Abstract: A structural orientation and protective apparatus is disclosed that is particularly useful in a tillage assembly for sod seeding purposes. The apparatus includes a pair of skids each of which is adjacent to a cutter wheel mounted on the tillage assembly for cutting a furrow in ground to be seeded, each skid including a ground engaging portion to determine the maximum depth of furrow cut by the cutter wheel. Each skid is mounted for pivotal motion about a horizontal axis at the forward end, with the forward end being inclined upwardly from the ground engaging portion. A vertical mounting plate on each skid has a bracket mounted therebetween at the rear portion to receive a vertical adjustment rod, one portion of which is connected to the frame of the apparatus for controlling the selected depth of furrow to be cut. A seed tube boot is fastened to the rear portion of the skid so that regardless of the selected depth of furrow cut, the tube remains in the same position relative to the ground. The particular positioning of the seed boot on the skid, as well as the particular structure of the skid itself, protects the seed boot against foreign objects that could damage or otherwise impair proper functioning of the seed boot.

Abstract: A dual packer unit is disclosed that is particularly useful for sod seeding purposes. The apparatus includes an H-shaped mounting bracket consisting of an arcuate leg connected at opposite ends to a pivot arm and a wheel mounting arm. The pivot arm is integrally formed with one end of the arcuate leg at the central portion of the pivot arm, and the wheel mounting arm is integrally formed with the other end of the arcuate leg at the central portion of the wheel mounting arm so that the ends of the pivot arm may be pivotally mounted between a pair of seed tubes, and packer wheels may be mounted for free rotation at the ends of the wheel mounting arms. When so mounted, each packer wheel is received in a furrow immediately following and in line with the seed tube. The packer wheels are gravity biased downwardly toward a cut furrow, and the unit therefore provides sufficient flexibility to follow the contour of the ground and to follow the cut furrow regardless of the depth selected.

Abstract: A depth control skid and seed boot assembly is disclosed that is particularly useful in a sod seeding implement for adjusting the maximum depth of cut of a cutting wheel and for adjusting the depth of the seed boot independently of each other. An arm rotatably mounting a pair of cutting wheels slidably receives the forward section of the skid. The rear of the skid is bolted to a bracket assembly vertically positionable with respect to the arm for adjusting the depth of cut. The bracket assembly pivotally carries the seed boot which is yieldingly and adjustably held in position with respect to the ground by a bolt and spring assembly. The seed boot can pivot upwardly against the bias of the spring out of the way of obstacles.

Abstract: The monitor is used with seeder equipment having one or more seeder hopper sections wherein each hopper section has a number of metering assemblies for feeding the seed from each hopper section to the soil. The monitoring apparatus includes at least one sensor consisting of a piezoelectric transducer which provides an output signal in response to being struck by a seed, a vibration isolating mounting structure to position the sensor in the seed flow path between the metering assembly and the soil, and a circuit for receiving the sensor electronic response and providing an indication of seed flow condition. The mounting structure includes an elongated member such as a metal tubing, to one end of which is fixed a cushion made of a material such as a closed cell foam and to the other end of which is fixed a securing member to secure the structure to the seeder. The sensor is positioned on the cushion and a pair of leads connected across the sensor, pass through the tube and are connected to twin conductors at the other end. The circuit for each sensor includes a control circuit which processes the sensor signal and which provides an output control signal representing a flow condition such as the no flow condition. The circuit further includes visual and audio alarm circuits which indicate the flow condition for each sensor.
