Trash seeder

Claim 2

A trash seeder comprising an implement frame carrying at least one seeding tyne, and a press wheel rearwardly of said seeding tyne, said press wheel being carried by a rigid main frame pivoted to said implement frame, said seeding tyne being pivoted rearwardly of said main frame pivot to a second frame pivoted to said implement frame, said second frame adapted to apply downward force to said rigid main frame, and resilient means applying downward pressure to said tyne, said seeding tyne being pivotable upwardly relative to said rigid main frame to clear an obstruction while downward pressure is maintained on said press wheel.

Claim 3

A trash seeder as defined in claim 1 characterized by said second frame being pivoted to said implement frame at the pivot of said main frame to said implement frame, and said tyne extends from a tyne frame pivoted to said second frame rearwardly of the pivot of said second frame to said implement frame, said resilient means comprising a hydraulic ram connected to said tyne frame remote from its pivot to said second frame.

Claim 4

A trash seeder as defined in claim 2 characterized in that said second frame engages the main frame whereby downward pressure applied to the tyne by the hydraulic ram is also applied to said main frame and said press wheel.

Claim 5

A trash seeder as defined in claim 3 characterized in that a stop is provided on said second frame to be engaged by upward movement of said tyne frame on the tyne encountering an obstruction, further movement of the tyne frame causing the second frame to move upwardly to allow the main frame to move upwardly to allow the press wheel to pass over the obstruction.

Claim 6

A trash seeder comprising an implement frame carrying at least one seeding tyne and a following press wheel, said press wheel being mounted on a trailing main frame pivoted to said implement frame by a pivot pin, a secondary trailing frame pivoted to said pivot pin, said secondary frame having means to engage said main frame, a trailing tyne frame pivoted at its forward end to said secondary frame by a second pivot pin spaced rearwardly of said first pivot pin, said tyne being carried by said tyne frame, a hydraulic ram connected to said tyne frame to apply downward pressure along said tyne frame, a stop on said secondary frame to engage by said tyne frame when said tyne frame pivots upwardly on the tyne striking an obstruction, the arrangement being such that the pressure of the hydraulic ram supplied to the tyne frame and also to the secondary frame due to the pivoting of the tyne frame to the secondary frame at a location spaced from the first pivot pin, the secondary frame applying pressure to the press wheel, the tyne frame being able to pivot upwardly without release of pressure on the press wheel until the tyne frame contacts said stop on the secondary frame when the secondary frame is also lifted allowing the press wheel to rise.

Claim 7

A trash seeder comprising an implement frame carrying at least one seeding tyne and a following press wheel, said press wheel being mounted on a trailing main frame pivoted to said implement frame by a pivot pin, a secondary trailing frame pivoted to said pivot pin, said secondary frame having means to engage said main frame, a trailing tyne frame pivoted at its forward end to said secondary frame by a second pivot pin spaced rearwardly of said first pivot pin, said tyne being carried by said tyne frame, a hydraulic ram connected to said tyne frame to apply downward pressure along said tyne frame, a stop on said secondary frame to engage by said tyne frame when said tyne frame pivots upwardly on the tyne striking an obstruction, the arrangement being such that the pressure of the hydraulic ram supplied to the tyne frame and also to the secondary frame due to the pivoting of the tyne frame to the secondary frame at a location spaced from the first pivot pin, the secondary frame applying pressure to the press wheel, the tyne frame being able to pivot upwardly without release of pressure on the press wheel until the tyne frame contacts said stop on the secondary frame when the secondary frame is also lifted allowing the press wheel to rise.

Claim 8

A trash seeder as defined in claim 5 characterized in that said means on said secondary frame to engage said main frame are adjustable to vary the vertical position of the press wheel.

Claim 9

A trash seeder comprising an implement frame carrying at least one stump jump seeding tyne and a press wheel rearwardly of said seeding tyne, characterized in that said press wheel is carried by a rigid main frame pivoted to said implement frame by pivot means, a second frame pivoted to said implement frame, said seeding tyne being pivoted to said second frame rearwardly of said pivot means, resilient means applying downward pressure on said tyne, said second frame adapted to apply downward pressure from said resilient means to said rigid main frame to apply downward pressure on said press wheel, said seeding tyne pivoting upwardly relative to said rigid main frame to clear an obstruction while downward pressure is maintained on said press wheel.

Claim 10

A trash seeder comprising an implement frame carrying at least one stump jump seeding tyne and a press wheel rearwardly of said seeding tyne, characterized in that said press wheel is carried by a rigid main frame pivoted to said implement frame by pivot means, a second frame pivoted to said implement frame, said seeding tyne being pivoted to said second frame rearwardly of said pivot means, resilient means applying downward pressure on said tyne, said second frame adapted to apply downward pressure from said resilient means to said rigid main frame to apply downward pressure on said press wheel, said seeding tyne pivoting upwardly relative to said rigid main frame to clear an obstruction while downward pressure is maintained on said press wheel.

Claim 11

A trash seeder as defined in claim 7 characterized by said second frame being pivoted to said implement frame at the pivot of said main frame to said implement frame, and said tyne extends from a tyne frame pivoted to said second frame rearwardly of the pivot of said second frame to said implement frame, said resilient means comprising a hydraulic ram connected to said tyne frame remote from its pivot to said second frame.

Claim 12

A trash seeder as defined in claim 8 characterized in the said second frame engages the main frame whereby downward pressure applied to the tyne by the hydraulic ram is also applied to said main frame and said press wheel.
