Abstract
A soil treating system having a frame, a first implement to engage soil to effect treatment thereof and mounted to the frame in an operative position in which the implement can be moved vertically relative to the frame, and an hydraulic actuator acting between the frame and implement for exerting a variable downward force on the implement.
Claims15
A soil treating system comprising:
- a frame;
- a first implement to engage soil to effect treatment thereof;
- means for mounting the first implement to the frame in an operative position in which the first implement can be moved vertically relative to the frame;
- and
- first hydraulically actuated means acting between the frame and first implement for exerting a variable downward force on the implement,
- wherein there is a second implement to engage soil to effect treatment thereof, there is a second means for mounting the second implement to the frame in an operative position in which the second implement can be moved vertically relative to the frame and a second hydraulically actuated means acting between the frame and second implement for exerting a downward force on the second implement, an accumulator is provided for hydraulic fluid and means are provided for establishing direct fluid communication between the accumulator and each of the first and second force exerting means.
