摘要： A spring tooth harrow comprising an elongated tool bar having a plurality of harrow sections secured thereto by adjustable mounting brackets to enable the harrow section to be raised or lowered with respect to the draw bar. Each harrow section includes a pair of longitudinally extending arms which are pivotally secured to the mounting brackets and which are urged downwardly with respect thereto by pairs of springs. Fork pipes are rotatably mounted on the arms and extend therebetween and have spring teeth secured thereto. The pipes may be rotatably moved in unison to change the angle of attack of the spring teeth or the forwardmost pipe may be independently rotated with respect to the remaining pipes so that the angle of attack of the forwardmost spring teeth may be varied with respect to the trailing spring teeth.

摘要： A spring tooth harrow packer comprising a transversely extending draw bar which is wheel supported and which has a hitch extending forwardly therefrom for attachment to a tractor. A plurality of harrow sections are secured to the draw bar and are positioned rearwardly thereof which each of the harrow sections including a plurality of ground engaging spring teeth. A packer is mounted on the rearward end of each of the harrow sections and is pivotally secured thereto for selectively controlling the penetration depth of the teeth of the associated harrow section.
