Abstract
A no-till seed planter includes a wheel mounted frame having at least one rock shaft carrying a rank of seed planting assemblies connected to the rock shaft by torque arms. A torsion joint connects each torque arm to the rock shaft and permits resilient rotation of the torque arm on the rock shaft. A stop block assembly on the rock shaft limits the amount of permissible rotation of the torsion joint on the rock shaft in order to avoid damage to the torsion joint and dislocation of the torsion joint. The torque arm is a composite structure of a main member connected to the torsion joint at one end and to a planter assembly at the other. In one embodiment leaf members are connected to the torsion joint and extend alongside the main member to an intermediate location on it. The leaf members buffer side-to-side deflection of the main member. The planter assembly includes a furrowing disk and a depth gauge tire spaced from the disk. A flexible boot extends from the tire toward the disk with an outer edge that can make surface contact with the side surface of the disk in order to prevent a dirt accumulation on it. The outer edge is prone to wear. The tire is mounted on a laterally adjustable axle to permit adjustment of the space between the tire and the side of the disk in order to compensate for wear on the edge of the boot.
