Claim 3

An implement according to claim 1 wherein said power means comprises a hydraulic cylinder connected to said frame and to said cross member and said opposite end of said cross member is slidably received between a pair of spaced frame members extending generally in the direction of the length of said frame.

Claim 4

An implement for use in rice farming, and particularly the areas of a rice paddy immediately adjacent a levee, comprising: means defining a vehicle frame having a forward end adapted to be secured to a tractor or the like, a pair of opposed sides and a rear end; means defining a disc gang; means securing said disc gang to said frame adjacent the forward end thereof, such that an end of said disc gang adjacent one of said frame sides will be lower than the opposite end of said disc gang when said implement is in use, said disc gang further being angularly mounted on said frame with respect to said frame forward and rear ends so as to have said end thereof forwardly of the other end of said disc gang whereby earth will be moved toward said one frame side; seed feeding means extending across said frame and located to the rear of said disc gang for feeding seed to the ground over which said implement may be operated behind said disc gang; and harrow means affixed to the rear end of said frame means behind said seed feeding means for smoothing the ground after it has been seeded by said seed feeding means; whereby said implement permits full use of a rice paddy by said disc means filling the furrow adjacent the levee, said seed feeding means seeds the filled furrow adjacent the levee and said harrow means smoothes the filled and seeded furrow, said frame further including an elongated frame member extending rearwardly from the end of said frame and said harrow means comprising a plurality of cross members elongated generally in a direction transverse to the length of said frame, each of said cross members mounting a plurality of downwardly extending teeth, and a plurality of links connected to each other and to said cross members and extending in a direction along the length of said implement, and means flexibly interconnecting said harrow means and said rearwardly extending member whereby when said implement is connected to the three-point hitch of a tractor or the like, elevation of the implement operation of the tractor''s three-point hitch will result in said harrow means being substantially elevated above the terrain over which the implement is moving.

Claim 5

An implement for use in rice farming, and particularly the areas of a rice paddy immediately adjacent a levee, comprising: means defining a vehicle frame having a forward end adapted to be secured to a tractor or the like, a pair of opposed sides and a rear end; means defining a disc gang; means securing said disc gang to said frame adjacent the forward end thereof, such that an end of said disc gang adjacent one of said frame sides will be lower than the opposite end of said disc gang when said implement is in use, said disc gang further being angularly mounted on said frame with respect to said frame forward and rear ends so as to have said end thereof forwardly of the other end of said disc gang whereby earth will be moved toward said one frame side; seed feeding means extending across said frame and located to the rear of said disc gang for feeding seed to the ground over which said implement may be operated behind said disc gang; and harrow means affixed to the rear end of said frame means behind said seed feeding means for smoothing the ground after it has been seeded by said seed feeding means; whereby said implement permits full use of a rice paddy by said disc means filling the furrow adjacent the levee, said seed feeding means seeds the filled furrow adjacent the levee and said harrow means smoothes the filled and seeded furrow, said frame further including an elongated frame member extending rearwardly from the end of said frame and said harrow means comprising a plurality of cross members elongated generally in a direction transverse to the length of said frame, each of said cross members mounting a plurality of downwardly extending teeth, and a plurality of links connected to each other and to said cross members and extending in a direction along the length of said implement, and means flexibly interconnecting said harrow means and said rearwardly extending member whereby when said implement is connected to the three-point hitch of a tractor or the like, elevation of the implement operation of the tractor''s three-point hitch will result in said harrow means being substantially elevated above the terrain over which the implement is moving.

Claim 6

An implement for use in rice farming, and particularly the areas of a rice paddy immediately adjcent a levee, comprising: means defining a vehicle frame having a forward end adapted to be secured to a tractor or the like, a pair of opposed sides and a rear end; means defining a disc gang; means securing saiD disc gang to said frame adjacent the forward end thereof, such that an end of said disc gang adjacent one of said frame sides will be lower than the opposite end of said disc gang when said implement is in use, said disc gang further being angularly mounted on said frame with respect to said frame forward and rear ends so as to have said end thereof forwardly of the other end of said disc gang whereby earth will be moved toward said one frame side; seed feeding means extending across said frame and located to the rear of said disc gang for feeding seed to the ground over which said implement may be operated behind said disc gang; and harrow means affixed to the rear end of said frame means behind said seed feeding means for smoothing the ground after it has been seeded by said seed feeding means; whereby said implement permits full use of a rice paddy by said disc means filling the furrow adjacent the levee, said seed feeding means seeds the filled furrow adjacent the levee and said harrow means smoothes the filled and seeded furrow, said frame mounting at least one ground engaging wheel, all said wheels being remote from said frame one side; and said disc gang one end extends at least to said frame one side whereby said implement may be operated in virtual abutment with a levee to completely fill, seed, and smooth the adjacent furrow.

Claim 7

An implement for use in rice farming, and particularly the areas of a rice paddy immediately adjcent a levee, comprising: means defining a vehicle frame having a forward end adapted to be secured to a tractor or the like, a pair of opposed sides and a rear end; means defining a disc gang; means securing saiD disc gang to said frame adjacent the forward end thereof, such that an end of said disc gang adjacent one of said frame sides will be lower than the opposite end of said disc gang when said implement is in use, said disc gang further being angularly mounted on said frame with respect to said frame forward and rear ends so as to have said end thereof forwardly of the other end of said disc gang whereby earth will be moved toward said one frame side; seed feeding means extending across said frame and located to the rear of said disc gang for feeding seed to the ground over which said implement may be operated behind said disc gang; and harrow means affixed to the rear end of said frame means behind said seed feeding means for smoothing the ground after it has been seeded by said seed feeding means; whereby said implement permits full use of a rice paddy by said disc means filling the furrow adjacent the levee, said seed feeding means seeds the filled furrow adjacent the levee and said harrow means smoothes the filled and seeded furrow, said frame mounting at least one ground engaging wheel, all said wheels being remote from said frame one side; and said disc gang one end extends at least to said frame one side whereby said implement may be operated in virtual abutment with a levee to completely fill, seed, and smooth the adjacent furrow.
