A safety and control device working on a moderator brake for agricultural motor hoes for dampening vibrations, shocks or jerks transmitted to the driving handle (1) and for controlling the forward motion and the working depth (P) of the machine. The member (A) of the device penetrates the soil beyond the tangential plane determinated by the operating part of the motor hoe so allowing the member (B) to rest and slide on the same tangential plane, and determinating as a consequence a cut in the compact soil underlying the device, down to a constant and adjustable depth (h). Such condition determines the braking, adjusting and stabilizing action imposed by the device itself on the machine as an effect of the resisting force (7). |
