Implement for preparing seedbeds
First Claim
1. Implement for working soil comprising a main frame, a hitch mounted on said main frame for attaching the main frame to a vehicle for towing the main frame along a path, said main frame extending substantially transverse to said path, scarifying teeth extending from said main frame for engaging the scarifying said soil, multiple tines extending from the main frame, said tines being spaced from one another along said main frame, said main frame being adjustable relative to the vehicle to move the scarifying teeth and tines into engagement with soil and an angle to work and grade soil, said main frame also being adjustable relative to the vehicle to move the scarifying teeth and tines out of engagement with said soil, a subframe mounted on said main frame by a pivot connection for pivoting along a substantially horizontal axis, a blade mounted on said subframe secured against movement relative to the subframe, said scarifying teeth located between said blade and said tines, said blade extending substantially parallel to said main frame whereby said blade is permitted to move relative to said tines, said subframe being movable about said axis from an upper position to a lowered position, and a manually releasable latching means for releasably latching said subframe in said upper position.

Abstract
An implement for preparing seedbeds and lawns includes a main frame member upon which are mounted scarifying teeth to penetrate the soil and tines which work the soil and prepare the final grade after the soil has been scarified. A subframe is pivotally mounted on the main frame and carries a grading blade ahead of the scarifying teeth when the implement is move in the forward direction. The blade is allowed to float relative to the main frame on the subframe to thereby knock down vegetation, remove rocks and lightly grade the soil. The subframe can be moved relative the main frame to a position lifting the scarifying teeth and the tines off of the ground and allowing the blade to provide a deeper grading of the soil or the subframe may be moved to a position lifting the blade off of the soil so that the sold is contacted only by the scarifying teeth and the tines. The implement can also be used to transfer soil to fill in low places, as the main frame member upon which the tines and scarifying teeth are mounted have a pair of intersecting lips which with the tines define a scoop that is capable of picking up limited amounts of soil and transferring the soil to low places when the implement is moved in the backward direction.

- 1. Implement for working soil comprising a main frame, a hitch mounted on said main frame for attaching the main frame to a vehicle for towing the main frame along a path, said main frame extending substantially transverse to said path, scarifying teeth extending from said main frame for engaging the scarifying said soil, multiple tines extending from the main frame, said tines being spaced from one another along said main frame, said main frame being adjustable relative to the vehicle to move the scarifying teeth and tines into engagement with soil and an angle to work and grade soil, said main frame also being adjustable relative to the vehicle to move the scarifying teeth and tines out of engagement with said soil, a subframe mounted on said main frame by a pivot connection for pivoting along a substantially horizontal axis, a blade mounted on said subframe secured against movement relative to the subframe, said scarifying teeth located between said blade and said tines, said blade extending substantially parallel to said main frame whereby said blade is permitted to move relative to said tines, said subframe being movable about said axis from an upper position to a lowered position, and a manually releasable latching means for releasably latching said subframe in said upper position.
- 3. Implement for working soil comprising a main frame including a pair of substantially parallel main frame members, a hitch mounted on one of said main frame members for attaching the frame to a vehicle for towing the frame along a path, said main frame members extending substantially transverse to said path, multiple tines extending from the outer main frame member, said tines being spaced from one another along said other main frame member, said main frame being adjustable relative to the vehicle to move the tines into engagement with soil at an angle to work and grade soil, said main frame also being adjustable relative to the vehicle to move the tines out of engagement with said soil, multiple rigid scarifying teeth rigidly mounted on said other main frame member, and a blade carried by said main frame between said main frame members, said blade being movable into a position engaging soil.
- 10. Implement for working soil comprising a main frame, a hitch mounted on said main frame for attaching the main frame to a vehicle for towing the main frame along a path, said main frame extending substantially transverse to said path, multiple tines extending from the main frame, said tines being spaced from one anther along said main frame, said main frame being adjustable relative to the vehicle to move the tines into engagement with soil at an angle to work and grade soil, said main frame also being adjustable relative to the vehicle to move the tines out of engagement with said soil, a subframe mounted on said main frame by a pivot connection for pivoting along an axis, and a blade mounted on said subframe and extending substantially parallel to said main frame whereby said blade is permitted to move relative to said tines, said main frame including guides engaging said subframe for restraining said subframe against substantial movement transverse to said main frame, said guides including restraining members defining a channel therebetween, said subframe including a pair of subframe members spaced transversely relative to said path, each of said subframe members being attached to said main frame at said pivot connection and including an extension slidably received in a channel defined by a corresponding one of said guides.
