Abstract

A machine for controlling and eventually eradicating cactus and other succulent plants in farm and ranch pastures and other lands and land uses. This apparatus for mechanically controlling and eradicating cactus and other succulent plants uses a cutter deck on the machine to break off cactus pads near ground level. The tool uses a crushing rail to crush and mangle cactus pads and large portions of other succulents increasing the probability that the plant parts will not reroot. The machine in its preferred embodiment is towed by a tractor or other vehicle. A preferred embodiment includes a ballast rail to increase the weight of the tool and enhance the crushing action and a chain tow bridle to attach the tool to the towing vehicle. Another preferred embodiment includes a loop forming bolt to hold the bridle.

Claims

1. An apparatus for mechanically controlling and eradicating target plants from farm and ranch pastures and other lands comprising:

a base for dragging over terrain for removal of target plants;

a rail having a cross sectional shape with a protruding forward surface disposed transversely to the forward movement of said base and on the underside of said base to crush and mangle said plants;

a plurality of skids at the leading bottom edge of said base to prevent the base from digging into the ground; and

a space between the leading edge of the base and the crushing rail.

2. An apparatus for mechanically controlling and eradicating target plants from farm and ranch pastures and other lands as claimed in claim 1 further comprising a ballast rail to increase the weight of the tool and enhance the crushing action.

3. An apparatus for mechanically controlling and eradicating target plants from farm and ranch pastures and other lands as claimed in claim 2 further comprising a chain tow bridle to attach the tool to the towing vehicle.

4. An apparatus for mechanically controlling and eradicating target plants from farm and ranch pastures and other lands as claimed in claim 3 further comprising a loop forming bolt to hold the bridle.

5. An apparatus for mechanically controlling and eradicating target plants from farm and ranch pastures and other lands as claimed in claim 2 further comprising a cable assembly to attach the tool to the towing vehicle.

8. An apparatus for mechanically controlling and eradicating target plants from farm and ranch pastures and other lands as claimed in claim 3 further comprising a chain tow bridle to attach the tool to the towing vehicle.

9. An apparatus for mechanically controlling and eradicating target plants from farm and ranch pastures and other lands as claimed in claim 8 further comprising a loop forming bolt to hold the bridle.

6. An apparatus for mechanically controlling and eradicating target plants from farm and ranch pastures and other lands comprising:

a cutter deck on the drag tool to break off target plants near ground level;

a crushing rail having a generally rounded forwardly protruding surface to crush and mangle target plants increasing the probability that said plants will not reroot;

a stabilizer to prevent the tool from turning over when used on uneven terrain;

a plurality of skids at the cutter deck leading edge to prevent tool from digging into the ground;

a crushing gap between the cutter deck and the crushing rail to increase surface wounds on said plants; and

an adjustment assembly for varying the deck length to accommodate treatment on varying types of terrain.

7. An apparatus for mechanically controlling and eradicating target plants from farm and ranch pastures and other lands as claimed in claim 6 further comprising a ballast rail to increase the weight of the tool and enhance the crushing action.

10. An apparatus for mechanically controlling and eradicating target plants from farm and ranch pastures and other lands as claimed in claim 7 further comprising a cable assembly to attach the tool to the towing vehicle.
