Description: WHAT I CLAIM AS MY INVENTION IS:

1. An agricultural implement comprising a travelling framework, a plurality of pistons mounted on the frame work, standards in the form of piston rods extending from the pistons, carrying cutting members adapted to contact with the ground, and pneumatic means in connection with the pistons controlled from the driver's seat for raising and lowering said cutting members into and from contact with the ground.

2. An agricultural implement comprising a travelling framework, a plurality of cutting members carried by the framework, pneumatic means for forcing said cutting members into the ground to a uniform depth and for withdrawing said cutting members from contact with the ground.

3. An agricultural implement comprising a movable frame, a plurality of pistons mounted on said frame, a plurality of standards in the form of pistons extending from said cylinder, cutting members mounted on said standards and adapted to contact with the ground, an air tank on the framework, conduits connected with the tank and with the pistons, control member adjacent the driver's seat for con-: trolling the air supplied to the pistons, and means on the framework for constantly supplying air to the tank during the movement of the framework.

4. An agricultural implement comprising a movable framework, a plurality of pistons mounted on the framework in vertical relation, standards in the form of piston rods extending from the cylinders, soil cutting members mounted on the standards adapted to contact with the ground, an air tank on the framework, conduits connecting the air tank for supplying air to the top or base of the cylinders for forcing said cutting members to a uniform depth into the ground or raising said members from contact with the ground and means for constantly supplying the tank with compressed air on forward movement of the framework.

5. An agricultural implement comprising a movable framework, a plurality of pistons rigidly mounted on the framework, a plurality of standard members in the form of piston rods extending from the cylinders and carrying a plurality of soil cutting members, means for supplying compressed air to the top or base of the cylinders for forcing the cutting members into the ground or raising them from contact with the ground, means for maintaining a constant compressed air supply and means for automatically expelling the air from the top or base of the cylinders according to the movement of the pistons.

6. In an agricultural implement including, a movable framework having cylinders mounted thereon and a plurality of pistons operatively associated with the cylinders carrying cutting members, means for supplying compressed air to the cylinders for raising and lowering the cutting members to and from contact with the ground, and a controlling member in the form of a four-way valve for controlling the supply of air to the cylinders and discharging surplus air therefrom.

7. A device of the character described, comprising a travelling framework, a plurality of cutting members carried by the framework, pneumatic means for forcing said cutting members into the ground to a uniform depth and for withdrawing said cutting members from contact with the ground and a control member adjacent the driver's seat for controlling both the downward and upward movement to and from the ground of said cutting members.

8. An agricultural implement comprising a movable framework, a plurality of pistons rigidly mounted on the framework, a plurality of standard members in the form of piston rods carrying piston members extending from the cylinders and carrying a plurality of soil cutting members, means for supplying compressed air to the top or base of the cylinders acting on the piston members for forcing the cutting members into the ground or raising them from contact with the ground, means for maintaining a constant compressed air supply and a four-way valve for controlling the supply of compressed air to the cylinders end for releasing contained air in the cylinders according to the movement of the pistons.
