Agricultural implement

An agricultural implement comprising a first frame portion having means thereon for coupling to a tractor or the like, said first frame portion being substantially horizontal and disposed substantially transverse to a direction of movement when the implement is in operation, a second frame portion having first and second ends and said first end pivotally connected to said first frame portion along a first vertical pivot shaft, means adjacent said first pivot shaft for permitting said second frame portion to deflect with respect to said first frame portion only when a force above a pre-determined magnitude is exerted on said second frame portion in a direction opposed to the direction of movement in operation of the implement, a carrier having working tools mounted thereon and pivotally connected by a second vertical pivot shaft to said second end of said frame portion, said second pivot shaft being spaced from said first pivot shaft in a direction away from said first frame portion, and a spring device between said carrier and said second frame portion extending a force such that an end portion of said carrier on a side of said second pivot shaft remote from said first frame portion can deflect in the direction of movement in operation.
