground without lifting it. A new bag can be fitted to the frame, inside the sling, and the lightweight frame, sling and empty bag returned and relatched under the housing and the mower used to fill the new bag.Type: GrantFiled: February 6, 1989Date of Patent: March 13, 1990Inventor: Otis Jones

Patent number: 4903469Abstract: A lawn mower comprising a cutting unit disposed between front and rear wheels, a grass discharge duct extending rearwardly from the cutting unit, and a grass collecting container defining a top opening for receiving grass clippings sent through the discharge duct. The grass collecting container includes a mouthpiece extending along peripheries of the top opening to rest on a U-shaped support frame mounted at a rear end of the mower. The mouthpiece is connected to the support frame by a projection and bore engagement. The support frame includes a holder defining an upwardly opening recess, and the container has a cover defining a downwardly opening recess at a position opposed to the holder. The two recesses define an opening for receiving a rear end of the grass discharge duct. The grass discharge duct includes an annular engagement portion extending peripherally of the rear end thereof for engagement with inner edges of the two recesses.Type: GrantFiled: October 16, 1987Date of Patent: February 27, 1990Assignee: Kubota, Ltd.Inventors: Masatake Murakawa, Niro Bando, Masatsugu Tone, Mikio Yuki, Junji Miyata, Tetsuaki Hayashi, Kazuaki Kurohara

Patent number: 4888940Abstract: Hydraulically driven compacting augers are supported within a cotton basket and are connected for operation to a hydraulic source through a remotely actuatable reversing valve. The augers are rotated a first direction to compress the cotton toward the front of the basket as the air duct system blows the cotton rearwardly into the basket. After the cotton is compacted toward the front of the basket, the reversing valve is actuated to cause the augers to rotate in the opposite direction and compress the cotton toward the rear of the basket. The augers additionally serve to help meter the cotton from the basket during dumping and are reversible during dumping.Type: GrantFiled: January 27, 1989Date of Patent: December 26, 1989Assignee: Deere & CompanyInventor: Timothy A.
