Abstract: A mulcher that includes a longitudinal member having one end adapted for connection to a mobile power source, a beam member extending transversely of the connecting member and connected thereto and also having a downwardly opening channel configuration, a generally curved bar located in the channel configuration, a mounting structure for connecting the curved bar to the beam member and a spring tooth structure having a pair of spaced axially aligned coil portions and an intervening connector portion pivotally mounted on the curved bar with a tooth portion extending downwardly from the endmost convolutions of the coil portions. The connector portion engaging the mounting structure when the mulcher is towed and the tooth portions engage the soil with the coil portions winding up on the curved bar. The connector portion moving away from the mounting structure until the tooth portions contact the channel when the mulcher is backed up with the tooth portions in the soil.

Abstract: A mechanism for folding the wings of a multi-section implement from a transversely extending working position to a latched, vertical transport position relative to the main section and return. The mechanism includes a hydraulic cylinder that extends between the main section and each wing and a support and latch assembly. This assembly includes a fixed support on the main section and a telescoping tube for each wing which has its outer end pivotally connected to the wing and its inner end pivotally attached to the support. A latch structure is attached to the inner end of each tube and includes a crank arm pivotally mounted on the latch structure and pivotally connected to the rod of a single cylinder. A lever extends from this connection to a slidable mount on a slotted hole in the fixed support. The latch structure has a spring loaded tongue that engages a ramp having an aperture therefor on the outer end of each tube to latch the inner and outer ends of each of the tubes together.
